-====== GPU Queues ====== 
  
-There are three different [[queues|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 ((formally there have been the ''​gpushort/​long''​ queues on these nodes - access however is restricted.)). 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. 
- 
-====== GPU Usage ====== 
- 
-To use a GPU you have to explicitly reserve it as a resource in the submission script: 
- 
-<code bash> 
-#!/bin/bash 
-# ... other SBATCH statements 
-#SBATCH --gres=gpu:<​number>​ 
-#SBATCH -p <​appropriate partition>​ 
-</​code>​ 
- 
-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. 
- 
-===== Using multiple nodes and multiple GPUs ===== 
- 
-In order to use multiples nodes, you have to request more than one node.
