Abstract
The interconnection networks and the communication
system software in clusters of multiprocessors are critical
to achieving high performance. Recently, Sun
Microsystems has introduced a new system area network,
Sun Fire Link interconnect, for its Sun Fire cluster systems
with some performance results at the MPI level. Sun Fire
Link is a memory-based interconnect with layered system
software components that implements a mechanism for
user-level messaging based on direct-access to remote
memory regions of other nodes. This is referred to as
Remote Shared Memory (RSM). This paper assesses the
performance of the interconnect at the RSM level, as well
as MPI level. We present the performance of different
