Box 1702 > Corvallis, OR 97339 > (503) 753-9051 > 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, reger@ucscc.bitnet. 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.
