Subject: [OMPI users] Option -cpus-per-proc 2 not working with given machinefile?
From: Reuti (reuti_at_[hidden])

Hi,

I have an issue using the option -cpus-per-proc 2. As I have Bulldozer machines and I want only one process per FP core, I thought using -cpus-per-proc 2 would be the way to go. Initially I had this issue inside GridEngine but then tried it outside any queuingsystem and face exactly the same behavior.

@) Each machine has 4 CPUs with each having 16 integer cores, hence 64 integer cores per machine in total. Used Open MPI is 1.6.4.

a) mpiexec -cpus-per-proc 2 -report-bindings -hostfile machines -np 64 ./mpihello

and a hostfile containing only the two lines listing the machines:

node006
node007

This works as I would like it (see working.txt) when initiated on node006.

b) mpiexec -cpus-per-proc 2 -report-bindings -hostfile machines -np 64 ./mpihello

But changing the hostefile so that it is having a slot count which might mimic the behavior in case of a parsed machinefile out of any queuing system:

node006 slots=64
node007 slots=64

This fails with:

--------------------------------------------------------------------------
An invalid physical processor ID was returned when attempting to bind
an MPI process to a unique processor on node:

 Node: node006

This usually means that you requested binding to more processors than
exist (e.g., trying to bind N MPI processes to M processors, where N >
M), or that the node has an unexpectedly different topology.

Double check that you have enough unique processors for all the
MPI processes that you are launching on this host, and that all nodes
have identical topologies.

You job will now abort.
--------------------------------------------------------------------------

(see failed.txt)

b1) mpiexec -cpus-per-proc 2 -report-bindings -hostfile machines -np 32 ./mpihello

This works and the found universe is 128 as expected (see only32.txt).

c) Maybe the used machinefile is not parsed in the correct way, so I checked:

c1) mpiexec -hostfile machines -np 64 ./mpihello => works

c2) mpiexec -hostfile machines -np 128 ./mpihello => works

c3) mpiexec -hostfile machines -np 129 ./mpihello => fails as expected

So, it got the slot counts in the correct way.

What do I miss?
