MPI/MBCF is a high-performance MPI library targeting a cluster of
workstations connected by a commodity network.
It is implemented with the Memory-Based Communication Facilities
(MBCF), which provides software mechanisms for users to access remote
task's memory space with off-the-shelf network hardware.
MPI/MBCF uses Memory-Based FIFO for message buffering and
Remote Write for communication without buffering from among
the functions of MBCF.
In this paper, we evaluate the performance of MPI/MBCF on a cluster
of workstations with the NAS Parallel Benchmarks.
We verify whether a message passing library implemented on the shared
memory model achieves higher performance than that on the message
passing model.
