The Standard Performance Evaluation Corp.'s High-Performance Group (SPEC/HPG) is seeking Message Passing Interface (MPI) applications for a new supercomputing benchmarking suite. Submitters whose applications are chosen will influence future designs of hardware and software using MPI. They will receive a free MPI benchmark license and recognition on the SPEC website and in media materials. The MPI benchmark will provide performance metrics that can be used to compare different hardware architectures (SMP, NUMA, clusters) and interconnects, processors, memory hierarchy, compilers, and MPI implementations. MPI applications from any application area can be submitted, but SPEC prefers programs that are considered state-of-the-art in a given field. The application should also be portable across different hardware and software architectures. An entry form for submissions can be found at: www.spec.org/mpi/submissions.html. Submitters will also need to fill out a permission-to-use form that gives SPEC the right to distribute the program as part of a benchmark suite.
