I used --with-libnuma=/usr since Prentice Bisbal's suggestion and it worked. Unfortunately, I found no way to fix the failure in finding libimf.so when compiling openmpi-1.3.1 with intels, as you have seen in other e-mail from me. And gnu compilers (which work well with both openmpi and the slower code of my application) are defeated by the faster code of my application. With limited hardware resources, I must rely on that 40% speeding up.
My post how to implement the -rpath flag, which should fix the libimf.so problem, has found no answer. And i found no help through google. If you have a suggestion on that it would be great. I was referring to the following notes: "However, dynamic linkage is also a headache in that the mechanisms used to find shared libraries during dynamic loading are not all that robust on Linux systems running MPICH or other MPI packages. Typically the LOAD_LIBRARY_PATH environment variable will be used to find shared libraries during loading, but this variable is not reliably propagated to all processes. For this reason, for the compilers that use compiler shared libraries (ifort, pathscale), we use LD_LIBRARY_PATH during configuration to set an -rpath linkage option, which is reliably available in the executable. This works well as long as you insure that the path is the same for all machines running pmemd. Earlier versions of ifort actually also set -rpath, but this was dropped due to confusing error messages when ifort is executed without arguments." thanks francesco On Wed, Apr 15, 2009 at 1:04 PM, Jeff Squyres <jsquy...@cisco.com> wrote: > On Apr 6, 2009, at 4:24 PM, Prentice Bisbal wrote: > >> > I would appreciate help in circumventing the problem. >> >> I believe you need >> >> --with-libnuma=/usr. >> > > > Sorry for the late reply. > > FWIW, the above is correct -- you should use --with-libnuma=/usr, not > --with-libnuma=/usr/lib. > > Please also note in this thread: > > http://www.open-mpi.org/community/lists/users/2009/04/8853.php > > We found some obscure logic issues with the handling of --with-libnuma.
