Hello. Our cluster consists of P-III 850MHz dual-SMP nodes, and I'm testing VIGM on Myrinet NIC M2L-PCI64B. According to our measurement using the pingpong program in VIGM source tree, the latency shows 62 us for 4bytes messages (not the round-trip latency). I think it's terrible. :( Could anybody tell me the true latency of VIGM? I'm afraid of having a mistake to measure the latency. While I have tried to find out the performance of VIGM over the internet, it was not easy. Thanks in advance... p.s. the bandwidth data would also be appreciated. ------------Korea Advanced Institute of Science and Technology------------- Moon-Sang Lee [email protected] CS dept.
