One of the techniques they use to solve the memory bandwidth problem is to have four memory controllers.
- lallysingh 18y agoYeah, but the way it does it is by switching concurrent threads when the last gets stalled on memory. It's brilliant, and seems effective, but it's still just 8 cores per socket.
- Retric 18y agoThis is useful to get around the latency issues, which let's you use more of your memory bandwidth before stalling a core.
