This you can think being data for single processor. Without optimizing, PPE just runs data to SPE:s without a single SPE being tasked to certain kind of data. Did i go wrong somewhere? |
No, the code for the PPE and SPEs are compiled separately. Kars is saying that the development approach is to program everything on the PPE, test it, work out all the bugs, then start "porting" the important bits of code to the SPEs to improve performance. It's much easier to find bugs when you're only running code on one core.
