Btw GPU has its own cache and all problems related to it. You still have to watch what/how you do things on GPU to be cache friendly

- m_mueller 7y agoYes, but it's much less emphasized on GPU I think. If you have a data parallel algorithm, as long as you design the array ordering to allow coalesced access, the memory architecture will usually already allow better performance than what you can hope to get from CPU even with heavily cache optimized code that's basically unmaintainable (as it will likely perform much differently on the next architecture).
