The Scientific Computing Group (SCG) works concurrently with the users of HPC systems to help them obtain optimal results from the OLCF’s computational resources. The SCG is comprised of research scientists, visualization specialists, and work-flow experts who are trained in chemistry, physics, astrophysics, mathematics, numerical analysis, or computer science. Each research team using an OLCF system is assigned an SCG liaison who is familiar with the field of research. SCG liaisons actively participate in the research, help design and optimize code for the users’ applications, streamline the work flow, and solve any computer issues that arise. Visualization specialists capture the resulting data in images and help the users analyze it.
