The 3rd International Workshop of Software-Defined Data Communications and Storage (SDDCS) 2017, in conjunction with ACM ASPLOS 2017, on April 8, 2017, in Xi'an, China.
Keynote Speech: Memory-Centric Architectures to Close the Gap Between Computing and Memory/Storage
Yuan Xie, University of California at Santa Barbara
Abstract: Traditional computer systems usually follow the so-called classic Von Neumann architecture, with separated processing units (such as CPUs and GPUs) to do computing and separated memory units for data storage. The increasing gap between the computing of processor and the memory has created the “memory wall” problem in which the data movement between the processing units (PUs) and the data storage is becoming the bottleneck of the entire computing system, ranging from cloud servers to end-user devices. As we enter the era of big data, many emerging data-intensive workloads become pervasive and mandate very high bandwidth and heavy data movement between the computing units and the memory/storage. This talk will discuss the design opportunities and challenges for memory-centric architecture, which is proposed to close the gap between computing and data storage, with the emerging data-intensive applications such as neural computing and graph analytics as application drivers to guide the architecture optimization.
Bio: Yuan Xie is a professor at UC Santa Barbara (UCSB). He received Ph.D. from Princeton University, and then joined IBM Microelectronics as advisory engineer. From 2003 to 2014 he was with Penn State as Assistant/Associate/Full professor. He also worked with AMD research between 2012-2013. His research interests include EDA/architecture/VLSI, and has published more than 200 papers in IEEE/ACM venues.

Please indicate that this is an extended version from SDDCS 2017 workshop submission in the cover letter to facilitate identification.
Making an infrastructure “software defined” takes cross community efforts. Just like the theme of ASPLOS that brings together the architecture, systems and programming language community, SDDCS provides a multi-disciplinary forum for system research, spanning from storage devices, software systems, network virtualization and applications, focusing on the important problem of making future systems software-defined.
The future infrastructures of the data centers and cloud computing are becoming increasingly software-defined. Although the infrastructures consist of communications and storage resources, they are generally studied separately. Hence, applications and platforms have to precisely define the virtual environment in which they wish to run. The communication performance decreases due to overlooking the properties of storage devices, and vice versa. Software-defined methodologies offer an opportunity to bridge their gap and deliver high performance.
The SDDCS workshop provides the forum for multi-disciplinary research spanning data communications, networking, storage systems and devices, as well as the applications. SDDCS aims to bring together industry and academia to jointly explore recent progresses related to the potential performance bottleneck and the gap between communications and storage in the software-defined context. We particularly encourage contributions containing highly novel ideas, new approaches, and/or groundbreaking results.
Topics of interests in SDDCS include but are not limited to:
Software-defined memory system for cloud computing
Software-defined non-volatile devices
Convergent design for communications and storage
Non-volatile storage support for network transmission
Storage deduplication for remote cloud backups
Data collection and analytics for system optimization
Dynamic workload redistribution and scheduling
Non-volatile devices in network switches
Cross-layer coordination in data centers
Storage virtualization in data centers
Security for SDDCS schemes
Programmable interfaces for convergent design
