That was ten years ago - do you have any idea as to how things have
been progressing in this area since then?

I agree with this. My approach is in the same space as OpenMP - a
simple way for users to define shared memory parallelism. There is no
reason why it would not work with multiple disks or IO ports on the
same shared memory server. However for di
s with
garbage collection in multi-threaded applications. Without it the
reference count method is prone to race conditions. However it seems
like a fairly crude mechanism to solve this problem. Individual
semaphores could be used for each object reference counter, as in
Java.

. I like the simplicity of OpenMP,
the cross-language portability of MPI and the fact the concurrency is
built in to the Occam language. What I am proposing here is a hybrid
of the OpenMP and Occam approaches - a change to the language which is
very natural and yet is easy for programmers to understand.
Concurrency is generally regarded as the hardest concept for
programmers to grasp.

the boundary values are stored in temporary variables until they can

e of this would be possible with the current implementation
of Python with its Global Interpreter Lock, which effectively rules
out true parallel processing.

What do others think?
