Re: [Boost-users] [Boost.Asio] Compiling Boost.Asio with OpenMPI

Have you checked which compiler, compiler and linker options the mpicxx script uses? Maybe one of those is causing your problems Matthias On 15 Feb 2010, at 01:41, vibhor aggarwal wrote:

Hi,

I have tried compiling with mpicxx and no MPI code in it. It compiles fine, but I still have to use mpirun to executed the generated binary and it does a connection time out.

Kind Regards Vibhor

Hello,

I am trying to write a program which runs using OpenMPI on our cluster and communicates the results using TCP/IP to another machine which has a network connection to the cluster. I am using Boost.Asio for the TCP/IP connection. If I remove the MPI code from the executable and compile it with g++, it connects to the remote machine without a problem. But when I add a simple MPI code to it and compile with mpicxx and execute using mpirun, it generates a connection time out in the call to socket.connect(). Any idea what might be going wrong ?

Have you tried compiling it with mpicxx without adding any MPI code to it?

Matthias
