PSPVM: implementing PVM on a high-speed interconnect for workstation clusters

摘要

PSPVM in an implementationof the PVM package on top of ParaStations high-speed interconnent for workstation clusters. The ParaStation system uses user level communication for message exchange and removes the operating system from the critical path of message transmission. ParaStations user interface consists of a user-level socket emulation. Thus, we need only minor changes to the standard PVM package to get it running on the ParaStation system. Throughput of the PSPVM is increased eitht times and latency is reduced by a factor of four compared to regular PVM. The remaining latency is mainly (88
