lam-runtime binary package in Ubuntu Bionic amd64

 LAM (Local Area Multicomputer) is an open source implementation of the
 Message Passing Interface (MPI) standard.
 .
 Some enhancements in LAM 6.3 are:
  o Added the MPI-2 C++ bindings package (chapter 10 from the MPI-2
      standard) from the Laboratory for Scientific Computing at the
      University of Notre Dame.
  o Added ROMIO MPI I/O package (chapter 9 from the MPI-2 standard)
      from the Argonne National Laboratory.
  o Pseudo-tty support for remote IO (e.g., line buffered output).
  o Ability to pass environment variables through mpirun.
  o Ability to mpirun shell scripts/debuggers/etc. (that eventually
      run LAM/MPI programs).
  o Ability to execute non-MPI programs across the multicomputer.
  o Added configurable ability to zero-fill internal LAM buffers
      before they are used (for development tools such as Purify).
  o Greatly expanded error messages; provided for customizable
      local help files.
  o Expanded and updated documentation.
  o Various bug fixes and minor enhancements.
