=== Description of the hardware ===
* One node with 2 NVidia Tesla M2050 (2.6GB) GPU cards, 8 cores, 12GB of ram and 160 GB of /scratch <br>
* Two nodes with each 6 NVidia Tesla M2075 (5.3GB) GPU cards, 24 cores, 64 GB of ram and 820 GB of /scratch<br>
<br>

=== Queues ===
We have 3 queues:
* '''gpu2''': has the 1 node with the 2 GPUs
* '''gpu6''': has the 2 nodes with the 6 GPUs each, so 12 GPUs in total
* '''gpu''': has all 3 nodes


=== Running Jobs using the GPUs ===
[[File:Exclamation-mark.jpg|left|25px|line=1|]] As we are no experts and don't use the GPUs ourselves, this is really work-in-progress. Please share with us and update this page if you have more in-depth information !

Inside your jobs, you need to export the number of available GPUs to your environment.
A small script has been written to do so, so just add it in your qsub scrip:
 . /swmgrs/icecubes/set_gpus.sh
This should give you something like:
<pre>env|grep CUDA
CUDA_VISIBLE_DEVICES=0,1,2,3,4,5</pre>

Then just send as usual your job using one of the GPU queues:
 qsub -q gpu myscript.sh
