Hello I have a question, when i do many MPI_Alltoall in my program always the first MPI_Alltoall take too much time to be done. I don't know where the first communication is always expensive. Is that a problem of memory??????? thanks. __________________________________ Do you Yahoo!? Yahoo! Small Business - Try our new resources site! http://smallbusiness.yahoo.com/resources/
