<version>3.0
<abstract>
NESL is a strongly-typed, functional, nested data-parallel language
developed by the SCandAL project . It is intended to be used as a portable
interface for programming a variety of parallel and vector
supercomputers, and as a basis for teaching parallel algorithms.
Parallelism is supplied through a simple set of data-parallel constructs
based on sequences (ordered sets), including a mechanism for applying
any function over the elements of a sequence in parallel and a rich set of
parallel functions that manipulate sequences.
The implementation is
based on an intermediate language called VCODE and a low-level vector
library called CVL.
The NESL front end runs on a user's workstation, while allowing the remote
execution of programs on parallel or vector supercomputers. The interactive
environment includes a library of graphics routines, profiling and tracing
facilities, and on-line documentation.
<environment>
The current release runs on
workstations, the Thinking Machines Connection Machines CM2 and
CM5, the Cray Y-MP and C90, and the MasPar MP2.
System requirements are Common Lisp, ANSI C, and
X11 (only needed for graphic output).
