Update Information:

**Warning: Significant change, munge enabled - action required:**

The updated EPEL5 build of torque-2.5.7-1 as compared to previous versions enables munge[1] as an inter node authentication method.

It is highly advisable that prior to upgrading to version 2.5.7-1 of this torque package that munge is installed and enabled. A munge package[2] is of course available within EPEL5.

To enable munge on your torque cluster:

 * Install the munge package on your pbs_server and submission hosts in your cluster.
 * On one host generate a key with */usr/sbin/create-munge-key*
 * Copy the key, /etc/munge/munge.key to your pbs_server and submission hosts on your cluster.
 * Start the munge daemon on these nodes.. **service munge start && chkconfig munge on**

**Warning: New internal format for Job arrays:**

TORQUE 2.5 uses a new format for job arrays. It is not backwards
compatible with job arrays from version 2.3 or 2.4. Therefore, it is imperative that the system be drained of any job arrays BEFORE upgrading. Upgrading with job arrays queued or running may cause data loss, crashes, etc, and is not supported.

This update  from 2.3.10 includes numerous bugfixes and enhancements. Please read the torque ChangeLog.The significant changes that require action prior to upgrade are however detailed above.
