From 11140547e8a58d52cd316b0a3adb4c6ec9de5b70 Mon Sep 17 00:00:00 2001 From: Jeff Daily Date: Thu, 25 Jun 2026 21:10:30 +0000 Subject: [PATCH] [ROCm] Add a HIP backend (PSZ_BACKEND=HIP) targeting ROCm This adds AMD GPU support to pSZ/cuSZ as a third backend, PSZ_BACKEND=HIP, alongside the existing CUDA (default) and ONEAPI backends. It builds the same device logic on ROCm; the CUDA and oneAPI backends are unchanged. Rather than maintaining a separate set of .hip sources, the HIP backend reuses the existing .cu/.cu.inl/.cc translation units, compiled with LANGUAGE HIP, through the portable/include/macro/c_cu2hip_* translation macros plus a small cmake/hip-compat/ force-include shim (cuda_runtime/cuda/cuda_fp16/ cooperative_groups/curand -> hip/hiprand). A new cmake/hip.cmake mirrors cmake/cuda.cmake, and PSZ_BACKEND=HIP is wired into the top-level CMake and each sub-project (portable, codec/hf, codec/fzg, utils, psz). Suggested review order: the CMake wiring (CMakeLists.txt, cmake/hip.cmake) and the cmake/hip-compat/ shims first; then the portable layer (the _ptb_runtime::HIP enumerator in c_type.h, the HIP branch in mem/cxx_backends.h, the variadic warp-shuffle macros, the event/stream handles); then the two wavefront-width corrections; then verinfo_hip.cu and the utils kernels. Two correctness fixes to wavefront-width assumptions, so results are consistent on wave32 (RDNA) and wave64 (CDNA): the warp-ballot translation now selects the correct 32-bit half of the ballot result by the lane's wavefront-half base rather than truncating to the low 32 bits; and the AMD intra-warp scan in the HistSp histogram (histsp.cu.inl) now uses the physical wavefront width rather than a hardcoded width of 64. The CUDA path is unchanged. On the HIP path cuRAND maps to hipRAND; the NVML/CUPTI-based device-info and profiling paths are not built; no textures/surfaces and no cuBLAS/cuFFT are used. The bundled LC-framework (third_party/lc) is left disabled on HIP (PSZ_ACTIVATE_LC defaults OFF); the core Lorenzo/spline + Huffman/HFR + FZG pipeline is unaffected. The HIP architecture is auto-detected from the GPUs on the build machine; set CMAKE_HIP_ARCHITECTURES only to target a different or non-local GPU. New HIP source files carry a parallel AMD copyright line below the existing upstream copyrights and credit the porting author; upstream copyrights are preserved. Authored with assistance from Claude (an AI assistant). Test Plan: Build the HIP backend (architecture auto-detected; ROCm 7.2.1): ``` cmake -B build -DPSZ_BACKEND=HIP -DCMAKE_PREFIX_PATH=/opt/rocm cmake --build build -j ``` Run the test suite on an AMD GPU: ``` cd build && ctest --output-on-failure ``` Built and run on gfx90a (MI250X, CDNA2), gfx1100 (Radeon RX 7900 XTX, RDNA3), and gfx1201 (Radeon RX 9070 XT, RDNA4). The portable unit tests, the GPU unit tests, and the bin_hf HFR/FZG codec matrix pass; the cusz CLI round-trip matrix (Hurricane ISABEL and NYX) passes with a compression ratio matching the CUDA backend (CR=27.04 on the shared reference). The CUDA and oneAPI backends build and behave as before. --- CMakeLists.txt | 18 +- README.md | 2 +- cmake/hip-compat/cooperative_groups.h | 8 + .../cooperative_groups/memcpy_async.h | 9 + cmake/hip-compat/cuda.h | 9 + cmake/hip-compat/cuda_fp16.h | 7 + cmake/hip-compat/cuda_runtime.h | 17 + cmake/hip-compat/cuda_runtime_api.h | 9 + cmake/hip-compat/curand.h | 18 + cmake/hip-compat/psz_hip_compat.h | 22 ++ cmake/hip.cmake | 349 ++++++++++++++++++ cmake/probe.cmake | 4 + codec/fzg/CMakeLists.txt | 32 +- codec/hf/CMakeLists.txt | 39 +- codec/hf/src/hf_buf.cc | 9 +- example/CMakeLists.txt | 2 + example/cmake/hip-example.cmake | 25 ++ portable/CMakeLists.txt | 37 +- portable/include/c_type.h | 2 +- portable/include/cxx_typing.h | 4 + .../include/macro/c_cu2hip_0_translation.h | 14 +- .../include/macro/c_cu2hip_1_fix_primitives.h | 29 +- portable/include/mem/cxx_backends.h | 43 +++ portable/include/mem/cxx_mem_ops.h | 4 + portable/include/mem/gpu_event.hh | 29 +- portable/include/mem/gpu_stream.hh | 7 +- portable/include/utils/err.hh | 4 + psz/src/cli/context.cc | 6 + psz/src/cli/query/query_cpu.hh | 6 + psz/src/cli/verinfo_hip.cu | 92 +++++ psz/src/compressor.inl | 2 +- psz/src/kernel/histsp.cu.inl | 11 +- psz/src/kernel/spl_y24.cuh | 3 +- test/CMakeLists.txt | 10 +- test/cmake/cuda-test.cmake | 68 +++- utils/CMakeLists.txt | 66 +++- utils/include/compare.hh | 10 +- utils/src/atomics.cu.inl | 4 +- utils/src/extrema.cu.inl | 14 +- utils/src/viewer.cc | 16 +- 40 files changed, 977 insertions(+), 83 deletions(-) create mode 100644 cmake/hip-compat/cooperative_groups.h create mode 100644 cmake/hip-compat/cooperative_groups/memcpy_async.h create mode 100644 cmake/hip-compat/cuda.h create mode 100644 cmake/hip-compat/cuda_fp16.h create mode 100644 cmake/hip-compat/cuda_runtime.h create mode 100644 cmake/hip-compat/cuda_runtime_api.h create mode 100644 cmake/hip-compat/curand.h create mode 100644 cmake/hip-compat/psz_hip_compat.h create mode 100644 cmake/hip.cmake create mode 100644 example/cmake/hip-example.cmake create mode 100644 psz/src/cli/verinfo_hip.cu diff --git a/CMakeLists.txt b/CMakeLists.txt index b71b3352..c777da70 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -1,9 +1,12 @@ # select backend -set(PSZ_BACKEND "CUDA" CACHE STRING "Select the desired backend: CUDA/cuda and ONEAPI/1api.") +set(PSZ_BACKEND "CUDA" CACHE STRING "Select the desired backend: CUDA/cuda, HIP/hip, ONEAPI/1api.") if(PSZ_BACKEND STREQUAL "CUDA" OR PSZ_BACKEND STREQUAL "cuda") cmake_minimum_required(VERSION 3.18) project(CUSZ LANGUAGES CUDA CXX C VERSION 0.10.0) +elseif(PSZ_BACKEND STREQUAL "HIP" OR PSZ_BACKEND STREQUAL "hip") + cmake_minimum_required(VERSION 3.21) + project(HIPSZ LANGUAGES HIP CXX C VERSION 0.10.0) elseif(PSZ_BACKEND STREQUAL "ONEAPI" OR PSZ_BACKEND STREQUAL "oneapi" OR PSZ_BACKEND STREQUAL "1api") cmake_minimum_required(VERSION 3.23) project(DPSZ LANGUAGES CXX C VERSION 0.6.0) @@ -14,7 +17,15 @@ set(CMAKE_EXPORT_COMPILE_COMMANDS ON) option(BUILD_SHARED_LIBS "prefer shared libaries" ON) # conditionally enable functionality -option(PSZ_ACTIVATE_LC "build LC as a submodule" ON) +# The bundled LC-framework (third_party/lc) is an external CUDA codebase that is +# not yet ported to HIP; default it OFF on the HIP backend so the core +# Lorenzo/spline + Huffman/HFR + FZG pipeline builds.
