Hello, I have been using the MYRICOM 10Gb card in my NFS server (head node) for the Beowulf cluster. And it works well. I have a inexpensive 3Com switch (3870) with 48 1Gb ports that has a 10Gb port in it and I connect the NFS server to that port. The switch does have small fans in it.
I had to compile the driver and patch the Linux kernel (RedHat Enterprise 4U4). There are tuning parameters, some of which I have tried and some which I have not (Don't break it if it works well... ) It'd been running well for 4 months now. My internal cluster benchmarks ( parallel Quantum mechanics programs ) improved by about 20% with disk backups improving by 60%. Pretty much everything that uses MPI runs faster since the NFS server network usage is a smaller percentage of the network wall clock time. I think the 10Gb link to the NFS server is a effective upgrade component of a beowulf cluster if one is using 1Gb ethernet, MPI and NFS. ------ Sincerely, Tom Pierce Mark Hahn <[EMAIL PROTECTED]> Sent by: [EMAIL PROTECTED] 02/20/2007 03:25 PM To Beowulf Mailing List <[email protected]> cc Subject [Beowulf] anyone using 10gbaseT? Hi Beowulfers, have you had any experience using 10gbaseT yet? I happened on a media story about how quite a few vendors have recently intro'd support for it. the only nics mentioned were the heavyweight encumbered-with-TOE kind - on them at least, the article mentioned 20-25W dissipation. (which doesn't seem like a big deal - about a disk and a half, fraction of a cpu, or a tenth of a GPU :) anyway, I'm interested to hear if anyone's played with 10gbaseT (or 10G clusters in general)... thanks, mark hahn. _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
