NAME

environment - rheolef initialization (rheolef-6.7)

SYNOPSYS

This class is mainly used to initialize the MPI library: it should be called juste after the main(argc,argv) declaration as in: #include "rheolef.h" using namespace rheolef; int main(int argc, char**argv) { environment rheolef (argc, argv); ... } An optional third argument of the environment constructor allows to set the MPI thread feature. By default, its value is MPI_THREAD_SINGLE, as defined in mpi.h. Other possible values are related to MPI multi-threaded, see the MPI documentation for more details.
