About Arc Cluster
Arc is UTSA's primary high-performance (HPC) resource; utilized by researchers, students, faculty and staff from a broad range of disciplines. Currently, Arc is compromised of 156 nodes totalling 14,864 cores and features:- 172 total compute/GPU nodes and 2 login nodes, majority of these are Intel Cascade Lake CPUs and some are AMD EPYC CPUs
- 22 GPU nodes - each containing two Intel CPUs with 20-cores each for a total of 40 cores, one V100 Nvidia GPU accelerator and 384GB of RAM
- 9 GPU nodes - each containing two Intel CPUs with 20-cores each for a total of 40 cores, two V100 Nvidia GPU accelerators and 384GB of RAM
- 3 NVIDIA DGX nodes - each having two AMD EPYC CPUs with 64-cores each for a total of 128 cores, eight Nvidia A100 80GB GPUs and 2TB of RAM
