Based on the observation that there are many cold pages in data-center applications, \u0000<italic>proactive demotion</i>\u0000 schemes demote cold pages to slow memory even when free space in fast memory is not deficient. Prior works on proactive demotion lower the requirement of expensive fast-memory capacity by reducing applications’ resident set size in fast memory. Also, some of the prior works mitigate the massive performance drop due to insufficient fast-memory capacity when there is a spike in demand for hot data. However, there is room for further improvement to save a larger fast-memory capacity with further aggressive demotion, which can fully reap the aforementioned advantages of proactive demotion. In this paper, we propose a new proactive demotion scheme, ADT, which performs \u0000<bold>a</b>\u0000ggressive \u0000<bold>d</b>\u0000emotion and promotion for \u0000<bold>t</b>\u0000iered memory. Using the memory access locality within the unit in which applications and memory allocators allocate memory, ADT extends the unit of demotion/promotion from the page adopted by prior works to make its demotion more aggressive. By performing demotion and promotion by the extended unit, ADT reduces 29% of fast-memory usage with only a 2.3% performance drop. Also, it achieves 2.28× speedup compared to the default Linux kernel when the system's memory usage is larger than fast-memory capacity, which outperforms state-of-the-art schemes for tiered memory management.","PeriodicalId":51248,"journal":{"name":"IEEE Computer Architecture Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43125075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of these modern NLP models adopt the Transformer based model architecture, whose main bottleneck is exhibited in the self-attention mechanism. As the computation required for self-attention increases rapidly as the model size gets larger, self-attentions have been the main challenge for deploying NLP models. Consequently, there are several prior works which sought to address this bottleneck, but most of them suffer from significant design overheads and additional training requirements. In this work, we propose HAMMER, hardware-friendly approximate computing solution for self-attentions employing mean-redistribution and linearization, which effectively increases the performance of self-attention mechanism with low overheads.

However, prior studies focus on the core allocation for application threads while not considering cores involved in network packet processing, even though packet processing affects not only response latency but also energy consumption considerably. In this paper, we first investigate the impacts of the explicit core allocation for network packet processing on the tail response latency and energy consumption while running LC applications. We observe that co-adjusting the number of cores for network packet processing along with the number of cores for LC application threads can improve energy efficiency substantially, compared with adjusting the number of cores only for application threads, as prior studies do. In addition, we propose a dynamic core allocation, called \u0000<monospace>CoreNap</monospace>\u0000, which allocates/de-allocates cores for both LC application threads and packet processing. \u0000<monospace>CoreNap</monospace>\u0000 measures the CPU-utilization by application threads and packet processing individually, and predicts response latency and power consumption when the combination of core allocation is enforced via a lightweight prediction model. Based on the prediction, \u0000<monospace>CoreNap</monospace>\u0000 chooses/enforces the energy-efficient combination of core allocation. Our experimental results show that \u0000<monospace>CoreNap</monospace>\u0000 reduces energy consumption by up to 18.6% compared with state-of-the-art study that adjusts cores only for LC application in parallel packet processing environments.","PeriodicalId":51248,"journal":{"name":"IEEE Computer Architecture Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42616181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
