I've installed 4 GPU-equipped servers in my environment; 2 are a part of my cluster, and 2 are independent from the cluster so that users can login interactively and program/debug/tinker/whatever. (My cluster doesn't allow interactive logins by design). A handful of users were interested in getting access to the GPUs, but so far, not a single one has even logged into these systems to kick the tires yet, and the systems have been online for approx. 9 months. It just be that they're busy with other work. Most of my users are post-docs who guide their own research, so they can create/modify their own project schedules as they see fit. -- Prentice _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
