Intel Labs Invests $30M in the Future of Cloud and Embedded Computing with the Opening of Latest Intel Science and Technology Centers

SANTA CLARA, Calif., August 3, 2011 – Aimed at shaping the future of cloud computing and how increasing numbers of everyday devices will add computing capabilities, Intel Labs announced the latest Intel Science and Technology Centers (ISTC) for Cloud Computing Research and for Embedded Computing, both headquartered at Carnegie Mellon University.

The ISTC for Cloud Computing forms a new cloud computing research community that broadens Intel's "Cloud 2015" vision with new ideas from top academic researchers, and includes research that extends and improves on Intel's existing cloud computing initiatives. The center combines top researchers from Carnegie Mellon University, Georgia Institute of Technology, University of California Berkeley, Princeton University, and Intel. The researchers will explore technology that will have has important future implications for the cloud, including built-in application optimization, more efficient and effective support of big data analytics on massive amounts of online data, and making the cloud more distributed and localized by extending cloud capabilities to the network edge and even to client devices.

In the future, these capabilities could enable a digital personal handler via a device wired into your glasses that sees what you see, to constantly pull data from the cloud and whisper information to you during the day -- telling you who people are, where to buy an item you just saw, or how to adjust your plans when something new comes up.

Three Mutlu Papers Named Top Picks

Three research papers co-authored by Assistant Professor of ECE Onur Mutlu have been published in a collection of 2010's most significant computer architecture papers, as chosen by IEEE Micro magazine. At the beginning of each year, the leading IEEE periodical in computer architecture and design selects 10–12 "Top Pick" computer architecture papers of the past year based on the publication's novelty and potential for long-term impact. Eleven were selected for 2010.

The first publication, "Aergia: Exploiting Packet Latency Slack in On-Chip Networks," highlights more efficient on-chip communication mechanisms. It introduces methods that identify messages critical for system performance in multicore systems and develops scheduling policies that take advantage of this information. The paper — co-written by Mutlu, Reetuparna Das (Intel), Chita Das (Penn State University), and Thomas Moscibroda (Microsoft Research) — originally appeared at the 37th International Symposium on Computer Architecture (ISCA). The Top Picks version of the paper is available here.

In the second Top Pick, "Data Marshaling for Multicore Architectures," Mutlu and colleagues from the HPS Research Group at the University of Texas at Austin develop hardware/software cooperative methods to reduce the performance overhead of remotely executing a code segment in a multicore system. The paper, co-written by Aater Suleman, Jose Joao, Khubaib, and Yale Patt, also originally appeared at the 37th ISCA. The Top Picks version of the paper is available here.

The third paper, "Thread Cluster Memory Scheduling: Exploiting Differences in Memory Access Behavior," presents a new memory scheduling algorithm that addresses system throughput and fairness separately with the goal of achieving the best of both. This paper, co-authored by Yoongu Kim, Michael Papamichael and Mor Harchol-Balter, appeared in the Proceedings of the 43rd International Symposium on Microarchitecture (MICRO), pages 65-76, Atlanta, GA, December 2010.
