There seem to be 3 main opinions in this area of cluster admin: 1) Install little or nothing on the nodes; reboot all the time 2) Heavy install on the nodes; re-image to ensure consistency 3) Heavy install on the nodes; other mechanism to ensure consistency All of these have their pros and cons. You are correct that (2) needs a fast re-image, since you're going to be doing it fairly frequently. But (3) will only re-image once a year or two. Some people in (2) reboot&reimage any time they change a single rpm. That's a recipe for annoying your users, unless you have the ability to do a rolling-reboot between jobs. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
