The Caldera cluster has been expanded with the addition of 14 non-GPU nodes, giving users additional resources for analysis and visualization.
Caldera initially comprised 16 nodes, each of which has two NVIDIA GPUs. The 14 new nodes were added when CISL repurposed the Pronghorn evaluation cluster.
Except for lacking GPUs, the added nodes are the same as the other Caldera nodes, each with two 8-core, 2.6-GHz Intel Xeon E5-2670 (Sandy Bridge) processors and 62 GB of usable memory. Because they share the same node and processor architecture as Yellowstone, Caldera nodes can also be useful for compiling codes for Yellowstone or testing Yellowstone codes on a smaller scale.
To submit jobs that do not require GPUs, specify the “caldera” queue in your job script. Jobs that need exclusive use of nodes for GPGPU or visualization applications should specify the “gpgpu” queue.
See the Geyser and Caldera documentation for additional information or email firstname.lastname@example.org for assistance in deciding which resource is most appropriate for your work.
