Games PC Linux distributor Terra Soft has announced plans to release its Yellow Dog Linux distribution for Sony's upcoming PlayStation 3 gaming console. Featuring the experimental e17 desktop environment, Terra Soft's upcoming distribution release is surprisingly unconventional. Ars talked to Terra Soft CEO Kai Staats and Enlightenment developer Carsten 'Rasterman' Haitzler about Linux and the PS3.

I'd have to agree with this in many repsects. Although I do hope that the hardware will be available, an optimized (and ideally dynamically-compiled) software rendering implimentation could do quite well on the Cell CPU. Of the 7 SPEs available, reserving 2 for geometry (vertex) processing, 4 for pixel processing, and leaving the last to other tasks could yield good results. Certainly not top-of-the-line, but I would estimate something akin to a radeon 9600 or Geforce 4 level of capability. Originally, Sony had hoped that that a multi-cell system would be capable of handling graphics -- which would have likely been true if things had continued at the pace they were 5 years ago, but there was an explosion in graphics power brought about by nVidea and particularly ATI.

Graphics is one of the few tasks that the SPEs *really* excel at. It's not branchy, it's spacialy localized, it lends itself to DMA and it's embarressingly parallel... Depending on the color depth you want to support you could get 4, 8 or even 16 "pixel pipelines" out of 4 SPEs (128bit/HDR, 64bit/half-HDR or 32bit respectively, assuming that the SPEs support integer and half-floats.)

Can you tell that software rendering is a bit of a hobby for me? ;)
