gpushort/long
queues on these nodes - access however is restricted.This is an old revision of the document!
There are three different Queues inside the cluster that support gpu usage: The titan-Queues (titanshort/long
) currently include hosts i0001-i0009, while the gpu-Queues (infogpu
) include the hosts g0001-g0009 1). 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.
To use a GPU you have to explicitly reserve it as a resource in the submission script:
#!/bin/bash # ... other SBATCH statements #SBATCH --gres=gpu:<number> #SBATCH -p <appropriate partition>
Number can be anything from 1-4 on our GPU nodes. In order to use more than 1 GPU the application needs to support using this much, of course.
In order to use multiples nodes, you have to request more than one node.
