I again Ralf,

>I gather you have access to bjs? Could you use bjs to get a node allocation,

I have slightly changed my cluster configuration for something like:
master is running on a machine call: machine10
node 0 is running on a machine call: machine10 (same as master then)
node 1 is running on a machine call: machine14

node 0 and 1 are up

My bjs configration allocates node 0 and 1 to the default pool
<--------------->
pool default
      policy simple
      nodes 0-1
<----------------->

Be default, when I run "env" in a terminal, NODES variable is not present.
If I run env under a job submission command like "bjsub -i env", then I can see the following new environments variable.
NODES=0
JOBID=27 (for instance)
BPROC_RANK=0000000
BPROC_PROGNAME=/usr/bin/env

When the command is over, NODES is unset again.

What is strange is that I would have expected that NODES=0,1. I do not know if you bjs users have the same behaviour.

Hopefully, it is the kind of information you were expecting.

Regards.

Herve
