In this paper we present our work on the the parallelization of a matrix multiplication code based on the hypermatrix data structure. We have used OpenMP for the parallelization. We have added OpenMP directives to a few loops and experimented with several features available with OpenMP in the Intel Fortran Compiler: scheduling algorithms, chunk sizes and nested parallelism. We found that the load imbalance introduced by the hypermatrix structure could not be solved by any of those OpenMP features.
