OpenMP and parallel programming languages

Hello folks,

Does anyone know any explicit parellel programming languages? C/C++
and Fortran support OpenMP directives. Any one has tried to extend
C/C++ grammar to include OpenMP.

Cheers,
Neal

There's Occam, I think.  The Kent Retargetable Occam Compiler is one
modern implementation:

http://www.cs.kent.ac.uk/projects/ofa/kroc/

There's also the Newsqueak programming language invented by Rob Pike:

and the Limbo programming language Pike also co-developed for the
Inferno operating system:

Fortran 95 was a fairly minor revision of Fortran 90, but it did add
some features from High Performance Fortran to facilitate the
expression of parallel algorithms: PURE and ELEMENTAL functions, and
the WHERE and FORALL constructd. Co-Array Fortran (see
http://www.co-array.org/ ) is an extension of Fortran 95.

Occam has parallelism in its design (based an CSP).  ADA has the
tasking concept.  Data flow languages are also inherently parallel.
Verilog and VHDL and all other hardware description languages describe
hardware objects that all run in parallel.

Java.  The parallelism is expressed via threads.

Ada 95 has a developed parallel computing model:

- tasks represent scheduling items. They have rendezvous, which support
queuing, parameter passing and concurrent exception handling.

- protected objects provide passive shared ADT, with read-only (functions),
read-write (procedures) and queued (entries) ways of accessing its
internals.

- blocking requests can be requeued between entries of the protected
objects and tasks.

I've just started looking at Handel-C.  It's used for hardware/software
co-design and is pretty much a superset of C.  It has a 'par' (parallel)
construct at least - I'm sure I saw some semaphore primitives somewhere
too.

Some docs at:
http://www.celoxica.com/techlib/def...tID=9&CatType=2
(useful ones about half-way down)

ImpulseC looks like a similar idea based on a quick glance, but I haven't
looked properly.

there have been several explicitly pareallel C dialects. Data-parallel C
languages include
C* for the Connection Machines
http://burks.brighton.ac.uk/burks/foldoc/97/15.htm
and its derivative, Data-parallel C
http://burks.brighton.ac.uk/burks/foldoc/81/28.htm
more recently, Cilk
http://supertech.lcs.mit.edu/cilk/
and split-C
http://www.cs.berkeley.edu/projects...castle/split-c/

None of these includes OpenMP directly, though.

Modula-3 has thread support builtin to the language, with more
stuff available by direct calls to the RTS, in the existing
implementations.  www.m3.org.
