  Description     : Grid-enabled implementation of MPI

  MC-MPI is a Grid-enabled implementation of MPI, developed by Hideo
  Saito at the University of Tokyo.  Its main features include the
  following:
  - [Firewall and NAT traversal]: MC-MPI constructs an overlay
    network, allowing nodes behind firewalls and nodes without global
    IP addresses to participate in computations.  There is no need to
    perform maual configuration; MC-MPI automatically probes
    connectivity, selects which connections to establish, and performs
    routing.
  - [Locality-aware connection management]: Establishing too many
    connections, especially wide-area connections, results in many
    problems, including but not limited to the follwing: exhaustion of
    system resources (e.g., file descriptors, memory), high message
    reception overhead, and congestion between clusters during
    all-to-all communication.  Therefore, MC-MPI limits the number of
    connections that are established.  If we assume, for simplicity,
    that n processes are distributed equally among c clusters, then at
    most O(log n) connections are established by each process and at
    most O(n log c) connections are established between clusters.  As
    MC-MPI uses a lazy connect strategy, fewer connections are
    established for applications in which few process pairs
    communicate.  The maximum number of connections allowed can be
    controlled by passing the -beta option to mpirun (see Subsection 3).
  - [Locality-aware rank assignment]: Temporarily disabled in this
    version.
