cluster:Torque/216/server/install/notes
The D-Grid reference installation has the Torque batch system for jobs management. To install the Torque batch system:
- Torque server installation (on which the pbs_server and maui scheduler are running)
- Torque clients installation (gLite-CE, Globus GRAM und UNICORE NJS) which sent a Batch-jobs
- Worker Nodes (cluster, on which the pbs_mom daemon is running)
WARNING: The three middleware frontends for Job Submission (gLite-CE, Globus GRAM and Unicore NJS) must be configured as torque clients with MAUI. The following packages are required in each of the three front ends (unless specifically stated, the steps as root):
- torque
- torque-client
- maui
- maui-client
Unless specifically stated, the installation and configuration steps as root user.
Selecting the cluster scheduler is an important decision and significantly affects cluster utilization, responsiveness, availability, and intelligence. The default TORQUE scheduler, pbs_sched, is very basic and will provide poor utilization of your cluster’s resources. Other options, such as Maui Scheduler is highly recommended. If using pbs_sched, start this daemon now. If using Maui, refer to the next installation steps.
