Subject: Re: [OMPI users] open-mpi on Mac OS 10.9 (Mavericks)
From: George Bosilca (bosilca_at_[hidden])

$ /usr/bin/gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin13.0.0
Thread model: posix

The other thing that can go wrong is the configuration of the interfaces that allow different pro cesses to communicate together. Let’s se what the default is on your machine. Can you report the output of the two following commands:
ompi_info —param oob tcp —level 9
ompi_info —param btl tcp —level 9

Another thing you can try is to manually set the interface to be used. I would try lo0, en0 or en1 (if available). You can set oob_tcp_if_include and btl_tcp_if_include to one of these values to see what is happening.

The code compiles fine, but when running the examples for openmpi-1.7.3, the code hangs in MPI::Init() and never returns. No error message. No warning. It just hangs. If I compile in debug mode and do a stack trace, it shows that it is stalled inside of MPI::Init() every time. Has anyone been able to successfully get openmpi working on 10.9? If so, what, if anything, are you doing differently?
