Explicitly Assigning Slices to Separate Nodes

Directive:

#PBS -W x=nmatchpolicy:EXACTNODE

Example:

#!/bin/bash
#PBS -l nodes=4:ppn=2
#PBS -W x=nmatchpolicy:EXACTNODE

echo "Script begins here"

Command Line:

qsub -l <resource_request> -W x=nmatchpolicy:exactnode script

Example:

qsub -l nodes=4:ppn=2 -W x=nmatchpolicy:exactnode blast.sh
