SCARF has a two small groups of GPU equipped nodes, 12 nodes containing dual K40 cards and 12 nodes containing dual K80 cards. The K40 hosts are for a particular project and are submitted to using the restricted queues fbioctopus and fbioctopus-exclusive. The K80 nodes are available for general use and can be submitted to using the emerald-k80 and emerald-k80-exclusive queues. Please contact us if you wish to submit to those queues. For historical reasons, they have a slightly different software payload to SCARF hosts.
