[ydl-gen] Terra Soft Unifies Power Ecosystem with YDL v5.0.2:Announcement 14 June 2007

[Kai]

I'm not sure, but I think the two you are talking about are not SPUs,
these are the virtual cores of the PPE. I read that the PPE has a
virtual dual core like Intels hyperthreading. I suppose that the system
monitor isn't specialised for the CELL CPU and does not know about the SPUs.

If you boot your YDL you see 6 icons below the two YDL logos. IMHO the 2
dogs represent the two virtual cores of the CELLs PPE and the icons
represent the 6 SPE/SPUs. This makes me think you can use the SPUs in
your programs to optimize them to improve their performance.

There must be a pseudo filesystem mounted to access the SPUs have a look
at your "/".
