NESL 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. {Home (http://www.cs.cmu.edu/afs/cs.cmu.edu/project/scandal/public/www/nesl.html)}.
