It fails because Intel mpi is calling pbsdsh with -h and that is not a valid flag for pbsdsh.
There also should be a -- before calling hydra_bstrap_proxy.
Usage: /opt/pbs/bin/pbsdsh [-c copies][-s][-v][-o] -- program [args...]
/opt/pbs/bin/pbsdsh [-n node_index][-s][-v][-o] -- program [args...]
/opt/pbs/bin/pbsdsh --version
Where -c copies = run a copy of "program" on the first "copies" nodes,
-n node_index = run a copy of "program" on the "node_index"-th node,
-s = forces synchronous execution,
-v = forces verbose output.
-o = no obits are waited for.
We are forced to do
export I_MPI_HYDRA_BOOTSTRAP=ssh
Wondering what version of pbsdsh Intel MPI is tested against and if it could be made to do the right thing for PBS Pro.
