Install Torque/PBS

Torque on GridVM

A "neutral" version of Torque from ATRPMS:

yum --enablerepo atrpms install torque-server torque torque-scheduler torque-mom

is too old!

Use instead glite-lcg_ce_torque.repo, disabling the CE repo, leave only torque parts

# yum install torque-server-2.1.9 torque-client-2.1.9
# yum install maui-server-3.2.6p19_20.snap.1182974819-4.slc4 maui-client-3.2.6p19_20.snap.1182974819-4.slc4

Some packages to configure pbs the way gLite likes

Maybe OSG will like it too, or at least I'll learn something.

# yum install edg-pbs-utils lcg-pbs-utils lcg-info-dynamic-pbs \
glite-yaim-torque-server glite-yaim-torque-utils
