ScaLAPACK For AMD

ScaLAPACK, or Scalable LAPACK, is a library of high performance linear algebra routines for distributed memory computers supporting MPI.

ScaLAPACK for AMD is the optimized version of ScaLAPACK for AMD EPYC family of processors.

Building Scalapack for AMD:

1. Install MPI library and set the PATH and LD_LIBRARY_PATH environment variables to point to installed binaries. eg. export PATH=/bin:$PATH eg. export LD_LIBRARY_PATH=/lib:$LD_LIBRARY_PATH

2. Download AMD optimized versions of BLIS and libFLAME from following link https://developer.amd.com/amd-aocl/

3. Install BLIS and libFLAME libraries either using pre-built binaries or build from source. To build BLIS and libFLAME from source, clone from following github links BLIS: https://github.com/amd/blis libFLAME: https://github.com/amd/libflame

4. Provide the Blis and LibFlame libraries' path in the 'SLmake.inc' file. eg. BLASLIB_PATH = eg. LAPACKLIB_PATH =

5. Run the below commands in the Scalapack folder to build Scalapack Library: make clean make

6. To Build and Run the Scalapack test suite, Run the below script: ./scalapack_test.sh Build and Test logs will be generated in 'ScalaPack_Build_log.txt' and 'ScalaPack_TestResults.txt' respectively.
