Simulation of scientific programs on parallel architectures with MIMESIS environment

The paper presents how a scientific application written using an SPMD programming model with message passing can be modeled and simulated. This description is based on the counting of basic operations and the recognition of known kernels. A Fortran analyzer was built to automatically generate a model of such an application for the simulation tool of the MIMESIS project, developed at EDF (Electricite de France). Models of distributed memory computers, taking advantage of this description, were implemented with the prototype of the project. The approach was validated with two EDF codes, for which the simulations gave good results.
