The Oak Ridge Leadership Computing Facility (OLCF) Virtual Crash Course for HPC

By: Linda Hayden

The Oak Ridge Leadership Computing Facility (OLCF) hosted a virtual crash course for High Performance Computing (HPC) December 13-16, 2022. The course covered the foundational skills needed to learn about HPC (e.g., UNIX, command-line text editors, intro C programming), then introduced key concepts for the parallel programming needed to do HPC. Each topic covered in the course consisted of a lecture followed by a hands-on component. SGX3 Workforce Development supported the participation of four students in the Winter Institute:

  • Shovkat Zeynalli (Mississippi Valley State University) 
  • Kevin Chen (University of Maryland, Baltimore County)
  • Andrianina David Raharijao (CUNY Lehman College)
  • John Michael Cabrera (CUNY Lehman College)  

Two of the participating students shared their thoughts. 

Andrianina David RaharijaoAndrianina David Raharijao said “This winter, through the Oak Ridge National Laboratory’s crash course on HPC, not only did I get to learn more about High Performance Computing, but I did so using one of the top supercomputers in the world, Summit.”



John Michael CabreraJohn Michael Cabrera shared, “HPC is about solving the world's largest engineering and science problems with supercomputers. It means to do this efficiently by working in parallelism. I learned also about what a supercomputer is, such as how they are made of computer servers, networks, and storage servers, that are specially optimized to do operations in parallel.”


Students had access to a Unix environment to support their hand-on exercises. Upon completion of the course, students received a certificate and a stipend.
