Thank you. At the URL I simply moved the 2 arguments for main signature, ie int main(int argc, char *argv[]) { ... } and both mpicc and mpiCC generated an executeable for mpirun. But mpiCC obviously does not like int main(argc, argv) int argc; char *argv[]; { ... } ________________________________ From: boost-users-bounces@lists.boost.org [boost-users-bounces@lists.boost.org] on behalf of Jeremiah Willcock [jewillco@osl.iu.edu] Sent: Wednesday, November 30, 2011 9:23 AM To: boost-users@lists.boost.org Subject: Re: [Boost-users] FW: BGL, MPI On Wed, 30 Nov 2011, Neiderer, Andrew M USA CIV (US) wrote:
With lots of help I think I am getting close to a "hello, world" BGL, MPI example to execute.
Not sure about the error I am getting from execution
I can't tell what you are getting the segmentation fault from. Does a C MPI program work (like the one from http://www.dartmouth.edu/~rc/classes/intro_mpi/hello_world_ex.html) work? If not, see the documentation for your MPI implementation (these types of problems in C MPI code are often due to mismatched software versions). -- Jeremiah Willcock
