Abstract:This report illustrates the annual progress of the program “parallel adaptive structured mesh applications infrastructure” in 2011. Driven by the function demand from the complexity and diversity of real application and the performance demand of transition from hundreds to thousands cores to thousands to tens of thousands cores, within the framework of research on the JASMIN infrastructure, the program made deep investigations mainly on data structure, communication algorithm for irregular data, load balance algorithms, parallel adaptive grid method, parallel algebraic multi-grid algorithms, high performance parallel algorithms and advanced numerical methods, etc. Some breakthroughs have been made about critical algorithms and key technologies. The research achievements have been integrated into JASMIN infrastructure, based on which the performance of JASMIN and many application codes have been improved dramatically, and many application codes have got the ability to simulate on tens of thousands of cores. In general, the annual goals of the program have been fulfilled successfully.
Key Words:JASMIN infrastructure;Parallel algorithm;Ddata structure;Load balance algorithm;Fast algorithm;Advanced numerical method
