Simulation of scientific programs on parallel architectures
In this paper a method is presented to model and simulate scientific application that are implemented as SPMD programs with message-passing. This method is based on the counting of basic operations and the recognition of known kernels. A Fortran analyzer was built to generate automatically a model of such an application for the simulation tool of the MIMESIS project, developed at EDF (Electricité de France). Models of distributed-memory computers, employing this model description, were implemented within the prototype of the project. The approach was validated with two EDF codes, for which the simulations gave good results.
