Due to the increasing complexity of multi/manycore architectures (with their mix of caches and scratch-pad memories) and applications (with different memory access patterns), the performance of many workloads becomes increasingly variable. In this paper, the authors address one of the main causes for this performance variability: the efficiency of the memory system. Specifically, based on an empirical evaluation driven by memory access patterns, they qualify and partially quantify the performance impact of using local memory in multi/many-core processors.
