Title: | Lazypim: an Efficient Cache Coherence Mechanism for Processing-In | Authors: | Boroumand, Amirali Ghose, Saugata Patel, Minesh Hassan, Hasan Lucia, Brandon Hsieh, Kevin Mutlu, Onur |
Keywords: | [No Keywords] | Publisher: | IEEE Computer Soc | Abstract: | Processing-in-memory (PIM) architectures cannot use traditional approaches to cache coherence due to the high off-chip traffic consumed by coherence messages. We propose LazyPIM, a new hardware cache coherence mechanism designed specifically for PIM. LazyPIM uses a combination of speculative cache coherence and compressed coherence signatures to greatly reduce the overhead of keeping PIM coherent with the processor. We find that LazyPIM improves average performance across a range of PIM applications by 49.1 percent over the best prior approach, coming within 5.5 percent of an ideal PIM mechanism. | URI: | https://doi.org/10.1109/LCA.2016.2577557 https://hdl.handle.net/20.500.11851/6973 |
