There are a lot of performance benefits to managing the memory hierarchy yourself. But I think that the demise of the Cell demonstrated that not enough people are willing to do it to justify it as architectural decision.

- scott_s 14y agoI was talking about for a single chip. There was a lot of interest in Cell in the HPC market, but it also died. For applications that can tolerate the latency, offloading computation to the GPUs is such a multiplier in performance that they have to put up with manually managing the hierarchy - but even there, it's a rather coarse memory management.
