Exploiting Gigabit Ethernet capacity for cluster applications

摘要: In this paper we report about the recently completed porting of GAMMA to Netgear GA621 Gigabit Ethernet adapter, and provide a comparison among GAMMA, MPI/GAMMA, TCP/IP MPICH/TCP, based on older GA620 network adapters using different device drivers, in cluster PC running Linux 2.4. (the Genoa Active Message Machine) is lightweight messaging system an active message-like paradigm, originally designed for efficient exploitation Fast interconnects. The includes simple latency/bandwidth evaluation systems both adapters, as well performance comparisons NAS Parallel Benchmarks end-user fluid dynamics application called Modular Ocean Model (MOM). analysis results provides useful hints concerning use with clusters PC. particular, it emerges that combination low end-to-end latency (8.5 /spl mu/s) high throughput (118.4 MByte/s), performing, cost-effective alternative proprietary high-speed networks, e.g. Myrinet, wide range computing applications.
