In this video from ATPESC 2019, Ken Raffenetti from Argonne presents an overview of HPC interconnects.
The Argonne Training Program on Extreme-Scale Computing (ATPESC) provides intensive, two-week training on the key skills, approaches, and tools to design, implement, and execute computational science and engineering applications on current high-end computing systems and the leadership-class computing systems of the future.
Ken Raffenetti received his B.S. in computer science from the University of Illinois at Urbana-Champaign in 2006. He then joined Argonne as a systems administrator, where he has run the critical computational components in MCS: web services, virtualization of servers, our desktop Linux infrastructure, and our configuration management system.
