32.4: An Electronic Ink Low Latency Drawing Tablet

Abstract: Using an electronic ink display and a touchpanel input device, a paper-like drawing tablet was created, closely mimicking the behaviour of normal paper. The tablet is initially intended to serve as an input-device for cartoon drawing and editing. However, its potential use goes far beyond that.

Thin client intelligent transportation system and method for use therein

Abstract: A thin client intelligent transportation system wherein geospatial roadmaps and map matching systems are maintained in roadside nodes and are more fully exploited. The thin client approach offers significant advantages over thick client approaches that rely on on-vehicle maps and map matching systems, including reduced complexity of on-board equipment and elimination of map integrity issues. The thin client approach also offers significant advantages over systems wherein the vehicle is required to access maps and map matching systems in real-time from a remote data center, including the ability to meet the low latency requirements for many vehicle safety applications. The present invention in some embodiments has added advantages in that it exploits roadside maps and map matching systems in revenue generating applications that are not directly related to passenger safety.

Zoolander: Efficiently Meeting Very Strict, Low-Latency SLOs.

Abstract: Internet services access networked storage many times while processing a request. Just a few slow storage accesses per request can raise response times a lot, making the whole service less usable and hurting profits. This paper presents Zoolander, a key value store that meets strict, low latency service level objectives (SLOs). Zoolander scales out using replication for predictability, an old but seldom-used approach that uses redundant accesses to mask outlier response times. Zoolander also scales out using traditional replication and partitioning. It uses an analytic model to efficiently combine these competing approaches based on systems data and workload conditions. For example, when workloads under utilize system resources, Zoolander’s model often suggests replication for predictability, strengthening service levels by reducing outlier response times. When workloads use system resources heavily, causing large queuing delays, Zoolander’s model suggests scaling out via traditional approaches. We used a diurnal trace to test Zoolander at scale (up to 40M accesses per hour). Zoolander reduced SLO violations by 32%.

Highly scalable network on chip for reconfigurable systems

Abstract: An efficient methodology for building the billion-transistors systems on chip of tomorrow is a necessity. Networks on chip promise to be the solution for the numerous technological, economical and productivity problems. We believe that different types of networks are required for each application domains. Our approach therefore is to have a very flexible network design, highly scalable, that allows to easily accommodate the various needs. This paper presents the design of our network on chip, which is part of the platform we are developing for reconfigurable systems. The present design allows us to instantiate arbitrary network topologies, has a low latency and high throughput.
