is there a cluster admin you can ask? I think the ncpus and mpiprocs being 1 is the answer. Normally we connect to PBS via RSM and RSM knows how to submit the correct PBS command to launch the job. I think it first requests of PBS the compute node list and number of cpu cores on each to use, given the total number of cpu cores you requested to solve on. I think these are stored as variables and used in the select/ncpus/mpiprocs line.
