The SKaMPI-Benchmark is a suite of tests designed to measure the performance of MPI. MPI (Message Passing Interface) is a machine independent standard to provide an efficient interface to message passing libraries of different parallel machines. The goal of SKaMPI is to create a database to illustrate the performance of these different MPI implementations. This database should allow to: 1. Decide how to implement portable and efficient MPI programs. 2. Predict the performance of MPI programs. 3. Describe supercomputers in terms of MPI.
