This paper describes COLTHPF, an MPI-based run-time support for the coordination of concurrent and communicating HPF tasks. COLTHPF is conceived for use by a compiler of a high-level coordination language to structure a set of data-parallel HPF tasks according to popular forms of task-parallelism. Since it requires only small changes to the run-time support of the HPF compiler used, COLTHPF is easily portable among different compilation systems. The paper outlines design and implementation issues, and reports the results of experiments conducted on an SGI/Cray T3E.
