language A parallel language loosely based on ML,
developed at Carnegie Mellon University by the SCandAL
project. NESL integrates parallel algorithms, functionallanguages 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.
