I'm particularly interested in whether mpiexec recognizes pbs as a possible launcher or not. If it recognizes pbs as a launcher, it should automatically select it where possible.
It is using pbs as the launcher. The problem is with the setting of the session id for the forked hydra_pmi_proxy process on mother superior. Since the hydra_pmi_proxy process has the session id set to the bash process instead mpi_exec process. As a result of this torque is unable to track the resources consumed by the process. If you look at the openmpi processes their session id is set correctly and torque is able to track the resources consumed.
Ah, OK. Sorry I lost track of the original issue in this email chain.
You are right about this issue. The basic problem is that launching proxies using tm_spawn tends to create a different session ID for them.
Isn't it more an issue of Torque? IMO it should either disallow a local TM invocation and return an error, or do correct accounting of it. -- Reuti
I've created a ticket to track it:
