Prior to joining the staff of CASC in 1997, Van spent seven years on the faculty of the Naval Postgraduate School in Monterey, California. Abstract Abstract Partial Differential Equation simulations based on finite discretizations on static grids scale well in parallel, but execute at a disappointing percentage of per-processor peak floating point operation rates without special attention to layout and access ordering of data. These basic performance characteristics of PDE-based codes can be understood with surprisingly simple models. The performance models and experimental results motivate algorithmic and software practices that lead to improvements in both parallel scalability and per node performance. This snapshot of ongoing work updates our 1999 Bell Prize-winning simulation on DOE's ASCI computers.
