lux System Configuration

Compute System Overview

The lux system is based on 3 login servers (lux-0, lux-1, and lux-2) and 108 Dell compute nodes. The compute nodes each have 2x 20-core Intel Xeon Gold 6248 (Cascade Lake) CPUs, 192GB RAM, 2.4TB SSD local scratch space, and 100 GB/s Mellanox HDR non-blocking Infiniband networking. There are 80 CPU-only nodes (node001-node080) and 28 GPU-enabled nodes (gpu001-gpu028) that have 2x NVIDIA 32GB V100 GPUs.

Instructions for getting access and using the system are available on the Getting Started and Using *lux* pages.

Facilities Statement for Grants

You may wish to include a description of lux in your facilities / equipment statement for grant or national supercomputing applications:

UC Santa Cruz hosts a new high-performance computer lux funded by NSF MRI grant AST 1828315, installed at the UCSC Data Center. This new Dell system features 108 nodes, each with 2x 20-core Intel Xeon Gold 6248 (Cascade Lake) CPUs, 192GB RAM, 2.4TB SSD local scratch space, and 100 GB/s Mellanox HDR non-blocking Infiniband networking. Of the compute nodes, 28 include 2x NVIDIA V100 32GB GPUs (56 total). The lux system also features a 3.6PB DataDirect Networks Lustre storage system Infiniband-connected directly to the compute nodes, allowing for high throughput attached storage.
