Recently I’m studying some manuals to help the strategy decision of updating our 15 HP machines cluster to a more recent version of the operating system, splitting it in 2 functional branches.

One for GRID like calculation and one for a proprer application cluster.

Since the systems now runs something between Red Hat AS Linux 3.* with many addictional packages from the Scientific Linux repositories I had the chance to express my desire to have a SL driven GRID machine and then an eleven nodes CentOS cluster.

So I saw some interesting news on their front:

• the growth of the CentOS wiki contents and activities;
• a newborn Planet CentOS aggregator of the blogs present in the CentOS community;
• the spreading of the new 5.1 release, just after the Prominent North American Vendor! Here the release notes.
