hipThreads 0.1.1 for ROCm 7.12
Added
- Performance testing in CI, including all hipThreads examples (#86).
- Email notifications for CI workflow runs (#61).
Changed
- Install public headers under a
hipthreads/subdirectory (#107). - Use
ROCM_PATHin the top-level CMake build, and in the examples with an/opt/rocmfallback (#107). - Updated
README.md,docs/setup.md, anddocs/index.mdfor ROCm 7.12+ build and install instructions (#107). - Replace
__libcpp_thread_sleep_forwith__cccl_thread_sleep_forfor CCCL 3.0 and newer (#87). - Updated the CPU InOneWeekend Raytracer samples to avoid virtual functions for better performance (#96).
Resolved issues
- Fixed duplicate
hipthreadslinking intest/CMakeLists.txtthat caused device-side duplicate symbol errors (#105). - Applied a placement-new workaround for a ROCm 7.12 compiler bug in the examples (#107).
- Fixed the libhipcxx include path for the CI build on TheRock 7.12 (#76).
hipThreads 0.1.0 for ROCm 7.0.2
Initial early-access technology preview of hipThreads — a C++-style concurrency library that brings std::thread-like primitives to AMD GPUs.
This first release establishes the core library and its supporting infrastructure:
std::thread-style concurrency primitives that run inside GPU kernels:hip::wthread,hip::mutex,hip::lock_guard,hip::condition_variable, and the cooperativepseudo_*variants.- Persistent scheduler kernel with host- and device-side work submission, and multi-fiber (SIMD
width) execution support. - CMake build (native HIP language support), a
lit-based test suite, and a CI/CD workflow. - Example projects demonstrating incremental CPU to GPU ports (saxpy, InOneWeekend Raytracer, sparse matrix multiplication, and llama3.c).
- Initial documentation (
README.md,docs/, and Doxygen configuration).
