On SMP clusters, mixed mode collective MPI communications, which use shared memory communications within SMP nodes and point-to-point communications between SMP nodes, are more eļ...

As new processor and memory architectures advance, clusters start to be built from larger SMP systems, which makes MPI intra-node communication a critical issue in high performanc...
Many parallel applications from scientiļ¬c computing use MPI global communication operations to collect or distribute data. Since the execution times of these communication opera...
Buffered CoScheduled MPI (BCS-MPI) introduces a new approach to design the communication layer for largescale parallel machines. The emphasis of BCS-MPI is on the global coordinat...
This paper presents Two-Phase Compressed I/O (TPC I/O,) an optimization of the Two-Phase collective I/O technique from ROMIO, the most popular MPI-IO implementation. In order to r...
