You repeat on the simple bulk jobs in sci computing where a file batch interface is enough:
Process X works on input file Y and writes output to file Z. A manager script collects the results and creates a gnuplot diagramm.
Such things of course would not raise the question of this discussion. Not even the question of threads at all and MPI ...
