[OMPI users] v1.2 Bus Error (/tmp usage)

Good Day, I'm using Open MPI on a diskless cluster (/tmp is part of a 1m ramdisk), and I found that after upgrading from v1.1.4 to v1.2 that jobs using np > 4 would fail to start during MPI_Init, due to what appears to be a lack of space in /tmp. The error output is: - [tpb200:32193] *

Re: [OMPI users] error for open-mpi application

However, when I used openmpi to compile a application program( Molecular dynamcis code: Amber9), error messages are given: I think you would be better off using the OpenMPI wrapper compilers rather than trying to link the mpi libraries by hand. For mo re information read the FAQ, which contain

Re: [OMPI users] Intel EM64T Compiler error on Opteron

FWIW, I know that we saw similar issues with the Intel 8.1 series (segv's during compilation). Since we are not doing anything illegal in terms of C++, we already treated this as a compiler bug that we couldn't really do much about. Plus, we [perhaps incorrectly] assumed that most sites using th
