+This is expected. The maximum speed this server will ever be able to achieve is 1Gb/s because of its single 1G ethernet uplink. If this cluster gains in popularity we plan on upgrading the network and storage server.

 | **debug** | The partition your job will be submitted to if none is specified. The purpose of this partition is to make sure your code is running as it should before submitting a long running job to the general queue. |
 | **general** | All jobs that have been thoroughly tested can be submitted here. This partition will have access to more nodes and will process most of the jobs. If you need to use the ''%%--exclusive%%'' flag it should be done here.|
+| **gpu** | Contains servers with graphics cards. As of 20160506 there is only one node containing a Tesla M2090. You will be forced to use this server exclusively for now. |

 will start a command line shell (''%%/bin/bash%%'') on the 'general' queue with 500 MB of RAM for 6 hours; 1 core on 1 node is assumed as these parameters (''%%-n 1 -N 1%%'') were left out. When the interactive session starts, you will notice that you are no longer on a login node, but rather one of the compute nodes dedicated to this queue. The ''%%--pty%%'' option allows the session to act like a standard terminal.
