Hi,
sorry bring this again ... but i hope use spawn in ompi someday :-D
The execution of spawn in this way works fine:
MPI_Comm_spawn ("./spawn1", MPI_ARGV_NULL, 2, MPI_INFO_NULL, 0,
MPI_COMM_SELF, &intercomm, MPI_ERRCODES_IGNORE);
but if this code go to a for I get a problem :
for (i= 0; i < 2; i++)
{
MPI_Comm_spawn ("./spawn1", MPI_ARGV_NULL, 1,
MPI_INFO_NULL, 0, MPI_COMM_SELF, &intercomm[i], MPI_ERRCODES_IGNORE);
}
and the error is:
spawning ...
child!
child!
