Energy-efficient cache partitioning for future CMPs
Karthik T. Sundararajan, Timothy M. Jones, Nigel P. Topham · 2012
The demand for high performance computing systems requires processor vendors to increase the number of cores per chip multiprocessor (CMP). However, as their number grows, the core-to-way ratio in the last level cache (LLC) increases, presenting problems to existing cache partitioning techniques which require more ways than cores. Further, effective energy management of the LLC becomes increasingly important due to its size.
