Focus efforts to transition appropriate applications to parallel systems.

There are many large scale user applications that are not presently operational on a parallel platform, but that would benefit from being converted to use one. Efforts to transition applications to the NERSC MPP and future parallel systems should be focussed on these applications. The DOE High Performance Computing Research Centers have done an excellent job in providing resources to the grand challenge community to build their experience base. NERSC is in a unique position to provide both development and production systems to the majority of the ER scientific computing user community.

The choice of a portable programming model and the optimization of software for a particular parallel platform are often in conflict. There is a need to get applications working quickly on the new resource and a need to be portable since the high performance computing systems available for the next NERSC procurement have yet to be completely designed. To meet these multifaceted requirements, including user training, NERSC must have a highly qualified and diverse parallel computational science and applications group that should build strategic partnerships and collaborations with the core ER physical and computational science research efforts.
