Re: Transputer Development System, 2006? (aka Sony PS/3 runs multi-core Linux)


We are also working on getting occam-pi running on the Cell. Unlike
Damians transterpreter our goal is to make the utilisation of the 8
spu cores totally transparent to the programmer (don't know if you
also have plans of this, Damian).

Our approach is to use the frontend of KRoC and then replace the
translator from transputer assembly to i386 assembly (tranx86) with a
translator that targets the Cell.

Indeed I am working on getting occam-pi running on the cell.  Aside from
yellow dog, I have read that redhats FC5 (with some cell specific bits)
is downloadable from sony.  Thanks for the pointer to the Yellow Dog
site, I am not the biggest redhat fan so when I do get around to it running
yellowdog could be a viable alternative!

I do agree though, the PS3 would be a great development system to have,
once they start selling it in Europe.  It definitely beats the overpriced
blade servers that IBM is selling....

If I remember correctly the versions of the cell shipped for the PS3
will have one or even two of the 'spu' vector processing cores disabled
in the
actual units in order to increase the yield when manufacturing the
processors.  Still 6 or 7 cores is still nice to play with.

I can't wait to get my hands on one.  For now it'll still just be the
cell system simulator.

Glad to hear people are interested though :).
