The titan-Queues (
titanshort/long) currently include hosts i0001-i0009, while the gpu-Queues (
gpushort/long) include the hosts g0001-g0009. The titan-hosts carry 4 GeForce GTX TITAN, hence a usage request up to
cuda=4 can be selected (see below). In contrast the GeForce GTX 480 is installed on the gpu-hosts (for the
gpushort/long queues). Finally, for the tesla-Queues (''teslashort/long) 4 Tesla K20m cards are installed.
The max. runtime is analogous to the other short/long-Queues.
To use a GPU you have to explicitely reserve it as a ressource in the bsub call:
$ bsub -n 1 -R 'select[cuda=1],rusage[cuda=1]' -q gpulong ./my_program
