Someone asked earlier in this thread -- I've used RHEL4.4 and RHEL5.4 on my Nehalem EP boxen. I used the default gcc on those RHELs for compiling everything (OMPI + apps). I don't remember what it was on RHEL 4.4, but on RHEL 5.4, it's GCC 4.1.2. > You and Jeff reported that your > Nehalems get along with Open MPI. > I would guess other people have functional Open MPI + Nehalem systems. > All I can think of is that some mess with the OS/gcc is causing > the trouble here. I don't have much experience with kernels outside of the RHEL kernels, so I don't know if 2.6.32 is problematic or not. :-( -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
