-A light-weight mechanism/framework to log input details and a stringified version of the post-ops structure is added to LPGEMM. Additionally the runtime of the API is also logged. The logging framework logs to a file with filename following the format aocl_gemm_log_<PID>_<TID>.txt. -To enable this feature, the AOCL_LPGEMM_LOGGER_SUPPORT=1 macro needs to be defined when compiling BLIS (with aocl_gemm addon enabled) by passing CFLAGS="-DAOCL_LPGEMM_LOGGER_SUPPORT=1" to ./configure. Additionally AOCL_ENABLE_LPGEMM_LOGGER=1 has to be exported in the environment during LPGEMM runtime. AMD-Internal: [SWLCSG-3280] Change-Id: I30bfb35b2dc412df70044601b335938fc9f49cfb
AOCL-BLAS library
AOCL-BLAS is AMD's optimized version of BLAS targeted for AMD EPYC and Ryzen CPUs. It is developed as a forked version of BLIS (https://github.com/flame/blis), which is developed by members of the Science of High-Performance Computing (SHPC) group in the Institute for Computational Engineering and Sciences at The University of Texas at Austin and other collaborators (including AMD). All known features and functionalities of BLIS are retained and supported in AOCL-BLAS library. AOCL-BLAS is regularly updated with the improvements from the upstream repository.
AOCL BLAS is optimized with SSE2, AVX2, AVX512 instruction sets which would be enabled based on the target Zen architecture using the dynamic dispatch feature. All prominent Level 3, Level 2 and Level 1 APIs are designed and optimized for specific paths targeting different size spectrums e.g., Small, Medium and Large sizes. These algorithms are designed and customized to exploit the architectural improvements of the target platform.
For detailed instructions on how to configure, build, install, and link against AOCL-BLAS on AMD CPUs, please refer to the AOCL User Guide located on AMD developer portal.
The upstream repository (https://github.com/flame/blis) contains further information on BLIS, including background information on BLIS design, usage examples, and a complete BLIS API reference.
AOCL-BLAS is developed and maintained by AMD. You can contact us on the email-id toolchainsupport@amd.com. You can also raise any issue/suggestion on the git-hub repository at https://github.com/amd/blis/issues.
