ISC announces program chair John Shalf 

ISC has announced John Shalf as the ISC 2023 Program Chair. Shalf is Department Head for Computer Science at Lawrence Berkeley National Laboratory (LBNL). He has been working in the field of high performance computing for nearly 30 years – having started at the National Center for Supercomputing Applications (NCSA) in 1994.

The ISC 2023 Conference and Exhibition is the 38th in the series and will be held next year from May 21-25 in Hamburg, Germany. It will be an on-site event and offers comprehensive on-demand content for those unable to attend in person. Over 3,000 attendees are expected to participate in Hamburg.

Shalf is a respected technologist in the high-performance computing (HPC) community and a long-time ISC collaborator. He has delivered invited talks and chaired panels at ISC for over a decade, advocating for a systems architecture to expedite the industry's exascale goals. He has also served on different ISC conference steering committees, helping to shape the technical program.

Behind the scenes, Shalf has lent his expertise to lay the groundwork for executing the US government’s exascale ambition since 2009. He also formerly served as the Deputy Director for Hardware Technology on the US Department of Energy (DOE)-led Exascale Computing Project (ECP) before he returned to his department head position at LBNL. He has co-authored over 100 peer-reviewed publications in the field of parallel computing software and HPC technology.

On his appointment and vision for the conference, Shalf said, “At ISC 2022, we finally saw first light on the new era of exascale computing with the ORNL Frontier system and the EU Lumi following closely in their footsteps. But with the gradual slowing of Moore’s Law, it is time for a new beginning for HPC. Full Release...
