The advanced MPI parallel software systems become more complex; a growing number of cores and thus MPI-operations are applied. Moreover, the complexity and ambiguity of MPI standard impose a number of constraints on application of MPI-functions. It complicates the process of writing the correct and machine independent MPI-programs even for experts.
The MCCT tool developed is meant to simplify the search of real and potential problems in MPI parallel code. The given software consistency check component for MPI application is a part of the S-MPI system developed which is the first corresponding commercial product in Russia. A number of examples of the MPI source problem code show an effective problem detection using MCCT. The consistency check results are given for two software packages developed in RFNC-VNIIEF, i.e. LEGAK-DK and LOGOS.
MCCT performance measurements verify its competitive ability.Keywords: MCCT, consistency check, MPI, S-MPI software system.
