Dear All, I am using Open MPI : mpirun (Open MPI) 1.3.4 I got error: terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::mpi::exception> >' what(): MPI_Test: MPI_ERR_TRUNCATE: message truncated I installed boost MPI library and compile and run the program by openMPI. It seems that the message has been truncated by the receiver. How can I fix the problem ? Is it a bug of OpenMPI ? Any help is appreciated.
