I'm the OP. It might be naive but I don't think it's ridiculous, for two reasons: 1) When I install CentOS 5 (and RHEL 5 I guess, although I've never installed it) one of the choices I'm given is whether I want to install OFED. 2) At the Open Fabrics Conference last month a talk was given (see #1 below) that discussed what version of OFED was going to be in what version of RHEL. So, people much much wiser than me are telling me that some distribution of OFED is contained in RHEL. I'm the first to admit that I really don't know what that means since I'm very new to IB. > OFED is a > distribution of RDMA software, with the kernel as one of its main > upstream sources.

When I looked at an OFED 1.4 release, I saw a ton of stuff that didn't look like it had much to do with RDMA. For example, consider all the commands whose name begins with "ib". The reason I asked this in the first place is that the cluster software package I use, Rocks, needs help in how it supports IB. I was trying to do something about this. One approach would be to just use whatever comes with RHEL, but the talk mentioned below doesn't say anything about what version of OFED this will be. Getting up to speed with IB sure is difficult. #1 http://www.openfabrics.org/archives/spring2010sonoma/Tuesday/11.30%20Tziporet%20Koren%20OFED%20Linux%20Next%20Steps/2010-03-16-11.30-OFED_For_Linux_4.pptx Cordially, -- Jon Forrest Research Computing Support College of Chemistry 173 Tan Hall University of California Berkeley Berkeley, CA 94720-1460 510-643-1032 jlforr...@berkeley.edu _______________________________________________ ewg mailing list ewg@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ewg
