Paragon MP Benchmark Results
As part of our evaluation of early systems, we have been benchmarking prototypes of Intel's new Paragon MP system. Each node contains two application processors and a communication processor, so the MP is both a message-passing and shared-memory multiprocessor. We have measured both message-passing performance and shared-memory performance of the Paragon MP (Dunigan, ``Beta Testing the Intel Paragon MP'', ORNL/TM-12830, 1995 (in preparation)). Other benchmarks measure performance of message-passing paradigms commonly found in scientific applications as well as network and I/O performance. Benchmarks have also been used as part of the acceptance criteria for the 2048-processor Paragon MP XPS-150 recently delivered to ORNL's Center for Computational Science ( CCS ). Message passing latency has been measured at 28 microseconds, and bandwidth for a one million byte message was measured at 154 megabytes/second. Linpack performance achieved 80.5 gigaflops on 2048 processors.
