-Currently, there are 64 standard compute nodes available in the shared partition. These nodes have 250GB of usable RAM and 104 cores. By default, your job will be allocated 1.024GB of RAM per core requested To change this amount, you can use the ```--mem``` or ```--mem-per-cpu``` flag in your job submission.

 In the shared node partition, the value for `Number of Nodes` can be a fraction of a node. This value will be calculated based on either the amount of cores or the amount of memory requested, whichever is a greater percentage of the total of that resource available on the node.
