I have a setup where one process is responsible for distributing jobs

Now for example I want to enable communication between the master

Is stdin/stdout suitable? (is sending binary data a problem with this

say anything about the use of stdin/stdout. Is it safe to assume that
most 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?
