Hi Jack,
Without seeing the relevant part of your program we cannot help.

Dear All:
I need to transfer some messages from workers master node on MPI cluster with Open MPI.
I use boost MPI API in my program.
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
