That information isn't really accurate. I attended the Cell "Hack-a-thon" back in February. It was a week-long workshop to learn Cell programming. Michael McCool and I spent a few days incorporating his RapidMind toolkit into Mesa's fragment program interpreter. At the end of the week we had enough working that the 'fslight' demo ran about 7 times faster (than just running on the PPC core) but it was still pretty slow. Since a limited number of instructions were supported, that was the only demo that actually worked. We haven't done any more work since then. > As I am currently looking > for a diploma thesis topic dealing with the cell and porting software > to it, I would like to know how the status of this project is and if > there are work items left where you could need some support. The RapidMind toolkit isn't the right solution for a real OpenGL implementation on Cell, for various reasons. To get decent performance, more radical architectural changes will be needed. We (TG) are hoping to do some work in this area in the future. Is your thesis more concerned with "just porting" to Cell, or writing highly-tuned Cell software? My impression is that getting the best performance out the Cell processor often involves re-architecting software from the bottom up. -Brian ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
