Abstract
In one example, a central processing unit (CPU) with dynamic thread mapping includes a set of multiple cores each with a set of multiple threads. A set of registers for each of the multiple threads monitors for in-flight memory requests the number of loads from and stores to at least a first memory interface and a second memory interface by each respective thread. The second memory interface has a greater latency than the first memory interface. The CPU further has logic to map and migrate each thread to respective CPU cores where the number of cores accessing only one of the at least first and second memory interfaces is maximized.
