>From what I could see in the HOD code, it appears you cannot override the ppn value with HOD. You could look at src/contrib/hod/hodlib/NodePools/torque.py, and specifically the method process_qsub_attributes. In this method, the nodes parameter is getting set to the value defined by the -n parameter passed to HOD. Unless I am missing something, this seems to be the final value that can be specified for the nodes parameter to the qsub command. The method I suggested seems like a workaround to circumvent this limitation. In the MAUI documentation, I found it is possible to set the specific parameter per Torque job as well. And there is an option in HOD to specify such additional parameters, using the key resource_manager.attrs. I know this is not an ideal answer for you. But ATM this is all I can think of.
