First off, I have no relation to Logical Systems other than being a satisfied
customer for the following reason:

Some four months ago I posted an inquiry about C compilers for the Transputer.
I was in great need, because I had a physics application ( a Monte Carlo
simulation ) that had to be run for about a month on our 16 T414-s to get
results for the March meeting of the American Physical Society. I called up
a number of vendors, but none of them could deliver immediately ( I wanted
a stand alone development system, because by this time I really hated TDS ).
I got a beta release from Kirk (bought it of course). This came in two days,
and after one single call about the network loader I was able to port my whole
application, plus a number of UNIX utilities I often use, in one single day.
I was extremely pleased with the product, never had any major complaint except
for optimization (which is now fixed in the latest release, see Kirk's advert.)
I would like to state that I am a physicist, I do mess around with computers
a lot, but I have no deep knowledge about soft/hardware, but I was able to
do everything I wanted and even more (this is basically "porting" the compiler
to my Sun workstation to generate assembly listing of the most crtitical
routine and hand optimize it a little).

I use Turbo C-s 'make' utility with this C compiler, I have my own (very good)
random number generator in the runtime library, that produces *exactly* the
same numbers as on UNIX, etc.

I have not seen the new optimizer yet, but would like to. My MOnte Carlo
simulation (totally in integer) ran about at 75% of the SUN 3/50, on one
processor. I somehow feel that one could do better than that. If it gives
a significant improvement, I think this product is a steal. Check it out.

- Cheers, Joseph,		joseph@chromo.ucsc.edu,

PS: I write this as a service to the newsgroup, not to Logical Systems.
    I beleive this is what is missing from the Transputer discussion,
    people should share their experience! I would have loved a contribution
    like this four months ago.
