[mpich-discuss] no process manager installed?

[Rolf Kuiper]

Hi Rajeev,

thanks for your prompt reply!

Sounds promising, but when I ask for the local rank number via
	MPI_Comm_rank(MPI_COMM_WORLD, &myrank);
all ranks state to be myrank = 0. So I cannot e.g. use 
	if(myrank == 0) ...

Is there a new/updated routine of  MPI_Comm_rank() available or ...?

Thanks for your help,
Rolf
