I have a class whose data I want to send/recv and which are of type std::vector. However, once it’s allocated the size of this vector is fixed during runtime. Can I use BOOST_IS_MPI_DATATYPE to speed up data transfer and how would I do it

Hi Sven This is exactly the usage scenario for the skeleton&contents mechanism. Once the vector is allocated you can just send the "content", which is a custom MPI datatype for the data in the vector. Matthias
