In this paper we describe the difficulties inherent in making accurate, reproducible measurements of message-passing performance. We describe some of the mistakes often made in att...
The Message Passing Interface (MPI) is a standard in parallel computing, and can also be used as a highperformance programming model for Grid application development. How to execu...
The MPI remote-memory access (RMA) operations provide a different programming model from the regular MPI-1 point-to-point operations. This model is particularly appropriate for ca...
Porting on grids complex MPI applications involving collective communications requires significant program modification, usually dedicated to a single grid structure. The diffi...
Abstract. Manually tuning MPI runtime parameters is a practice commonly employed to optimise MPI application performance on a specific architecture. However, the best setting for ...
