Hi all,
I have a potential application that might fit nicely into an array of Ts
made up of Ts without external memory (well, maybe one or so with 1-2MB but all
the rest only require 4K or so on-chip). I need some answers to several
questions that would help in determining if such an array was useful for this
application:
1) Who/What/Where is the largest array of transputers using only on-chip RAM
located? Is it available for research/experimentation? From across The
Pond? (it would clearly help if it was located in the US and would be
wonderful if it was located around the Washington DC area). 1000 or more
Ts would be real nice...
2) Are there commercial boards or computers available which use only on-chip
RAM? How many per board? I remember seeing a board with 19 or so on it
(who's) for the PC. Also, didn't NOSC make a board with 19 or 32 (some
outragious number) for a PC too? Are they selling these, can I get access
to it, etc.
3) If I were to build my own system, what's the going rate on T222's or T425's
for 100+ units? I don't need floating-point, and an H1 would be an overkill.
Besides, once the H1 comes out, the prices of the older units should drop
like flies (gee, didn't I here something along this line in the discussion
on "who needs massive parallelism"?). What's the expected price of these
parts in Sept 91 or Apr 92?
4) Has anyone experienced minor or major technical problems in integrating
large numbers of Ts without external memory? I would like to know this kind
of user information in advance...
5) I just looked through the riddle section in the four latest OUG newsletters
but I didn't find the answer...Geraint, Geoff, David, (and company) are
you out there; any insights from the Oxford joke team?
Thanks

I need some answers to several Southampton has a machine with 1260 T212 chips in it, if that is of any interest. Of course you only have 2k of on-chip RAM to play with, but maybe you could still use it? I'm not sure if it can be accessed remotely. If you are interested, you could try contacting cjs@uk.ac.soton.tts, or bjp at the same address. -- I.Glendinning@ecs.soton.ac.uk Ian Glendinning Tel: +44 703 593081 Electronics and Computer Science Fax: +44 703 593045 University of Southampton SO9 5NH England
