The related documentation is on installing PBS Pro packages in which there are three types of nodes:
- pbspro-server
- This should be installed on one node (or two if you employ failover) in your cluster where the server and scheduler will run. Most admins prefer not to run jobs on this node, but it is certainly possible. This RPM also installs everything you would get with the execution and client packages.
- pbspro-execution
- This package should be installed on all nodes where you want your jobs to run. It provides the pbs_mom daemon, but not the server or scheduler. Admins generally restrict login access to these nodes to prevent users from logging in and impacting running jobs. This RPM also includes everything you would get with the client package.
- pbspro-client
- This package should be installed on nodes where users are allowed login access, like their workstations. It does not contain any daemons, but allows users to submit and control their jobs.
Compared to CentOS 7.x Rocks cluster 7.0 Son of Grid Engine sge role PBS is more actively maintained and hence preferred over use of SGE in rocks clusters.
