Dear William,
yes, it is tightly integrated and this was working fine before the upgrade
and is still working fine with openmpi. The pstree output looks like this
on a slave node:
|-sge_execd-+-load-sensor
| |-sge_shepherd-+-mycoshepherd
| |
|-qrsh_starter---hydra_pmi_proxy---8*[mpitests-IMB-MP---{mpitests-IMB-M}]
| | `-6*[{sge_shepherd}]
| `-4*[{sge_execd}]
So the MPI processes are all children of the execd.
