SKaMPI: the special Karlsruher MPI-benchmark. User manual

Reussner, Ralf


SKaMPI is the Special Karlsruher MPI-Benchmark. SKaMPI measures
the performance of MPI implementations, and of course of the
underlying hardware. It performs various measurements of several
MPI functions. SKaMPI's primary goal is giving support to
software developers. The knowledge of MPI function's
performance has several benefits: The software developer knows
the right way of implementing a program for a given machine,
without (or with shortening) the tedious time costly tuning,
which usually has to take place. The developer has not to wait
until the code is written, performance issues can also
be considered during the design stage. Developing for
performance even can take place, also if the considered target
machine is not accessible.

MPI performance knowledge is especially important, when
developing portable parallel programs. So the code can be
developed for all considered target platforms in an optimal
manner. So we achieve performance portability, which means that
code runs without time consuming tuning after recompilation on a
new platform.
