Re: [OMPI users] No increase in performance found using two Gigabit Nics

Hi Allan, i ran hpbench on a cluster of two machines having just convetional PCI bus and i didnt find any performance improvement. On the contrary the performace degraded. I figured out it may be because conventional PCI bus (33 MHz, 32 bits) provides a bandwidth with 33x32 = 1056 Mbps, hence just

Re: [OMPI users] Two Gigabit NiCs

Hi George & Allan   First of all i would like to thanks George, for the information. I think with this i can further imporve the performance of my cluster. I was wondering if there is any manual available where all these parameters are listed out. So then i can experiment with them.   Allan i would

Thanks Brian, Thanks Michael I wanted to benchmark the communcation throughput and latency using multiple using gigabit eithernet controller. So here are the results which i want share with you all I used . OpenMPI version 1.0.2a10r9275 Hpcbench Two Dell Precision 650 workstation. The Dell Pre

[OMPI users] Using Multiple Gigabit Ethernet Interface

Hi I have been looking for information on how to use multiple Gigabit Ethernet Interface for MPI communication. So far what i have found out is i have to use mca_btl_tcp.  But what i wish to know, is what IP Address to assign to each Network Interface. I also wish to know if there will be any cha
