‘Summit on Summit, Sierra, and Perlmutter’ Hits 2nd Anniversary of Team-Effort Problem-Solving

With every new generation of supercomputer that arrives at the nation’s leadership computing facilities also comes an inevitable learning curve as computational scientists get acclimated to unfamiliar systems. Software bugs must be hunted down and hardware quirks ironed out. But even after those initial issues are resolved, there is an…
