I tried replacing the call to mpirun with mpiexec.hydra and it seems to work
successfully as before. Please find below the contents of *.sh.o#### file
corresponding to the Hello, World! run spanning more than one compute node:

| These two PEs are created by me (not from Rocks) to help our researchers pick
one depending on the nature of their job. If a software suite required that all
processors/cores belong to the same physical compute node (e.g., MATLAB with
Parallel Computing Toolbox), then they would use mpich_staged. If a software
suite could spread the job amongst processors from multiple compute nodes
(e.g., Hello World, VASP, LAMMPS, etc.), then they would use mpich_unstaged.

I do not need mpdboot. The PE used for this purpose is called mpich_unstaged
(basically, a copy of the original mpich with '$fill_up' rule). The only other
PE in this system is called mpich_staged (a copy of the original mpich with
'$pe_slots' rule).
| |
| | I have no clue what mpich_(un)staged refers to, I assume it's some setting
from ROCKS. Can you please post the particular PE settings you want to use
during submission.

I ensured the extend-*.xml files had no error in them using the xmllint command
before rebuilding the distribution. All six compute nodes installed
successfully, and so did running several test "Hello, World!" cases up to 72
cores. I can SSH into any one of these nodes, and SSH between any two compute
nodes just fine.

no call to `qrsh` automatically set up as you would need to start certain
daemons beforehand.
