Porting scientific libraries to PGAS in XSEDE resources: practice and experience

摘要: The next generation of supercomputers presents new and complex challenges that might require a change in the current paradigm how parallel applications are developed. Hybrid programming is usually described as best approach for exascale computers. PGAS models considered an interesting alternative to work together with MPI this hybrid model achieve good performance those machines. This very promising especially one-sided irregular communication patterns. However, still emerging technology there not much previous experience on port existing model. Due relevance devices, it relevant have early porting well knowledge issues be faced paradigm. In paper we present two different scientific currently implemented candidates We describe these been ported, some solutions found. also show can great when compared MPI.
