Are all RHEL 5 and SLES 10 (SPx) up to being "patchless" level for clients?

Not if you do not supply RDAC (mpp) kernels, too, e.g. for 6140? > RHEL5 (and thus CentOS 5) comes with an OFED stack included in the OS.

So, IOW, 1.6 5 will work with OFED I/B compliant hardware "out of > the box" You need to supply SRPMS/src too as some people (like Hillsboro HPC benchmark) need to produce compatible PathScale/INTEL/PGI MPI versions (and maybe gcc if you don't build that per OS/gcc release level). Also the comments (above) about mpp (RDAC) apply - you'd need modules built against that.
