Abstract
Two driving forces behind high-performance clusters are the availability of modern
interconnects and the advent of multi-core systems. As multi-core clusters become
commonplace, where each core will run at least one process with multiple intra-node and
inter-node connections to several other processes, there will be immense pressure on the
interconnection network and its communication system software.
Many parallel scientific applications use Message Passing Interface (MPI) collective
communications intensively. Therefore, efficient and scalable implementation of MPI
