—Modern and emerging data centers are presenting unprecedented demands in terms of cost and energy consumption , far outpacing architectural advances related to economies of scale. Consequently, blade designs exhibit significant cost and power inefficiencies, particularly in the memory system. For example , we observe that modern blades are often… (More)
The Networked Digital Library of Theses and Dissertations (NDLTD) is a collaborative effort of universities around the world to promote creating, archiving, distributing and accessing Electronic Theses and Dissertations (ETDs). Since its inception in 1996, over a hundred universities have joined the initiative, underscoring the importance institutions place… (More)
—A novel ring-resonator-based integrated photonic chip with ultrafine frequency resolution, providing program-mable, stable, and accurate optical-phase control is demonstrated. The ability to manipulate the optical phase of the individual frequency components of a signal is a powerful tool for optical communications , signal processing, and RF photonics… (More)
SRW/U (the Search/Retrieve Webservice) and OAI (Open Archives Initiative) are both modern information retrieval protocols developed by distinct groups from different backgrounds at around the same time. This article sets out to briefly contrast the two protocols' aims and approaches, and then to look at some novel ways in which they have been or may be… (More)
On-line and off-line analysis Retail analysis Forecasting Pricing Etc… Combination of relational data queries and computational kernels Current applications process 1 to 50 TBs of data  Not a traditional domain for GPU acceleration, but: Parallel queries experience good speedup on GPUs  GPU-related techniques can be applied to other " Big… (More)
Our new fingerspelling practice software displays realistic animations of fingerspelling, including naturalistic transitions between letters that were previously impossible.
Future data center configurations are driven by total cost of ownership (TCO) for specific performance capabilities. Low-latency interconnects are central to performance , while the use of commodity interconnects is central to cost. This paper reports on an effort to combine a very high-performance, commodity interconnect (HyperTransport) with a high-volume… (More)
Traditionally, data warehousing workloads have been processed using CPU-focused clusters, such as those that make up the bulk of available machines in Amazon's EC2, and the focus on improving analytics performance has been to utilize a homogenous, multi-threaded CPU environment with optimized algorithms for this infrastructure. The increasing… (More)
