Hi,

Since pi-WAM has two ancestors, namely pi for
pi-calculus and WAM for Warren Abstract Machine,
MIMD is especially interesting for pi-WAM .

To realize some pi-calculus fragment for example
Hoare Communicating Sequential Processes (CSP),
I will not use ADA rendez vous, but are planning

"In computer science, communicating sequential
processes (CSP) is a formal language for
describing patterns of interaction in concurrent systems

CSP was first described by Tony Hoare in a 1978 article
CSP has been practically applied in industry as a
tool for specifying and verifying the concurrent

aspects of a variety of different systems,
such as the T9000 Transputer"
https://en.wikipedia.org/wiki/Communicating_sequential_processes

to use queue. Especially bounded MPMC queues, queues
with a finite capacity that allow multiple producers
and multiple consumers. And here MIMD seems to be

brother in spirit. Just think of pi-WAM being a transputer:

"An important purpose of the feature is
to enable reliable use of programming models
such as producer-consumer within a warp"
https://stackoverflow.com/q/70987051

Will see! I do not expect Micro Penis, Ross Finlayson,
Kim Horsel, or Chris M. Thomasson be helpful in
any way. They rather represent the wall of ignorance

or misunderstanding that such a project as pi-WAM can
face, very naturally. So take my posts as Turing Tests,
to see how much brain USENETS morons have, it also

helps me doing my laboratory hygien, by doing
brainwriting. Although recently it gets a little
annoying, since I am meanwhile repeating for the

5-th time what I already wrote weeks ago.

Bye
