Hello everybody from wet and dreary Manchester (UK).

Has anybody out there developed a model to predict the time taken by any given occam
program (not much to ask for !!! :-)

Any info on any aspect regarding timing, prediction of times etc for (occam) progs on
transputers would be MOST welcome.

Hi, there,

Does anybody if there is any stadnard benchmarks people use to measure the
performance of transputer?  or is there any parallelized benchmark, like
SPECmark ?

Thanks.

	I am currently involoved in a project using transputers to
control a simple robot arm. The project involves designing an building a
control system which uses a a transputer per motor on the robot (the motors
are driven using pulse width modulation). I have already designed and partly
constructed a circuit to control one motor and once this is has been tested
I will expand the system to control the entire robot (I am using the IMST212
as it is cheap for prototyping).
	I know that there are people out there who will say why are you
using transputers instead of a micro-controller but this is firstly a
project with transputers and then a project in robotics.
	What I am interested in knowing is if there is anyone else out
there who is trying/has tried a similar project. All of the previously
documented research I have seen have used transputers to only do position
calculations etc, and have not used them to actually provide input to motors,
process interrupts etc.

Well having just returned from NATUG 5, I have some comments, questions and
concerns.

All in all it was a good conference with many interesting papers on a wide
variety of subjects.  Mr. Veronis et. al. did a splendid job putting things 
together.  But I have one question....WHERE WAS SGS-THOMPSON??? I asked 
Dave Fielding about it and was told that they had promised to be there 
after two month's of Dave's prodding. (My hat's off to Dave for 
perserverance.)  But still no SGS-Thompson.  I cannot help to wonder if we 
were avoided.  After all the T9000 is not out yet and may not be the hit 
SGST had hoped it would have been when it does arrive.  Texas Instruments 
was there describing their TMS320C40 DSP.  Granted it is not in final 
production yet but at least there is first silicon to be had.  If this is 
going to be a regular practice for Thompson, then maybe the 'T' in NATUG 
should be re-evaluated.

Greetings!

A number of us are working with Parytec INMOS Transputers (T8) on a SUN 4
workstation.  The transputer board has a VME Bus.  Currently we are cursed
with mtools, an incredibly tedious programming environment.

What we would like to do is use gcc or cc and link our code to existing
libraries in order to use the transputers or, failing that, assemble or
compile the transputer code into *.o files seperately and link using
the traditional c or fortran linkers.  We would like to never see mtools
again!  Does anyone know of any c or fortran linkable libraries/device
drivers for such a beast?  Commercial references would be interesting, but
as the University is currently poor (Thanks Gov. Edger!) PD or Shareware
(ftp-able) sources would be even more appreciated, as we could start using
them right away!

Thanks for any and all help with this!

We, three students at Utrecht University, are currently working on a
debugging/performance analysis program for transputer networks. It looks
something like this.
Each node that runs an application program has a shadow node that logs
events from the application node over a dedicated link. (so when using our
program, you can use only half of the network, and only 3 links per
transputer.) We have a 16 transputer network here at our university.

Our program is written in C that is compiled with the Logical Systems
Toolset, Version 89.1c.
If you have an application that can be compiled in this way, and you are
willing to let us use it to test our program, please mail us! Thanks in

Double-your-money, a holiday in greece and a cuddly toy to acorn for the new
font manager. Someone posted up that the new font manager is more memory
efficient than the last one, as well as faster. No bloody kidding! I can now
zoom in and out of a document with headlines and diagrams with multiple
multi-size fonts, all on a font cache of about 64K! It's SOOOOO Fast! An amiga
owning friend of mine (mentioned in another post) told another friend of mine
that Impression must have been cheating by rendering the page as a bitmap and
scrolling that around, and that was on the old arm2 310.... On RO3 the part of
the font drawing procedure that takes the most time is the loading from disc!
I have never seen the hourglass while font rendering, it doesn't have enough
time to appear.

And now you can use all fonts with postscript printers as the postscript
printer driver will automatically download the font definitions to the printer
if the printer does not have the font. Pity the printer I have access to is an
ancient apple laserwriter, which won't take them!

Can't have everything in life I suppose....

I was wondering what different peoples expreriences with the various
(well two) basic compilers that are available, ie. ABC and RiscBASIC
(I think they're the only two). The only reviews I have of these are
well over a year old (probably two) and certainly ABC will have
changed since then, 'cos it was only version 2 then.

I notice that quite a few things that are floating around the PD
places are compiled with ABC, and so I began to think there must be
something in it (but as far as I know it is more difficult to tell if
something was compiled with RiscBASIC due to the fact that it does not
have a module library). 

As far as I recall ABC (then) came out the worse of the two both in
speed and the fact that it could not handle some of Basic V's features
(eg. the new array stuff, plus matrix stuff).

Any comments anyone has on either of these compilers (or any I might
not have heard about) will be gratefully received.

In fact you can format an 800k disc as a 1.6M disc, it won't moan at
you as it totally disreguards the extra notch on the disc. Although
I've never tried it it is mentioned in the user guide somewhere, but
not recomended (for obvious reasons).

But would acorn want to lose such sales?  Personally it's going to be a *long*
time before I can afford to buy an Acorn SCSI interface and then the *acorn*
scsi drive with RISCiX on it.  This combination currently represents about
A$3000 or 100% of what I paid for my arc!  These prices are a joke!
I suspect acorn is used to supplying to the education community which can
"afford" (note quotes) exorbitant prices.  Unfortunately this tends to leave
the rest of us out in the cold :-(

From what I've heard of the speed of RISCiX, I don't think RISCOS is in any
danger of becoming obsolete.  Besides, you can run RISCOS and RISCiX on the
same machine - though not concurrently.
