Abstract
The work presents a set of abstract communication benchmarks designed
to test the basic communication capabilities and more advanced
communication schemes of various commercial parallel computer systems.
The benchmark package consists of seven programs measuring the basic
communication parameters and three benchmarks relevant for out
real-time application, a (second-level) trigger system for the ATLAS
experiment.
A wide number of results of new generation parallel systems will be
presented, including Digital Memory Channel clusters, Cray T3E
parallel system, Silicon Graphics Origin2, Parsytec CC, Meiko CS2 and
IBM SP2.
From these results conclusions about the limitations of the various
architectures and implementations are drawn. Additionally, the
suitability of the various implementations for the trigger
applications is discussed. Ongoing and future work including more
realistic traffic patterns for trigger applications is briefly
reviewed.
