All, I had a similar problem as James described in an earlier message: http://www.open-mpi.org/community/lists/users/2008/07/6204.php While he was able to recompile openmpi to solve the problem, I had no luck with my RedHat Enterprise 5 system. Here are two other threads with similar issues regarding openmpi on Ubuntu and OSX which were solved: https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/234837 http://www.somewhereville.com/?cat=55
Now... Here is my story: I had Quantum Espresso (QE) running without problem using openmpi. However, when I tried to recompile QE with a recompiled fftw-2.1.5, it compiled without any error. But when I ran QE, it gave me the error below: *** Process received signal *** Signal: Segmentation fault (11) Signal code: Address not mapped (1) Failing at address: 0x22071b70 [ 0] /lib64/libpthread.so.0 [0x352420de70] [ 1] /usr/lib64/liblapack.so.3(dsytf2_+0xc43) [0x2aaaaac9f5e3] [ 2] /usr/lib64/liblapack.so.3(dsytrf_+0x407) [0x2aaaaaca0567] [ 3] /opt/espresso-4.0.1/bin/pw.x(mix_rho_+0x828) [0x5044b8] [ 4] /opt/espresso-4.0.1/bin/pw.x(electrons_+0xb37) [0x4eae47] [ 5] /opt/espresso-4.0.1/bin/pw.x(MAIN__+0xbf) [0x42b3af] [ 6] /opt/espresso-4.0.1/bin/pw.x(main+0xe) [0x6aad5e] [ 7] /lib64/libc.so.6(__libc_start_main+0xf4) [0x352361d8a4] [ 8] /opt/espresso-4.0.1/bin/pw.x [0x42b239] *** End of error message *** >From what I read from the above links, it seems to be a bug in openmpi. Please share your thoughts on this, thank you! CY
