The traditional way to do this stuff in MPI is
If rank==0 do_master_stuff
Else do_slave_stuff
Sounds like that pattern should apply to your app.
Pvm has been dead for years.
Sent from my phone. No type good.

What wrong with only allowing the rank 0 to execute the code before and after
the funcCompScalapack function as indicated in the example below:
int main()
{
//Initialize MPI
MPI_Init(NULL,NULL);
MPI_Comm_rank(MPI_COMM_WORLD, &myrank);
if( 0 == rank ) {
//some work that mu
I honestly don't know - you'd have to look at the PVM docs. You also might look
at OpenMP and try doing it with multiple threads instead of processes, though
that limits you to running on a single node.

Thank you for your answer.
So I understand that MPI_Comm_spawn() is my function. But I see in the
documentation that the first argument is char* command, and command is the
name of the program to spawn, but I not want to execute an external
program. Only
should work!

I'm writing an example program using ScaLAPACK. I have written the
ScaLAPACK code in an independent function that must be call
Afraid not. You could start a single process, and then have that process call
