 ====GPU compute servers====
-We have 2 Linux GPU compute servers available in COM for staff use.
+We have a Linux GPU compute server (hostname **''ford.dcs.shef.ac.uk''**) available in COM for staff use.
-''ford'' and ''arthur'' have NVIDIA GeForce RTX 3060 cards.
+It is **experimental** system built mostly from spare parts and should not be expected to provide rock-solid service, so it is suggested it mainly be used for testing/developement.
-The OS is Ubuntu Server, and the CUDA libraries are available in /usr/local/cuda. You can see the current usage status of the GPUs and which version of the NVIDIA CUDA drivers are available by running the **gpustat** command.
-You can access the server remotely from on-campus or from VPN, via SSH with your ITS username/password.

-**Requesting access to these servers**
+**Requesting access**\\
+Any staff/PhD in COM can have access but they must first request it using the COM SR system so they can be added to the access list on the server. See [[Contacting Technical Support]] for how to.

 **Resource sharing / Job submission**\\
-No job submission system is //currently// installed on the system. If we do find that usage is high then we might have to re-consider this in future. For the moment, users should be aware that others may be using the system at the same time and therefore should not necessarily expect 100% access to the processing capability.

 **Support for GPU computing**\\
-COM Tech Support cannot provide help for programming the GPU cards. The system is provided for those who already know how to use the GPU capability, or can find out how to do it.

 **Data storage**\\
-There is some Terabytes of storage in /data available on both servers, which should be considered a temporary working area or scratch space.\\
+There is some 10 Terabytes of storage in /data available which should be considered a temporary working area or scratch space. //When it fills up, the oldest data will be deleted to make more room//.\\
-Your U-drive is mounted under $HOME and this should be the place to store anything you want to keep permanently. The quota for that is normally 10GB but you can request more from ITS Helpdesk if required.\\
+This in addition to the home directory (20GB quota) at $HOME, which is backed up weekly.\\
-The $HOME (~) area is only for storage of dotfiles etc. and only has a small quota (1GB).
