Fascinating. I have no idea how one would ensure this property when using MPI over, say, an ethernet network with multiple possible paths between two machines. But be that as it may, thanks for pointing this out -- it completely solves a problem I had perceived before. > It seems that the MPI standard authors had the same feeling. ;) :-) W. ------------------------------------------------------------------------- Wolfgang Bangerth email: [email protected] www: http://www.math.tamu.edu/~bangerth/ _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
