Dear All:

With boost MPI, I trying to ask some worker nodes to send some message to the single master node. 

I am using OpenMPI 1.3.4.

I use an array recvArray[row][column] to receive the message, which is a C++ class that contain int, member functions. 

But I got an error of 

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

[n124:126639] *** Process received signal ***

[n124:126639] Signal: Aborted (6)

[n124:126639] Signal code:  (-6)

It seems that the master cannot find enough space for the receicved message. 

But, I have decleared the recvArray<calssPackage> , which is a vector with element as my received class package. 

The error is very wierd.

When I open the recvied package, the elements are not expected numbers buy only some very large or small numbers.

Any help is appreciated.
