      • These are the release notes for Torque, 2.5.7-1 from EPEL 5 :
Changed:
<
<
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.
        [1] http://code.google.com/p/munge/ 
        [2] https://admin.fedoraproject.org/community/?package=munge#package_maintenance

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 Change Log. The significant changes that require action prior to upgrade are however detailed above

yum-autoupdate settings:

As good practice is suggested to disable the yum-autoupdate service. Any other settings is decided at site-manager own risk!

To disable the service it is available the following script "disable_yum.sh" (thanks Giuseppe Platania) that can be used to REALLY disable yum-autoupdate.
