These stats are necessarily simplified. See notes below.

NOTE Due to the mixed nature of the GPUs in this machine, some of the fields that would normally have single integer inputs are not rendering. Here is additional information:

GPU peak performance (TFLOP/s double precision): MI60 = 7.4

GPU Memory/Node (GB): MI60 = 32GB

Peak TFLOPs (GPUs): MI60 = 2,427TF

Also, local NVRAM storage, mounted on each node as /l/ssd (GB): 1500

Job Limits

Each LC platform is a shared resource. Users are expected to adhere to the following usage policies to ensure that the resources can be effectively and productively used by everyone. You can view the policies on a system itself by running:

news job.lim.MACHINENAME

Web version of Corona Job Limits

Hardware

There are 121 compute nodes, each with 256 GB of memory. All compute nodes have AMD Rome processors with 48 cores/node. Each compute node has 8 AMD MI50 GPUs with 32 GB of memory. The nodes are interconnected via InfiniBand QDR (QLogic).

Scheduling

Corona jobs are scheduled through Flux. Slurm wrappers are also loaded by default.

Jobs are scheduled per node. All nodes are in one queue.

The maximum time limit is 24 hours.
