Sorry, I just want to add 2 more things: + I tried configure with and without --enable-ft-thread but nothing changed + I also applied this patch for OpenMPI here and reinstalled but I got the same error https://svn.open-mpi.org/trac/ompi/raw-attachment/ticket/2139/v1.4-preload-part1.diff
Somebody helps? Thank you very much.
