Okay. Something must have broken between 4.0.x and 4.1.x to give pbs pro ras
priority over alps even for Cray XC systems.

Okay, try setting this environment var
Okay, try setting this environment variable and see if the mpirun command works:
export OMPI_MCA_ras=alps

Hi Chris
I wonder if somethings messed up with the way alps is interpreting node names
on the system.
Could you try doing the following:
1. get a two node allocation on your cluster
2. run aprun -n 2 -N 1 hostname
3. take the hostnames returned then run aprun -n 2 -N 1 -L X,Y hostname
Where X=
Thanks Howard. Here is what I got.
