Ok, if I want to start experimenting with a transputer based computer system, what can I go out and buy NOW? I would like a system with some graphics capability and a halfway decent C and/or Occam compiler. It should also have the ability to expand to several (4-5) transputer cpu's without a lot of trouble. What kind of system could I get now and how much would it cost me? The only computer I have right now to use with it would be a Mac+ although a Mac II is possible. All in all I would rather have a completely stand-alone transputer system though. Cost is important!

Has anyone out there done a table of comparison between the various micro chips available and their cost/chip, cost/mip, cost/mflop? How does the T800 compare with the M68030 or MIPS chips. This should lead to lots of debate on what is a mip wrt Occam ( risc??) and more traditional languages.

Well, Inmos mentioned Whetstones in the Electronics article, announcing it as having the fastest floating-point unit. I don't have the figures in front of me for the T800, but the MIPS R2000/R2010 gets 12 MegaWhetstones single precision, and 9.3 MegaWhetstones double precision when run at 16.67 MHz, which was about double the figure for T800. We'd rate a 16.67 MHz system with full size (64kbyte each) caches and reasonably fast, local, memory at 12 MIPS (or 12 times faster than a VAX-11/780). It appears the the T800 performance Whetstone figure has code and data running out of the internal memory, and that the same figure with off-chip memory and/or caches will be slower. - anyone have details? Cost? MIPS quotes 5000 quantity prices of $195 for the R2000 CPU and $295 for R2010 FPC. The price of the CPU is less than the 5000 quantity price for a '386. > This should lead to lots of debate on what is a mip wrt Occam ( risc??) > and more traditional languages. Not from me. I'd bet Occam disappears as fast as you can get C compilers for the Transputer. Incidentally, does anyone know whether the the T800 Whetstone figure was from an honest-to-golly Fortran compiler, or did they "hand-code" the benchmark? -- Craig Hansen Manager, Architecture Development MIPS Computer Systems, Inc. ...decwrl!mips!hansen
