Dear All: I need to transfer some messages from workers master node on MPI cluster with Open MPI. The number of messages is fixed. When I increase the number of worker nodes, 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_Unpack: MPI_ERR_TRUNCATE: message truncated[n231:45873] *** Process received signal ***[n231:45873] Signal: Aborted (6)[n231:45873] Signal code: (-6)[n231:45873] [ 0] /lib64/libpthread.so.0 [0x3c50e0e4c0][n231:45873] [ 1] /lib64/libc.so.6(gsignal+0x35) [0x3c50230215][n231:45873] [ 2] /lib64/libc.so.6(abort+0x110) [0x3c50231cc0]
-------------------------------------------------------------- For 40 workers , it works well. But for 50 workers, it got this error. The largest message size is not more then 72 bytes. Any help is appreciated. thanks Jack July 7 2010 _________________________________________________________________ The New Busy is not the too busy.
