  NESL
       
           A parallel language loosely based on {ML},
          developed at {Carnegie Mellon University} by the {SCandAL}
          project.  NESL integrates parallel {algorithms}, {functional
          languages} and implementation techniques from the system's


          community.
       
          Nested {data parallelism} offers concise code that is easy to
          understand and debug and suits irregular data structures such
          as {trees}, {graphs} or {sparse matrices}.
       
          NESL's language based performance model is a formal way to
          calculate the "work" and "depth" of a program.  These measures
          can be related to running time on a {parallel computer}.
       
          NESL was designed to make parallel programming easy and
          portable.  Algorithms are typically more concise in NESL than
          in most other parallel programming languages and the code
          resembles high-level {pseudocode}.  This places more
          responsibility on the {compiler} and {run-time system} for
          achieving good efficiency.
       
          NESL currently runs on {Unix} {workstations}, the {IBM SP-2},
          the {Thinking Machines} {CM5}, the {Cray} {C90} and {J90}, the
          {MasPar} {MP2}, and the {Intel} {Paragon}.  Work is underway
          (April 1997) on a portable {MPI} {back end}, and an
          implementation for {symmetric multiprocessors}, such as the
          {SGI} {Power Challenge} or the {DEC} {AlphaServer}.
       
          Latest version: Release 3.1, as of 1995-11-01.
