Jenga: Harnessing Heterogeneous Memories through Reconfigurable Cache Hierarchies

Jenga: Harnessing Heterogeneous Memories through Reconfigurable Cache Hierarchies Beckmann, Nathan; Tsai, Po-An; Sanchez, Daniel Conventional memory systems are organized as a rigid hierarchy, with multiple levels of progressively larger and slower memories. Hierarchy allows a simple, fixed design to benefit a wide range of applications, because working sets settle at the smallest (and fastest) level they fit in. However, rigid hierarchies also cause significant overheads, because each level adds latency and energy even when it does not capture the working set. In emerging systems with heterogeneous memory technologies such as stacked DRAM, these overheads often limit performance and efficiency. We propose Jenga, a reconfigurable cache hierarchy that avoids these pathologies and approaches the performance of a hierarchy optimized for each application. Jenga monitors application behavior and dynamically builds virtual cache hierarchies out of heterogeneous, distributed cache banks. Jenga uses simple hardware support and a novel software runtime to configure virtual cache hierarchies. On a 36-core CMP with a 1 GB stacked-DRAM cache, Jenga outperforms a combination of state-of-the-art techniques by 10% on average and by up to 36%, and does so while saving energy, improving system-wide energy-delay product by 29% on average and by up to 96%.

Bridging Theory and Practice in Cache Replacement

Bridging Theory and Practice in Cache Replacement Beckmann, Nathan; Sanchez, Daniel Much prior work has studied processor cache replacement policies, but a large gap remains between theory and practice. The optimal policy (MIN) requires unobtainable knowledge of the future, and prior theoretically-grounded policies use reference models that do not match real programs. Meanwhile, practical policies are designed empirically. Lacking a strong theoretical foundation, they do not make the best use of the information available to them. This paper bridges theory and practice. We propose that practical policies should replace lines based on their economic value added (EVA), the difference of their expected hits from the average. We use Markov decision processes to show that EVA is optimal under some reasonable simplifications. We present an inexpensive, practical implementation of EVA and evaluate it exhaustively over many cache sizes. EVA outperforms prior practical policies and saves area at iso-performance. These results show that formalizing cache replacement yields practical benefits.

Cache Calculus: Modeling Caches through Differential Equations

Cache Calculus: Modeling Caches through Differential Equations Beckmann, Nathan; Sanchez, Daniel Caches are critical to performance, yet their behavior is hard to understand and model. In particular, prior work does not provide closed-form solutions of cache performance, i.e. simple expressions for the miss rate of a specific access pattern. Existing cache models instead use numerical methods that, unlike closed-form solutions, are computationally expensive and yield limited insight. We present cache calculus, a technique that models cache behavior as a system of ordinary differential equations, letting standard calculus techniques find simple and accurate solutions of cache performance for common access patterns.

Tools for Life: Exploring Assistive Technology Strategies & Solutions

Tools for Life: Exploring Assistive Technology Strategies & Solutions Persaud, Elizabeth; Phillips, Carolyn P.; Wilson, Rachel The world around us is evolving at an astounding rate. Assistive Technology developments have been foundational in this evolution and a catalyst for producing positive life-changing results for individuals with disabilities, especially as we age. This talk will present what’s new in AT and the Aging in Place movement as we explore where we were, where we are, and perhaps, where we are going. During the session presenters will share information about low, middle and high tech assistive technologies. Discussion will focus on tracking technological trends including apps, mobile devices, robotics, wearable technologies and more. Apps to assist with aging well will be shown and resources for tracking trends will be shared. There are many obstacles older individuals encounter daily that can hinder them from remaining at home and in the communities of their choice. Join us for an insightful session that will shed some light on assistive technology strategies, solutions and devices that are used to help individuals age successfully in communities of their choice. Presenters will share real-life examples of AT that assists with fall detection and prevention, environmental control, memory, healthy-living, hearing, seeing, communication, and computer access. Presented on December 15, 2015 from 9:30 - 10:30 am in Room 207 of the Health Systems Institute (HSI) Building.; Liz Persaud is a nationally recognized keynote and public speaker addressing the need to build bridges between individuals with and without disabilities. Liz currently serves as the Training, Outreach and Development Coordinator for Tools for Life (Georgia’s Assistive Technology Act Program) and the Pass It On Center (National Assistive Technology Device Reutilization Coordination and Technical Assistance Center).; Carolyn P. Phillips is nationally recognized in the field of assistive technology and disabilities. Carolyn serves as Director and Principal Investigator of Tools for Life, Georgia’s Assistive Technology (AT) Act Program at Georgia Tech | AMAC. In this capacity, she oversees a wide range of AT projects and programs, including the National Pass It On Center.; Rachel Wilson is a Certified Occupational Therapy Assistant (COTA) who has been practicing for over 23 years. She specializes in Rehabilitation and has a strong background in Transition and Aging. She has worked with numerous individuals with disabilities to transition back to their home or highest level of independence in the most appropriate environment. Her interests include assistive technology, advocacy, self-determination and functional independence so individuals can live, learn, work and play in communities of their choice.; Runtime: 61:36 minutes
