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.
