You will be running the MPI program/ Benchmark and comparing standard TCP sockets over 1GbE vs RDMA with softRoCE over 1GbE.<br /><br />Note that i would suggest that you run pure network benchmark first in order to compare the performance and also identify potential limitation early.

But without fail, most customers' buying habits are conservative and incremental. It's the wise company that *talks* roadmap, but delivers the incremental improvements that customers want.Ken Oestreichhttps://www.blogger.com/profile/13530514227192850735noreply@blogger.comtag:blogger.com,1999:blog-2870646295897747163.post-10952107089862734932009-12-14T13:47:46.740+00:002009-12-14T13:47:46.740+00:00This comment has been removed by a blog administrator.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2870646295897747163.post-4844432838172048582009-11-18T04:56:44.013+00:002009-11-18T04:56:44.013+00:00This comment has been removed by a blog administrator.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2870646295897747163.post-46027499319818539462009-01-19T02:49:00.000+00:002009-01-19T02:49:00.000+00:00Everyone should be using a "green" hosting company...Everyone should be using a "green" hosting company.
