“This is an exciting time because the whole HPC landscape is changing with manycore, which is a big change for our users,” said Gerber, who joined NERSC’s User Services Group in 1996 as a postdoc, having earned his PhD in physics from the University of Illinois. “Users are facing a big challenge; they have to be able to exploit the architectural features on Cori (NERSC’s newest supercomputing system), and the HPC Department plays a critical role in helping them do this.”
