Migration from OpenBLAS to KML_BLAS

Replaceability

The interface syntax of the KML_BLAS is the same as that of the OpenBLAS.

Migrating the C-based Library

OpenBLAS contains the open-source netlib LAPACK. If only some of the BLAS interfaces are used, perform the following steps:

1. Replace the header file #include <cblas.h> called by the OpenBLAS source code with #include <kblas.h>.
2. Replace -lopenblas with -lkblas in the compilation options.
3. Add environment variables. /PATH_TO_KBLAS is the installation path.

   export LD_LIBRARY_PATH=/PATH_TO_KBLAS:$LD_LIBRARY_PATH

If both the BLAS and LAPACK interfaces are used, perform the migration by referring to .

1. In the compilation options, replace -lopenblas with -lkblas -lklapack.
2. Add environment variables. /PATH_TO_KBLAS_AND_KLAPACK indicates the installation path.

   export LD_LIBRARY_PATH=/PATH_TO_KBLAS_AND_KLAPACK:$LD_LIBRARY_PATH
