The Research Computing Support Group (RCSG) provides general consulting on the resources it manages. 

RCSG can assist with:

  • Guidance on the adoption of HPC in your research and education
  • Advice on software development and application optimization
  • Collaboration on grant development

Although RCSG provides guidance to users, we are unable to perform the actual development, optimization, and data analysis.

Please contact us through the ServiceNow portal to set up a meeting with the experienced RCSG staff.
