Hi,

I would like to run both pvm and mpi programs together.
The architecture of the application is the following:
A Pvm program, called master_pvm, spwans P tasks, named
salve_mpi. Each of these tasks, is both a pvm task and a
mpi task.
There are two problems:
1/ The call to the MPI_Init routine produces an error, it seems
that you cannot spawn a mpi process without the mpirun command ?
Is it true ?
How can I avoid this problem ?
2/ If I succeed in solving the previous problem, how can I tell
to all my mpi processes that they belong to a sme group of communication ?
May I use inter-communicators ?

PS: I use PVM version 3.3.10 and MPICH on a network of HP stations.

Thanks for any help.
