Radon cluster unavailable

August 25 – 26, 2009

The Radon Linux cluster will be unavailable Tuesday and Wednesday, August 25-26, for hardware upgrades and a conversion from Debian Linux to Red Hat Enterprise Linux 5 (RHEL5). Since this upgrade changes the version of Linux used on the cluster, all user programs should be recompiled after the upgrade and any PBS jobs that do not complete prior to the upgrade will be deleted and need to be resubmitted.

Update: The Radon cluster's upgrade to Red Hat Enterprise Linux 5 (RHEL5) has been completed and PBS job scheduling was resumed Wednesday evening, August 26. Although some applications compiled prior to the upgrade may continue to work, Radon users are encouraged to recompile their applications for best results.

Please refer questions about this system maintenance to rcac-help@purdue.edu.
