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:- 30 GPU nodes - each containing two CPUs with 20 cores each for a total of 40 cores, 384GB RAM, and each including one V100 Nvidia GPU accelerator
- 5 GPU nodes - each containing two CPUs with 20 cores each for a total of 40 cores, 384GB RAM, and each including two V100 Nvidia GPU accelerators
- *Coming Soon -* 2 GPU nodes – each containing 4 V100 GPUs and two CPUs that are Intel Xeon Gold 6248, 20C each (coming soon)
- Two large-memory nodes, each containing four CPUs with 20 cores each for a total of 80 cores, and each including 1.5TB of RAM
- Total TFlops across CPUs and GPUs: 387
- 6032 total CPU cores on compute and GPU nodes
- 100Gb/s Infiniband storage network connectivity
- DDN fault-tolerant storage array with 1PB of shared storage utilizing the Lustre file system
- A cumulative total of 250TB of local scratch space spread evenly among each physical compute node
