Gustavo: Does this imply that a compilation with "--with-libnuma=/usr/lib64" may afford better performance?
Am asking that because in the meantime I have taken previous compilation of openmpi-1.2.6 and use it (one disk of raid1 died and I changed both with larger ones). If better performance I can try to replace openmpi with the latest version and libnuma pointing to 64. thanks francesco On Thu, Apr 2, 2009 at 6:10 PM, Gus Correa <g...@ldeo.columbia.edu> wrote: > Hi Francesco, list > > Francesco: > Besides the typo that Jeff found on your > CXX definition, I would guess you want > --with-libnuma=/usr/lib64 > (since your machine is amd64, > and you are using the 64-bit Intel compilers: cce, fce). > That is instead of --with-libnuma=/usr/lib (32-bit). > The /usr/lib64 path also works for other extra libraries > (e.g. Torque, Infiniband) on Linux x86_64. > > This is what I used on our AMD x86_64 with CentOS 5.2, and it works. > > My two cents, > Gus Correa > --------------------------------------------------------------------- > Gustavo Correa > Lamont-Doherty Earth Observatory - Columbia University > Palisades, NY, 10964-8000 - USA > --------------------------------------------------------------------- > > Jeff Squyres wrote: >> >> On Apr 2, 2009, at 7:21 AM, Francesco Pietra wrote: >> >>> Hi: >>> With debian linux amd64 lenny I tried to install openmpi-1.3.1 instead >>> of using the executables openmpi-1.2.6 of previous disks.
