What's a DAP, anyway?
Well the ICL
ones were early parallel machines (DAP = Distributed Array
Processor if I remember right).
So its like... a hardware systolic array?
I mean, its like a peripheral for something like a PDP-11? Or can it
be hooked up to anything?
My memory's too fuzzy I'm afraid - I used to use the Meiko which replaced the
DAP at uni (about 140 T800 processors I think - replaced in the mid 90's with
a Parsys box that had a pile of T9000's inside). Google suggests that the
original DAP was a 4096 array of single-bit processors, but I'm not convinced
about that - I've got a hazy memory of a machine with about 40 processors, but
that may have been something else! :-) (Kent uni seemed to be something of a
UK centre for parallel computing research back then)
Google also says that the DAP was an add-on for an ICL 2900 series mainframe.
That is possible; there was a 2900 at Kent once although it was all gone by
the time I was there; some notes I have found say that the DAP was using a Sun
box as the front end in the early 90's.
I'll have another dig around tomorrow as I'm sure I should have some
background info on the machine *somewhere*...
cheers
