-====== GPU Queues ====== 
  
-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. 
- 
-====== GPU Usage ====== 
- 
-To use a GPU you have to explicitly reserve it as a resource in the bsub call: 
- 
-<code bash> 
-$ bsub -n 1 -R '​select[cuda=1],​rusage[cuda=1]'​ -q gpulong ./​my_program 
-</​code>​ 
- 
-The code or application to be carried out needs to 
-  - be an executable script or program. 
-  - carry [[http://​en.wikipedia.org/​wiki/​Shebang_%28Unix%29|shebang]]. 
- 
-While this is true for LSF in general, it is imposed for the GPU-resource requests.
