## Compute Nodes

Oscar has compute nodes in the partitions listed below.

* **batch** - The batch partition is for programs/jobs which need neither GPUs nor large memory.
* **bigmem** - The bigmem partition is for programs/jobs which require large memory. 
* **debug** - The debug partition is for users to debug programs/jobs.
* **gpu** - The gpu partition is for programs/jobs which require GPUs.
* **gpu-debug** - The gpu-debug partition is for users to debug gpu programs/jobs. 
* **gpu-he** -The gpu-he partition is for programs/jobs which need to access high-end GPUs. 
* **vnc** - The vnc partition is for users to run programs/jobs in an graphical desktop environment. 

Below are node details including cores and memory for all partitions.
