      """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."""
