Hi there,
i have a big problem by running MPI programs which use the Boost.MPI library. When i'm trying to run programs on more than one node, collective operations like environment
destructor (cause of FINALIZE, which is colletive) causing the programm to crash. I got errors like this :
[1]terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::mpi::exception> >'
[1] what(): MPI_Barrier: Other MPI error, error stack:
[1]PMPI_Barrier(362).................: MPI_Barrier(MPI_COMM_WORLD) failed
[1]MPIR_Barrier_impl(255)............:
[1]MPIR_Barrier_intra(79)............:
[1]MPIC_Sendrecv(186)................:
[1]MPIC_Wait(534)....................:
[1]MPIDI_CH3I_Progress(184)..........:
[1]MPID_nem_mpich2_blocking_recv(895):
[1]MPID_nem_tcp_connpoll(1746).......: Communication error with rank 0:
I also tested this with the simple broadcast example from the Boost.MPI tutorial - same errors..
But when using the original MPI equivalent without the Boost.MPI library, such as MPI_Barrier, the programm runs well. I am using MPICH2 on Ubuntu 10.04 platforms.
Someone had problems like this or know a fix for that?
