Welcome To RCSG!


The Research Computing Support Group at UTSA provides computing, storage and visualization resources to support research that has specialized or highly intensive computation, storage, bandwidth or graphics requirements. Typical applications include statistics, data analysis, molecular modeling, scientific and engineering simulation and visualization.

Research Computing resources and services are widely used by faculty and student researchers alike. Please contact us for any additional information at RCSG@utsa.edu. For technical support, please submit a support request by clicking this link to ServiceNow. (instructions for submitting support requests can be found here.) For after hours emergency support, please contact University Technology Solutions (UTS) at 210-458-5555.

 

Arc is UTSA's free HPC resource for faculty and students. Arc comprises:
  • 156 total compute/GPU nodes (6032 total cores across all nodes) and 2 login nodes, majority of these are Intel Cascade Lake CPUs
  • 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
  • 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
  • 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
  • 100Gb/s Infiniband connectivity
  • Two Lustre filesytems: /home and /work, where /home has 110 TBs capacity and /work has 1.1 PB of capacity
  • A cumulative total of 250TB of local scratch (approximately 1.5 TB of /scratch space on most compute and gpu nodes)
