HI,<div><br></div><div>I am involved in a project which requires the transport of large C++ instances over MPI communication channels. I am using boost serialization to pack and unpack the objects into a buffer. The whole buffer is sent in one shot.</div>
<div><br></div><div>Of course for large objects this can be problematic. I have two questions...</div><div><br></div><div>1) is there any way to tell beforehand how large the buffer needs to be? In other words, can you run serialization in a counting only mode?</div>
<div>2) is there an archive implemented which streams across MPI communication channels (not sure this is the right terminology.)? Seems like it might be useful. This might be a better question for the boost MPI team, though.</div>
<div><br></div><div>Thanks,</div><div><br></div><div>Jon</div>
