The Computer Resource Team (CRT) is the component of the PSAAP IV program that connects center researchers with the High Performance Computing (HPC) resources required to perform their work.
The CRT is comprised of representatives from each NNSA Lab who are familiar with their Lab's computing resources, personnel and policies. The following individuals serve on the CRT:
- Tim Fahey, LLNL (chair); fahey2 [at] llnl.gov (fahey2[at]llnl[dot]gov)
- Andres De La Cruz, LLNL; delacruz10 [at] llnl.gov (delacruz10[at]llnl[dot]gov)
- Giovanni Cone, LANL; conega [at] lanl.gov (conega[at]lanl[dot]gov)
- Amanda Sena, SNL; alsena1 [at] sandia.gov (alsena1[at]sandia[dot]gov)

The primary computing systems available to PSAAP IV Centers are shown in the table below. Other computing platforms at LANL, LLNL, and SNL may be available to provide access to a greater variety of architectures and software stacks; interested Centers should reach out to the CRT, AST, and/or TST for more information.
