||
|
||
### Added
|
||

|
||
|
||
### Changed
|

|
||
- Align memory to 2MB pages in RAJA and OpenMP.
|
||
- Updated Intel compiler flags for OpenMP, Kokkos and RAJA to ensure streaming stores.
|
||

|
||
- Use static shared memory for dot kernel in CUDA and HIP.
|
||
|
||
### Fixed
|
||

|
||
|
||
|
||
## [v3.1] - 2017-02-25
|
||
|
||
### Added
|
||
- Dot kernel HIP implementation.
|
||
|
||
### Changed
|
||
- Build system overhauled from CMake to a series of Makefiles.
|
||
|
||
### Deprecated
|
||
- Android build instructions.
|
||
|
||
|
||
## [v3.0] - 2017-01-30
|
||
|
||
### Added
|
||
- New Dot kernel added to the 4 standard kernels.
|
||
|
||
### Changed
|
||
- All model implementations now initialise and allocate their own arrays rather than copying from a master copy. This allows for better performance on NUMA architectures.
|
||
- Version string definition moved from header to main file.
|
||
- Combined OpenMP 3 and 4.5 implementations.
|
||
- OpenMP 4.5 target implementation uses alloc instead of to.
|
||
- Made SYCL indexing consistent.
|
||
- Update SYCL CMake build to use ComputeCpp CE 0.1.1.
|
||
|
||
### Fixed
|
||
- OpenMP deconstructor now only frees GPU memory only on GPU build.
|
||
- SYCL template specializations for float and double.
|
||
|
||
|
||
## [v2.1] - 2016-10-21
|
||
|
||
### Added
|
||
- New HIP version added.
|
||
- Results for v2.0 added.
|
||
- Output of OpenCL kernel build log on failure.
|
||
|
||
### Changed
|
||
- Use globally defined scalar value.
|
||
- Change scalar value to stop overflow.
|
||
- Restructure results directory.
|
||
- Change SYCL default work-group size.
|
||
- CMake defaults to Release build.
|
||
|
||
### Fixed
|
||
- CUDA device name output string corrected.
|
||
- Out of tree builds.
|
||
|
||
|
||
## [v2.0] - 2016-06-30
|
||
|
||
### Added
|
||
- Implementations in OpenMP 4.5 OpenACC, RAJA, Kokkos and SYCL.
|
||

||
- Runtime option variables are printed out.
|
||
- Device selection added to OpenCL and CUDA.
|
||
|
||
### Changed
|
||
- Major refactor to include multiple programming models. The change now uses C++ for driver code, with different models plugged in as classes which implement the STREAM kernels.
|
||
- Starting values in the arrays to reduce floating point errors with high iteration counts.
|
||
- Default array size now 2^25.
|
||
- Default to 100 iterations instead of 10.
|
||
- CUDA thread block size set via define rather than hardcoded value.
