Years of scientific domain knowledge and code development have been invested in scientific applications which are now considerably more sophisticated than they were when the community adapted to the transition from vector to parallel supercomputing two decades ago. In terms of sheer size, some of the community codes are an order of magnitude larger than they were in the early 1990s.
Also, many of the significant architectural changes expected in the exascale era will be manifest in the next generations of computers, such as the Cori system at NERSC and in the future systems at other DOE national labs.
To help move the DOE research community along the path to exascale computing, Berkeley Lab has led and/or participated in projects that will help both supercomputing centers and users make the transition to next generation systems.
