Title:

Scientific Parallel Computing on NWICG/OSG

Abstract:

Parallel computing through the grid middleware on the OSG stack is one of ongoing challenges in NWICG. In this presentation, I will introduce experiences for the parallel computing on NWICG (between Notre Dame and Purdue). In particular, issues on integration between MPICH and SGE on the OSG stack will be discussed. Moreover, NERSC is a site which supports SGE and parallel computing environments to OSG users. Through this presentation, I hope that NERSC and NWICG could exchange information and experience and could be discussed on developing and providing optimal environments for parallel computing on OSG. The second author currently performs numerical weather simulations using the Weather Research and Forecast (WRF) model v2.2 from the National Center for Atmospheric Research (NCAR) and will soon upgrade to the newly released v3.0 of the model. This research is in collaboration with the T.N. Krishnamurti group at Florida State University performing mesoscale simulations of tropical cyclones. A new line of research is also emerging with Purdue University in the area of resolving convective scale weather systems under future climate change scenarios. Each of these endeavors involves collaboration with external institutions. At NWICG_NotreDame we seek to develop grid middleware to facilitate the use of computer resources by all team members and then to share this middleware through organizations such as the Engage VO at the Renaissance Computing Institute (RENCI) in North Carolina.
