Comment (by jtao):
I didn't know that a ticket had been created already. :) Ian encouraged me to post to the list and create a ticket.
Just for references:
{{{ // return a unique id for the local host; int CCTK_MyHost(cGH *cctkGH);
// return total number of nodes; int CCTK_nHosts(cGH *cctkGH);
// return number of mpi processes on a given host int CCTK_nProcsOnHost(const int host);
// return a list of process on a given host void CCTK_ProcsOnHost(const int host, int *procs);
}}}
