mpirun.hydra with -rmk pbs switch and Torque

Hi,

Could you please explain, what the -rmk option for Hydra launcher does. Intel MPI Documentation says that it is to specify "resource management kernel", with the only option being "pbs".

Would the option make mpiexec.hydra to, say, automatically pick the nodelist from Torque MOM's? And/or, to kickstart processes on the compute nodes using Torque TM API?

Thank you very much!

Hi Grigory,

The -rmk option is used to allow MPI to obtain a hostlist from Torque*/PBS*. Processes are still launched using Hydra. We are currently working to improve integration with these job schedulers.

Dear James,

Thank you for the quick answer!

Then, what about my next question, on how to do mpicleanup?

Hi Grigory,

That question is in another thread, and answered there.
