Huffman compress on NYX 512^3 (Hopper) improved ~1.9x (155 -> 298 GB/s), byte-identical output, all 48 ctests pass. Quantization / dictionary shift: - Fold the +dict_size/2 shift into quantize/dequantize (prep_huffman), removing the standalone full-array DictionaryShift passes on both compress and decompress. Outlier separation: - Block-aggregated atomics: per-block shared-memory slot reservation plus one device-scope atomic per block (was up to blockDim contended global atomics). Restore is a sparse scatter over the outlier count only. Encoding (fused): - Drop the EncodeFixedLen pass and the primary_count-sized huff_array; the deflate kernels look up codebook[data[i]] on the fly. GetCodebook takes primary_count explicitly. Deflate / packing (parallel, zero-copy): - Replace the serial one-thread-per-chunk Deflate + separate Condense gather with a finer-grained data-parallel deflate: each thread packs a small fixed-size group of symbols (DEFLATE_GROUP_SIZE). Per-group bit sizing + device-side prefix scans (ScanSumExtended) give each chunk's word offset; the pack kernel writes MSB-first directly to each group's final bit offset. Fully-owned output words use plain stores; the <=2 words shared with neighbouring groups are merged with atomicOr (no shared memory, no block/grid cooperation). Serialize is now pure metadata assembly. DEFLATE_GROUP_SIZE=32 (~huff_block_size/32) by sweep. Decompression (Decode): - Register-cache the current packed word, refetching only when the bit cursor crosses a word boundary (was up to one global load per bit). - Cache only the hot first[]/entry[] decodebook tables in shared memory; leave the large keys[] table in global to preserve occupancy. RuntimeX: - Add a portable Atomic::Or to all backends (CUDA/HIP/SYCL/Serial/OpenMP). Config: - huff_block_size 20480 -> 1024 (smaller Huffman chunk: pairs with the finer-grained deflate and improves decode parallelism).

It block-wise delta/zigzag/fixed-length-encodes the quant codes, with three cuSZp-style modes (block_delta_mode_type): Fixed (FLE only), Delta (per-block delta + FLE), and Outlier (Delta + per-block outlier peeling). Default mode is Delta. Architecture: - One unified BlockDeltaLossless class; a compile-time DeviceType branch picks a fused single-kernel path on CUDA/HIP (decoupled look-back resolves the cross-block byte-offset scan in one launch) and a portable multi-kernel path (ScanSumExtended) on SERIAL/OpenMP/SYCL. Outlier mode uses the portable path on all backends. Both paths share one byte layout, so streams are cross-compatible across backends. - Compute/memory stages are separated like the other backends: Compress runs only kernels (packs in place, bit-widths to workspace); Serialize does the metadata Copy1D; Deserialize sets pointers; Decompress runs only kernels. This lets the lossless stage overlap with the pipeline's memory movement. Integration: - Quantizer leaves raw signed codes for BlockDelta (no dictionary shift / outlier separation), via the existing prep_huffman toggle. - ComposedLosslessCompressor only sizes the Huffman workspace when the configured backend actually uses it (fixes a divide-by-zero when a non-Huffman backend left huff_block_size unset), and InitializeConfig no longer overwrites config fields with zero-valued metadata. - Persisted in the metadata (proto Encoding::X_BLOCK_DELTA + block_delta_block_size); the encoding mode is self-describing in the BlockDelta stream header. - CLI: -l blockdelta[-fixed|-delta|-outlier]; Config gains block_delta_block_size and block_delta_mode. Tests: tests/mgard-x/src/test_BlockDelta.cpp.in round-trips all three modes (plus an all-zero edge case) on each enabled backend.

drop nvcomp dependency Replace the nvcomp-backed LZ4 with a portable, nvcomp-free LZ4 lossless backend (Lossless/LZ4/). A single cooperative codec is written once against a new portable sub-group abstraction and lowered per backend: * SubGroup / SubGroupScalar live in the DeviceAdapters (7 primitives: size/lane/full_mask/shfl/ballot/ffs/sync), so any future cooperative kernel can reuse them. * CUDA: warp-per-chunk with a shared-memory hash table and warp-parallel match scan + cooperative byte copy. On NYX/H100 this matches or beats nvcomp LZ4 on both compress and decompress at equal compression ratio. * SERIAL/OpenMP: size-1 sub-group, so the same code degenerates to the plain serial encoder/decoder (CPU parallelism stays at the grid level). * HIP and SYCL sub-group specializations are provided but UNTESTED (no AMD or Intel hardware available); they share the same codec. lossless_type: Huffman_LZ4 now uses the portable LZ4; add a standalone LZ4 (LZ4 applied directly to the raw quantized stream, no Huffman). Removed the nvcomp LZ4 class and the never-wired-in Bitcomp/Cascaded wrappers (dead code, no CR/speed value, and the last nvcomp users in mgard-x). Drop the nvcomp dependency from the mgard-x CUDA build (find_package + link), kept only under MGARD_ENABLE_LEGACY_CUDA; libmgard.so no longer links nvcomp. DeviceAdapterSerial: replace std::inclusive_scan/exclusive_scan with hand-rolled serial scans so the header parses under nvcc's default host compiler (older libstdc++ gates the C++17 algorithms). proto: X_HUFFMAN_LZ4 now denotes the portable Huffman+LZ4 stream; add X_LZ4; reserve the old portable-variant tag. Tests: LZ4 round-trip and composed Huffman+LZ4 now build and run on every backend.

Backends (selectable via -l): - symbol-rans: reuses Huffman's outlier separation + dict_size histogram, then entropy-codes the primary symbols with rANS. On the same model rANS is always <= Huffman (no integer-code-length rounding) and uncapped. On NYX/Miranda it matches or beats Huffman CR everywhere (up to ~4.7x at loose tolerances) and decompresses faster; compress is ~1.7x slower (the entropy-coder tradeoff). - zerorle-rans: zero-RLE (RLE0) of the quantized stream feeding a byte-alphabet rANS (kept as a building block; loses to symbol-rans on real data). Components: - rANS/: byte- and symbol-alphabet static rANS (reciprocal-multiply encode, reused shared-memory histogram, interleaved segment streams). Portable -- only mgard-x abstractions, no raw backend intrinsics. - rANS/RansInterleaved.hpp: warp-cooperative coalesced encode written against the portable SubGroup abstraction. NLANES=32 is a fixed logical/format constant, so the bitstream is hardware-independent; a width-W subgroup processes W/32 logical blocks (CUDA 32-lane warp -> 1 block, AMD CDNA 64-lane wavefront -> 2), with a sequential reference fallback for other subgroup sizes. - ParallelRLE/Zero*.hpp: parallel zero-run-length (RLE0) codec. Wiring & fixes: - lossless_type::{SymbolRans,ZeroRLE_Rans} in ComposedLosslessCompressor, CLI options, and protobuf/Metadata mapping so compress<->decompress round-trips through files. - Config.cpp: default CUDA_MODULE_LOADING=EAGER (overridable) via an early constructor. Lazy loading was pulling the new rANS kernels from the large fatbin on first launch, adding ~0.3s/run to a single compress; eager loading front-loads once and drops the pipeline ~4-5x, with no change for other backends. Tests: test_Rans (byte + interleaved round trips), test_ZeroRLE.

Bump both to the newest releases that declare a CMake minimum >= 3.5 and remain self-contained: - zstd v1.5.0 -> v1.5.6 (declares 3.5) - protobuf v3.19.4 -> v3.21.12 (declares 3.5; last release before the v22.x Abseil/utf8_range dependency) Both bumps validated end-to-end on H100 (CUDA 12.4, gcc 8.5): all deps build, MGARD configures/compiles/links against them, no policy override needed.

Replace these with C++ exceptions that are translated into compress_status_type failure codes at the pipeline boundary, so callers can handle failures gracefully. - Add mgard_x::Exception hierarchy (InvalidDataException, ProcessingException) carrying a compress_status_type. - Wrap general_compress/general_decompress pipelines in try/catch that return a status code instead of letting exit()/exceptions escape. - Convert exit() sites in Metadata deserialization, the Zstd/CPU lossless CHECK macros, Huffman codebook generation, the CUDA/HIP/Kokkos device error checks, and the MDR bitplane encoders/reconstructor.

For shapes that are not multiples of 8, 8x8x8 blocks straddling the boundary mixed uninitialized buffer contents into their coefficients. memset the level-0 fine buffer when padding is needed; deeper levels are unaffected because their fine buffer is a coarse buffer that is already fully memset before use.

Replace these with ProcessingException, which the general_compress/general_decompress try/catch translates into a compress_status_type failure code so callers can handle failures gracefully. - HybridHierarchyDataRefactor: "Both L and M cannot be zero" in Adapt, Decompose, Recompose (also include Exceptions.h directly, since this header only reached log:: via RuntimeXPublic.h, which does not pull in Exceptions.h). - HybridHierarchyLinearQuantization: same "Both L and M cannot be zero" checks in the constructor, Adapt, Quantize, and Dequantize. - LocalQuantization: "Only L-inf supported" in the quantizer setup and the Quantize/Dequantize entry points. Verified on H100 (CUDA sm_90 + SERIAL): full build, 72/72 mgard-x unit tests pass, and the -hh hybrid pipeline runs end-to-end on both backends.

Upload the tolerance map to device once in SetBlockTolerances, and add a small device kernel (ComputeROIQuantizersKernel) that derives the per-block quantizers directly on device from the resident tolerance map, removing the host recompute and the per-call H2D transfer. The existing prep_huffman / huff_dict_size handling in the ROI quantize path is kept. Ported from MasterVChicken/MGARD@04092c47. Measured on an H100 (NYX 512^3 temperature, ROI hybrid -ll 1 -gl 2): the "Local Quantization with ROI" stage drops from 2.60ms to 0.80ms (3.26x) and "Local Dequantization with ROI" from 2.46ms to 0.79ms (3.10x); compression ratio, compressed size, PSNR and 100% ROI block-tolerance satisfaction are unchanged.

Changed to MGARDX_CONT, matching every other functor in the codebase. - Profile the "lwqzk"/"decode" AutoTuner launch configs on real MI300 hardware via mgard-x-autotuner (previously untested placeholders). - DeviceSpecification now reports the true hardware wavefront size (64 on CDNA) instead of a forced 32, and Histogram/GenerateCL are made wavefront-size-agnostic (reading DeviceRuntime::GetWarpSize() at kernel launch and threading it through as a functor member) instead of assuming the CUDA-oriented MGARDX_WARP_SIZE=32. GenerateCL's merge-path search uses shared memory with explicit sync between operations rather than warp-implicit shuffle/ballot, so it's safe to size to the real wavefront; this roughly doubles the per-block search width on MI300 and measurably speeds up Huffman codeword-length generation with no correctness regressions (full HIP test suite still passes, 1,144,598 assertions). - Add a -w/--warm-up CLI flag to mgard-x: HIP pays a one-time per-kernel cold-start cost (lazy code-object loading) that fully lands on whichever pipeline stage happens to launch a given kernel template first. Stages launched many times per compress() call amortize it away; single-shot stages (quantization, most Huffman kernels) previously paid it in full, making them look far slower than they actually are. The flag runs a throwaway compress+decompress on a small array first so real timing reflects steady-state performance.

The coefficient path was five global-memory passes for what is one elementwise operation. Add a fused DecomposeQuantize path that quantizes the 387 per-block coefficients while they are still in shared memory and writes the symbols (Huffman dictionary shift included) straight to their final location in the quantized array: - DecomposeQuantize8x8x8Kernel derives from the unfused functor and overrides only the load (bounds-checked, so unpadded inputs are read directly and the padding memsets/copies disappear) and the store (quantize on write-out). The coarse output stays in T, and the last level writes it compacted to the front of the decomposed array, removing the coarsest staging copy. - Per-level scalar quantizers map decompose level l to quantizer index L-l; in ROI mode the per-block quantizers are indexed by the kernel's block id, which matches the idx/387 mapping of the unfused ROI kernel. The coarsest region is handled as before: global decompose + global quantize when M > 0, a coarsest-layer quantization otherwise. - Compress() takes the fused path when L > 0, D == 3 and s == inf, and falls back to Decompose()+Quantize() otherwise. Setting MGARD_X_DISABLE_FUSED_DECOMPOSE_QUANTIZE forces the unfused path for A/B comparison. The compressed format and the decompression path are unchanged. Verified on 11 configs (L/M combinations, float/double, abs/rel, huffman/zstd, ROI, non-multiple-of-8 shapes): byte-identical output on SERIAL; equal compressed size and byte-identical decompressed output on CUDA (the CUDA stream is not run-deterministic due to outlier append order). On an H100 with NYX temperature 512^3, decompose+quantize runs 1.5-1.9x faster and the low-level compression kernel time drops 20-40%.

In the hybrid compressor, the quantized coefficients used to be expanded by a separate dequantization kernel into the T-typed decomposed array, which the recompose kernels then read back -- plus the unfused Recompose staged the coarsest level through temp_coarest, memset both ping-pong buffers in full, and copied the final level into the output with CopyND. The coefficient path was three global-memory passes for what is one elementwise operation, plus three staging copies. Add a fused RecomposeDequantize path that dequantizes the 387 per-block coefficients while staging them into shared memory, reading the symbols (Huffman dictionary shift removed) straight from their location in the quantized array: - RecomposeDequantize8x8x8Kernel derives from the unfused functor and overrides only the coefficient load (dequantize in-register, exactly matching QuantizeLocalLevelFunctor's DEQUANTIZE arithmetic) and the store (bounds-checked, so the last level writes directly into the unpadded output and the final CopyND disappears). The coarsest level is read compactly in place from the front of the decomposed array, removing the temp_coarest restore copy; the buffer memsets are dropped because every coarse value read at level l is covered by level l+1's write (or comes from the decomposed array). - Per-level scalar dequantizers map decompose level l to quantizer index L-l (non-reciprocal); in ROI mode the per-block dequantizers are indexed by the kernel's block id, matching the idx/387 mapping of the unfused ROI kernel. The coarsest region is handled as before: global dequantize + global recompose when M > 0, a coarsest-layer dequantization otherwise. - Unlike the compress side, the high-level pipelines do not call Decompress(); they invoke Dequantize() and Recompose() stepwise, so the dispatch lives in a shared DequantizeRecomposeStep() helper (FusedDequantizeRecompose.hpp) used by both GPUPipelines and CPUPipelines. It takes the fused path when the compressor provides one and L > 0, D == 3 and s == inf, falling back to Dequantize()+Recompose() otherwise. Setting MGARD_X_DISABLE_FUSED_DEQUANTIZE_RECOMPOSE forces the unfused path for A/B comparison. The compressed format and the compression path are unchanged. Verified on 11 configs (L/M combinations, float/double, 500^3 non-multiple-of-8 shapes, huffman-zstd, ROI): byte-identical decompressed output fused vs unfused on both SERIAL and CUDA (A100). On an A100 with NYX 512^3 float fields, the decompression kernel time (lossless decode + dequantize + recompose) drops by a geomean 1.13x (huffman 1.16x, blockdelta 1.10x); compression is unaffected. The prior kernel work gained noticeably more on sm_90 than sm_80, so the Hopper numbers are expected to be higher (pending -- hopper1/illyad are both down).

Everything needed to reverse it -- the local and global refactoring level counts, which fix the layout of the decomposed buffer and decide which (de)quantizers run, and the ROI tolerance map, which fixes the per-block quantization step -- lived only in the caller's Config. Since InitializeConfig never touched those fields, decompressing meant re-supplying the exact compression parameters by hand (mgard-x -x -ll .. -gl .. -roi -r), and getting them wrong produced silently garbled output rather than an error. Add a HybridHierarchy message under FunctionDecomposition carrying the level counts, the block-local transform block size, and an optional RegionOfInterest holding the level-0 per-block tolerances (deeper levels are re-derived on read exactly as the compressor derives them). ROI maps are piecewise constant in practice, so the tolerances are written run-length encoded when that is smaller and packed otherwise; both decode bit-exactly, which matters because the values are quantization steps. Also record the quantized integer width instead of hardcoding INT64_T. The read side asserted on it, so the check vanished in release builds; it is now a real check that reports a clean mismatch. Recording the width is what makes changing QUANTIZED_INT later a compatible operation rather than one that turns existing files into garbage. A hybrid file written before this carries no hybrid_hierarchy field and is now rejected with an explanatory error, which is the point: falling back to the Config defaults is what produced wrong output without any error. MGARD_FILE_VERSION_MINOR goes to 1. On the CLI, -ll/-gl/-roi/-r become optional overrides on decompress, so a plain "mgard-x -x -i f.mgard -o f.raw" now round-trips a BlockMGARD file. The -orig block-error report is decoupled from them and keyed on -orig plus -r. ROI combined with domain decomposition is left as it was (each subdomain indexes the flat map from offset 0, so the tolerances do not line up) but now warns; the map is still recorded verbatim, so files round-trip exactly as compressed. Verified on H100 (CUDA sm_90 + SERIAL): 163/163 ctest, and hybrid files compressed with -ll 2 -gl 1 and with ROI both decompress correctly with no flags on either backend.

That was bridged by a SFINAE trait plus a dispatch function in a header of its own, FusedDequantizeRecompose.hpp, which the pipelines called instead of the compressor: capability detection standing in for an interface. Make it an ordinary method instead. Compressor and zfp::Compressor get a DequantizeRecompose that runs the two existing calls in sequence; HybridHierarchyCompressor overrides it to pick between its fused single-pass implementation (now spelled DequantizeRecomposeFused) and the two-step path. The pipelines just call compressor.DequantizeRecompose(), matching how they already call LosslessDecompress() next to it, and the trait and its header are gone. Two things fall out of this. The choice between fused and unfused was being made in three places -- the dispatch shim, Compress()'s dry-run branch, and Decompress() -- and is now made once, in the override. And the shim's fallback called Recompose(data, true, queue), which does not compile against zfp::Compressor::Recompose(data, queue); that only went unnoticed because MGARD_ENABLE_EXTERNAL_COMPRESSOR defaults to off. Each compressor now spells out its own sequence, so the signatures no longer have to agree. The zfp path is still not compile-tested here for the same reason. No behavior change. Verified on H100 (CUDA sm_90 + SERIAL): 171/171 ctest.

The unfused two-pass path is still there and still wanted, so keep it selectable. It already was, through two environment variables, but only barely: the reads were four copies of getenv() spread across three files, each cached in a function-local static. Caching meant the value was fixed at first use, so setenv() from an embedding application did nothing and a test process could not exercise both paths. Collect them into Utilities/KernelFusion.h and read per call -- that is one getenv per Compress()/Decompress(), not per element. MGARD_X_DISABLE_FUSED_DECOMPOSE_QUANTIZE=1 (compression) MGARD_X_DISABLE_FUSED_DEQUANTIZE_RECOMPOSE=1 (decompression) Both default to fused, are independent, and are documented in --help. This stays an environment variable rather than a Config field on purpose: it does not describe the data, nothing about it is recorded in the header, and either path decompresses the other's output. Log the branch actually taken, from inside the branch, and say why when it is not fused -- "no block-local levels", "fused kernel is 3D only", "fused kernel requires s = inf", or that the variable is set. Fusing needs L > 0, D == 3 and s == inf, all read from the file, so the unfused path runs for plenty of inputs with no variable set; logging the variable alone (which is what the high-level pipeline did) reported "fused" for runs that were not. The test asserts what the two paths actually guarantee -- each meets the requested tolerance, all four fuse combinations meet it, and the compressed size stays within 1% -- not that they agree bit for bit. They do not, and neither backend is even reproducible against itself: on GPU the Huffman outlier separator assigns slots with block-aggregated atomics, so outlier order follows block scheduling; on CPU the result depends on memory layout, where a 4 KB change in the size of the environment block moves the compressed size of a 64^3 float input by 424 bytes.

That choice was reachable only through two environment variables. Make it a command-line flag: -nkf / --no-kernel-fusion Accepted in both -z and -x, turning off fusion in whichever direction the invocation runs. Fusion stays on by default, and --help lists the flag alongside -hh, -ll and -gl. Config gains fuse_decompose_quantize and fuse_dequantize_recompose, both defaulting to true, which the executable sets from the flag and the compressor reads at the branch. The two directions stay separate in Config so the tests can drive them independently -- that is how the fused and unfused paths are checked against each other -- while the command line exposes a single flag, since compression and decompression are already separate invocations of the tool. Nothing about the choice is recorded in the file header. Both paths reconstruct identically, so a file compressed either way still decompresses either way. MGARD_X_DISABLE_FUSED_DECOMPOSE_QUANTIZE and MGARD_X_DISABLE_FUSED_DEQUANTIZE_RECOMPOSE are gone, along with Utilities/KernelFusion.h that held them, and the "why not fused" log line no longer names them. The test drops the setenv/unsetenv wrapper it used to put around each round trip and sets the two Configs it was already building.

CMakeLists.txt now requires find_package(HIP 7.0) so this fails fast at configure time instead of deep into a HIP compile. Also drop every build script's explicit -DMGARD_ENABLE_SERIAL=ON/OFF. MGARD_ENABLE_SERIAL already defaults to ON, and RuntimeX.h hard #errors if it's ever off ("The serial MGARD device should always be available."), so the several scripts passing =OFF (including the HIP/Frontier one) were carrying a latent build break. Removing the flag everywhere lets the default -- and the CMakeLists.txt SYCL branch that force-disables it when MGARD_ENABLE_SYCL is on -- be the only source of truth. Verified end to end on Frontier (MI250X, ROCm 7.2.0): full mgard-x ctest suite (90/90) passes on both the serial and hip backends.

A wider stride is harmless on its own -- indexing through it is self-consistent and stays inside the allocation. The corruption comes from there being two strides for one buffer: BlockLocalHierarchyDataRefactor builds one view from the array itself (SubArray(coarse_buffers[1]), which picks up the stale ld) and others by hand (setLd(d, fine_shapes[0][d]), which assumes a dense layout). Once those disagree, one view writes rows at a stride the other does not read them at. Reached through CompressorCache, whose device_subdomain_buffer is resized per call, this silently corrupted the public compress()/decompress() API whenever a second, differently-shaped dataset was processed in the same process: Success returned, an ordinary-looking compression ratio, and data uncorrelated with the input. Only the innermost stride changes the addressing here, so shrinking just the slowest-varying dimension happened to survive, which made the failure look arbitrarily shape-dependent. The bug reached the public API because nothing tested it, and nothing tested the layers under it directly either. Add coverage at each level so a regression localises instead of surfacing end to end. test_DataRefactoring drives in_cache_block::decompose/recompose directly rather than through BlockLocalHierarchyDataRefactor, which chains levels. Round-trip identity; a constant field, which the multilinear interpolant reproduces exactly, so every coefficient must vanish; fused vs unfused agreement asserted exactly (the coarse brick bit-identical, coefficients equal to a host mirror of the in-kernel quantizer, the fused inverse bit-identical to the unfused one), with prep_huffman both ways; and the fused path's bounds-checked handling of unpadded shapes against the unfused path on zero-padded input. The round-trip error is bounded against the quantization half-bin rather than a round number, since recompose is linear and the measured gain is ~1.55. test_HybridHierarchy asserts that Decompose/Recompose equal the local stage plus DecomposeGlobal/RecomposeGlobal -- entry points only the fused quantization path calls, so drift between them would desynchronise the fused and unfused compressors. Recompose through a second, independently Adapted refactor, matching how decompression actually runs. The global hierarchy's shape against an independently computed ceil(n/8)*5 per level. The L == M == 0 guard. And the public pipeline: a default-Config decompress, so the hybrid level counts have to come back from the metadata header; decompress with a deliberately wrong Config giving identical output; hybrid vs standard streams differing while both honour the bound; and two differently-shaped datasets back to back, which is the case that caught the resize bug.

Neither showed up in CI: CompressionHighLevel.hpp only includes this header under `#if MGARD_ENABLE_OPENMP`, and the CUDA builds do not enable OpenMP, so the file has not been parsed since February 2025. Both fixes match GPUPipelines.hpp, which has the correct form in all three places: the restored signature is identical to compress_pipeline_gpu's, and total_size is hoisted to where the GPU twin computes it.

Add the 1D (8) and 2D (8x8) transforms and dispatch on D; the 3D path is untouched. IndexTable8x8x8.hpp spells out every table entry by hand, which is impractical to repeat twice more. The block geometry is per-dimension identical -- 8 fine nodes coarsen to {0, 2, 4, 6, 7}, with the trailing cell split around a phantom node at 6.5 -- so IndexTableLowDim.hpp states those rules once as constexpr builders and lets the compiler expand them. The rules were checked against the hand-written 3D tables first: they reproduce the mass-transform X stencils (including the coarse-node masking), Y, Z, the coefficient ordering, the coarse ordering and the tridiagonal lines exactly. am/bm and the mass-transform weights are shared with the 3D block rather than duplicated, since the coarse spacing {2, 2, 2, 1} is a per-dimension property. A 1D block is far too little work for a thread block, so the 1D kernels pack 32 tiles per block with per-tile shared-memory strides; 2D uses one 8x8 tile per 64-thread block. Elsewhere the coefficient count per block becomes 8^D - 5^D (hybrid_local_coeff_per_block) instead of a hardcoded 387, which is how the ROI per-block quantizers are addressed, and the fused path no longer refuses D != 3. Tests cover 1D and 2D round trips, hybrid refactoring, the compressor and the end-to-end pipeline, padded and unpadded, fused and unfused -- that last split was previously untested at any D. A new multilinear-exactness case pins the forward transform on its own: interpolation is exact for multilinear data, so every coefficient must be zero and every coarse value must equal the input, which a round trip cannot see because a symmetric index or sign slip round trips fine.

The ROI local quantizer walks only the L coefficient layers, from the end of the array; layer 0 sits at the front. The non-ROI path compensates with `start_level = (M > 0) ? 1 : 0`, and the fused path guarded its coarsest-layer call with `else if (!config.enable_roi)`. Neither covered ROI with M == 0, and with M > 0 the global stage hid the gap. It also hid in testing, because a compress immediately followed by a decompress in the same process reads the coarsest layer out of the still-live decomposed buffer -- so mgard-x -z reported "All blocks satisfied their tolerances" while decompressing the file in a separate process returned zeros in 1D and ~1e-3 garbage in 3D. Quantize layer 0 with a scalar quantizer in ROI mode too, using the tightest tolerance among the coarsest blocks -- the value the global stage is handed when M > 0, so both configurations treat that layer consistently. The quantizer math already agreed: the ROI kernel and CalcQuantizers compute the same expression, and layer 0 is simply the term the ROI map never covered. The test uses two compressor objects held alive at once, so their buffers are distinct live allocations. release_cache() is not enough on its own -- the allocator can hand the replacement the same buffers, and a version of this test that relied on it passed against a deliberately broken build. Reverting the fix and rebuilding now fails 8 of 16 assertions for both float and double, and the surviving 8 are exactly the M > 0 sections, where the bug cannot apply.

HuffmanWorkspace sized the array from an unrelated occupancy estimate, (GetMaxNumThreadsPerTB() / GetWarpSize()) * GetNumSMs(), so whenever the dictionary needed more blocks than the device was estimated to run at once the kernel wrote off the end of the allocation. OpenMP hit it because GetNumSMs() there returns omp_get_num_threads(): at one thread the estimate is 32 blocks, giving 66 uint32 entries where dict_size 8192 needs 514. HIP was under-sized too -- the workspace used GetWarpSize() (64) while GenTask overrides the block width to 512, an 8x shortfall at large dictionaries. A real GPU reports enough SMs that CUDA never overflowed, which is why this went unseen. The corruption was silent: the kernel's own results were unaffected and the tests' assertions passed, with glibc only aborting later in Catch2's singleton teardown ("munmap_chunk(): invalid pointer"), or segfaulting, or hanging. Nothing caught it because the CUDA CI does not enable OpenMP and any GCC 8 build aborts earlier on the ScanSum GCC 9+ guard, before reaching this code. Give the block width and the required size one definition on GenerateCLKernel and have both GenTask and all three HuffmanWorkspace sites use it -- the duplicated arithmetic is what let the two drift apart. The old occupancy value is kept as a floor, so no device gets a smaller allocation than before. Verified with GCC 13 + OpenMP, which is the first configuration able to run these tests at all: valgrind goes from 9 invalid reads/writes to 0 errors, the 18 previously crashing hybrid tests all pass, and the crash/no-crash boundary across thread counts lands exactly where the sizing arithmetic predicts.

Add the s != inf branch, using the same per-level law as LinearQuantizer: step_l = abs_tol / (2^(s*l) * sqrt(dof)) LinearQuantizer also scales each value by its node volume, read from a per-node level_volumes array, which the block-local kernels cannot do -- they take one scalar per layer. They do not need to: Hierarchy::calc_volume fills that array with total_dist / (dof - 1), the average spacing, identical for every node of a level. The volume is therefore a per-level constant and folds into the scalar exactly, matching the kernels' quantize/dequantize convention so the pair still round-trips. That also keeps kernel fusion available for s != inf: the fused kernels already take a scalar quantizer per level, which is all the s-weighting is. ROI stays L-inf only, as its per-block quantizers have no s-norm formulation: CanFuseQuantize now refuses ROI with s != inf, and the ROI quantize and dequantize entry points keep their existing guard. compute_local_ranges was overwriting coarse_shape each iteration and keeping only the final value; it now records the per-level fine and coarse shapes, which the volume needs. Tested by asserting the contract itself -- achieved L_2 error under the requested tolerance, the metric test_Compressor uses for s != inf -- across 1D/2D/3D, with and without a global stage, one and two local levels, padded shapes, fused and unfused, REL and ABS. The bound is not met vacuously: at rel 1e-3 on 64^3 the L2 mode reaches CR 9.59 against 5.35 for L-inf and 10.70 for the non-hybrid pipeline, using about 45% of the error budget. Two choices here are conservative rather than derived from the s-norm theory: ErrorBudgetAllocation still splits the global stage's tolerance by 2^L, and block-local layer indices are not offset by the global level count. Both hold empirically in the cases above, including with a global stage.

With one local level each 8^D block is transformed independently, so the total squared error is a plain sum over blocks and the budget divides evenly in quadrature -- tol / sqrt(num_blocks) per block -- exactly as calc_local_abs_tol does across subdomains for domain decomposition. A second local level mixes the coarse outputs of neighbouring blocks, and a global stage decomposes across blocks outright; in both cases the blocks stop being independent and the sum no longer bounds the error. The quantizer already divides the budget that way without knowing it: dof is num_blocks * 8^D, so abs_tol / sqrt(dof) is (abs_tol / sqrt(num_blocks)) / sqrt(block_dof). This commit is what makes that division sound rather than incidental. The public compress path falls back to L = 1, M = 0 and warns, rather than refusing a request it can still serve. The adjustment happens right after config.apply(), before the DomainDecomposer sizes subdomains and before the level counts are written to the file header, so the decompressor reads back what was actually used. The low-level quantizer cannot fall back -- L and M fixed the buffer layout back at Adapt() -- so it throws from all four entry points instead of returning a result it cannot bound. L-inf is untouched: its bound composes over levels and needs no independence, so multi-level local and the global stage still work there. Both warnings pass override = true. log::warn is gated on log::WARN, which verbose_to_log_level never sets at any verbosity, so an ordinary warning here would never reach the user -- and silently changing the configuration someone asked for is exactly what must stay visible. Tested: the bound holds at L = 1, M = 0 across 1D/2D/3D, padded and non-cubic shapes, fused and unfused, REL and ABS; the low-level path throws for (2,0), (1,2) and (2,1) and not for (1,0); and the public path takes hybrid_config(2,2) with s = 0, falls back, round trips through the header and still satisfies the L2 bound.
