I am having some problems getting boost::mpi working with our local installation of openmpi 1.2.3 here at Los Alamos. I am able to send POD's through the interface, but it fails sending anything more complicated (i.e. std::string). Have I missed some step in the process? I get the following error when I tried the 2nd example from the on-line Tutorial ... terminate called after throwing an instance of 'boost::exception_detail::clone_implboost::mpi::exception

' what(): MPI_Alloc_mem: MPI_ERR_NO_MEM: out of memory

Also, I was unable to build a single threaded version of libboost_mpi which struck me as odd. Any assistance would be greatly appreciated. compiler: g++ (GCC) 3.4.5 20051201 (Red Hat 3.4.5-2) Using... /usr/projects/mcatk/packages/lib/libboost_mpi-gcc34-mt-1_36.so.1.36.0
