This paper discusses issues in developing a version of the Level 3 BLAS for distributed memory concurrent computers. The Level 3 BLAS are particularly important when using machines with hierarchical memory as they maximize reuse of data in the upper levels of the memory hierarchy. In implementing the distributed Level 3 BLAS a block scattered decomposition is employed. Details of the parallel implementation of DGEMM, for performing matrix-matrix multiplication, and DTRSM, for solving triangular systems, are given, and results are presented for runs on the Intel Touchstone Delta computer.
