    """The HPX-5 Runtime System. HPX-5 (High Performance ParalleX) is an
    open source, portable, performance-oriented runtime developed at
    CREST (Indiana University). HPX-5 provides a distributed
    programming model allowing programs to run unmodified on systems
    from a single SMP to large clusters and supercomputers with
    thousands of nodes. HPX-5 supports a wide variety of Intel and ARM
    platforms. It is being used by a broad range of scientific
    applications enabling scientists to write code that performs and
    scales better than contemporary runtimes."""
