The Traverse cluster is composed of 46 IBM POWER9 nodes with four NVIDIA V100 GPUs per node. The cluster is primarily intended to support research at the Princeton Plasma Physics Lab (PPPL). Traverse is also available to Princeton researchers whose work is particularly suited to the architecture of this system either because it is very similar to the Summit cluster at Oak Ridge National Laboratory or because the application to be run can take particular advantage of the NVLink architecture. Programs that move a lot of data in or out of the GPU should see an especially large speed up.
System Configuration and Usage
The system head node, traverse, should be used for interactive work only, such as compiling programs and submitting jobs as described below. No jobs should be run on the head node other than brief tests that last no more than a few minutes. Where practical, we ask that you entirely fill the nodes so that CPU core fragmentation is minimized.
Please remember that these are shared resources for all users.
All jobs must be run through the Slurm scheduler.
Traverse will be down for maintenance the second Tuesday of the month from 6 AM - 2 PM.
