High-performance computing

Using the OpenMP/Fortran code generation chain, we have experimented the generated code in a typical operation in the scientific field: the matrix multiplication. We have compared generated code with optimized BLAS library function. Different algorithms have been generated: row-column multiplication, multiplication by block, multiplication by block using optimized BLAS function for the sequential part. Those algorithms have been compared with the sequential BLAS function and the parallel BLAS function. The results [80] show that the way to use Gaspard2 in the High Performance Computing field is to entrust Gaspard2 to manage parallelism and to use optimized function for the sequential part.
