Hi all again, I have had a simple implementation working. Now I need to look at a situation when -pe is specified. It looks like the accurate way to determine host/slot allocation is to get from $pe_hostfile. But $pe_hostfile seems to be available only in start_proc_args.
Does this mean in -pe situation, the quota should be created in a script that is specified in start_proc_args instead of prolog?
