============================== Transfer of matrices using MPI [TOC] ============================== When matrices are to be transfered, we need a standardized sequence of elements. Without such a standardization we are unable to send a row-major matrix and to receive it as column-major matrix and vice versa. In the following we accept row-major as standard sequence for our matrices during a transfer. Exercise ======== Assume you have a matrix `A` with a row-major layout where `A.incCol() == 1` and which is to be transfered in in row-major order (per the standard defined above). Is it then possible to construct the corresponding MPI data type with one invocation of `MPI_Type_vector`? Think about this for a moment and write down your response without creating a test program. :navigate: up -> doc:index back -> doc:session06/page02 next -> doc:session06/page04
