You need to post more details about the context, otherwise all one can
say is that there was some error establishing a TCP connection (one
host tried to connect to another, and this one did not respond before
time run out).

It appears that you are using OpenMPI and the problem originates in
the OpenMPI layer -it's apparently not a Boost::MPI coding problem- so
you might get more help if you ask on the OpenMPI users mailing list.

Regards,
Riccardo
