MPI_Intercomm_Merge( intercomm, high, newintracomm, ier )
None of the books I have state the variable type of the second
argument for MPI_Intercomm_Merge for Fortran. Class notes I have
from David Cronk state it is a Logical.
In C it is an "int" with values of true and false.
Looking at O
OMPI will use as many slots as Torque tells it to. So if you qsub with
ppn=2, then OMPI will use 2 slots per node; if you qsub with ppn=1, then
OMPI will use 1 slot per node, etc.
OMPI defaults to -byslot scheduling, so if you qsub with ppn=2/OMPI uses
2 slots per node, OMPI will schedule MPI_COM

that will show me this?
The default number of slots will be the number of "cpus" assigned by
