Organization: University of Passau, Germany Date: 29 Jan 97 08:05:31 GMT Message-ID: <32ef04cb.0@news.rz.uni-passau.de> Hi, I wonder, whether there is a collective communication primitive which does a cyclic shift (rotation) of data between processors of one group? Such kind of data exchange is used, e.g., for matrix multiplication. If there is no such operation in MPI-1, is it planned for MPI-2? Thanks, Sergei
