At the hardware level we do have message passing between a
processor and the memory controller -- this is exactly the
same as talking to a shared server and has the same issues of
scaling etc. If you have very few clients, a single shared
server is indeed a cost effective solution.

The misinterpretation of Moore's Law is to blame here, of course: Moore
is a smart guy and he was talking about transistor density, but pop culture
made is sound like he was talking speed up. For some time the two were
in lock-step. Not anymore.

XXX is any program I am trying to run from ape/psh.
Has anyone else run into this recently?
it all works for me.

I believe that if you build a new binary from the sources
instead of using the pre-compiled binary, this bug is fixed.
The binaries are lagging behind the actual source code.

confusion reigns. People I thought I was giving a ride to are coming
in at different times.
So, let's try again.
I have one rider: maht.
I can take two more. Roger?
Anyway I get in 835PM on the 20th, I can take 2 people besides maht,
so let me know.

I would use a pipelining + divide-and-conquer approach, with some RAM on chip.
Units would be smaller than a 6502, more like an adder.
you mean like the Thinking Machines CM-1 and CM-2?
it's not like it hasn't been done before :)
what changed recently?
not drawterm.
no. not drawterm. not the video card.
i've recently upgraded x.

Another embarrassingly parallel problem, as Sam Watkins pointed out, arises

The pipelining + divide-and-conquer method which I would use for parallel

But why'd you assume people in the wrong (w.r.t. their understanding
