Thanks Howard. Here is what I got.
batch35:/p/work/borchert> mpirun -n 1 -d ./a.out

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=
It’s the same output and the same result:
batch13:~> aprun -n 2 -N 1 hostname
nid00418
nid00419
batch13:~> aprun -n 2 -N 1 -L nid00418,nid00419 hostname
aprun: -L node_list contains an invalid entry
Usage: aprun [global_options] [command_options] cmd1
...
Thanks,
Chris

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

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.
