Could you explain what you mean by "comm accept/connect" ? jodyOn Tue, Mar 25, 2008 at 4:06 PM, George Bosilca <bosi...@eecs.utk.edu> wrote:There is a chapter in the MPI standard about this. Usually, people will use comm accept/connect to do such kind of things. No need to have your own communication protocol. george.

BasicallyI have a setup where one process is responsible for distributing jobsto other mpi processes and collecting the respective results afterwards. Now for example I want to enable communication between the master process and a GUI application. The GUI should be notified by the master about progress being made and it should also be possible for the GUI to send commands to the master (so the communication should be possible in both ways)Is stdin/stdout suitable? (is sending binary data a problem with thistype of communication?) I also read that the MPI specification does notsay anything about the use of stdin/stdout. Is it safe to assume thatmost common MPI implementations support it? Another way to deal with the problem would be to write some custom network code that is used alongside the MPI communication. What is commonly used in this situation?
