cell in order - so what ?

On cell developers will have compiler optimizations like autovectorisation and other ...


http://gcc.gnu.org/projects/tree-ssa/vectorization.html



I think it's easier for me to think cell


as mini cluster


powerpc as master (conductor) and spu's as slaves (orchestra) with crunching jobs submited to them


Vectorial code (simd) aka symphony is arranged by compiler (composer) at another time


Don't forget that memory is closer to cpu (integrated controller) and doesn't need to much of cache and OOo prediction for brached code (low latency)
