-==== Computing Resources ==== 
-The CS Dept. deploys general purpose compute and GPU compute servers, as well as specialized GPU servers. We also have database, [[nx_lab|NX/​Nomachine (graphical desktop)]], and [[windows_server|Windows servers]]. This section describes the general use and research use servers (see other sections for database and other server information). 
- 
-=== //portal// load balanced servers === 
-The //portal// servers are general purpose servers into which anyone can login. They are available for general use. They are also the "jump off" point for off Grounds connections to the CS network. The servers are in a load balanced cluster, and are accessed through //ssh// to ''​%%portal.cs.virginia.edu%%''​. See: [[compute_portal|The portal cluster]] 
- 
-Use these servers to code, compile, test, etc.. However these are //not// meant for long running processes that will tie up resources. ​ Computationally expensive processes should be run on other servers listed below. ​ 
- 
-**All GPU, Memory, CPU, etc. counts are per node**.

- 
-=== GPU servers === 
-The gpusrv* servers are general purpose servers that contain GPUs into which anyone can login (via '​ssh'​). They are intended for code development,​ testing, and short computations. Long running computations are discouraged,​ and are better suited to one of the GPU servers controlled by the job scheduler (see the next section). ​

- 
-=== Nodes controlled by the SLURM Job Scheduler === 
- 
-//See our main article on [[compute_slurm|Slurm]] for more information.//​ 
- 
-These servers are available by submitting a job through the SLURM job scheduler. ​ 
- 
-Per CS Dept. policy, servers are placed into the SLURM job scheduling queues and are available for general use. Also, per that policy, if a user in a research group that originally purchased the hardware requires exclusive use of that hardware, they can be given a reservation for that exclusive use for a specified time. Otherwise, the systems are open for use by anyone with a CS account. This policy was approved by the CS Dept. Computing Committee comprised of CS Faculty. 
- 
-This policy allows servers to be used when the project group is not using them. So instead of sitting idle and consuming power and cooling, other Dept. users can benefit from the use of these systems.

- 
-=== Group specific computing resources === 
-Several groups in CS deploy servers that are used exclusively by that group. Approximately 40 servers are deployed in this fashion, ranging from traditional CPU servers to specialized servers containing GPU accelerators.
