Title ABP : predictor based management of DRAM row buffers
Date 2010-10-06
Description DRAM accesses are costly, especially in multicore systems. Future CMPs will run a mixed load of workloads/threads. Destructive interference at memory controller, spatio-temporal locality lost! DRAM row-buffer hits are least expensive, row-conflicts are most. Randomized memory access patterns render traditional row-buffer management policies useless. Most commercial CMPs have no buffer management policies implemented [1]. Timer based policies [2,3] are too coarse-grained to be effective. Rather then time, focus on access patterns. Access patterns are predictable, a predictor can accurately predict the number of accesses for which the row-buffer be kept open. In any case, can't do worse than a static policy.
