151 Balasubramonian, RajeevLeveraging wire properties at the microarchitecture levelIn future microprocessors, communication will emerge as a major bottleneck. The authors advocate composing future interconnects of some wires that minimize latency, some that maximize bandwidth, and some that minimize power. A microarchitecture aware of these wire characteristics can steer on-chip ...Microarchitecture; Interconnects; Cache coherence2006-11

154 Reconstruction of sculptured surface using coordinate measuring machinesThis paper presents a strategy for reverse engineering that uses a coordinate measur ing machine to reconstruct three dimensional sculptured surfaces. A rough initial model of the surface is generated manually. An iterative method is then used to refine the surface model until the error is within a ...Reconstruction; Sculptured surface; Coordinate measuring machines1993
155 Riloff, Ellen M.Toward completeness in concept extraction and classificationMany algorithms extract terms from text together with some kind of taxonomic classification (is-a) link.

157 Zhang, LixinDesign a DRAM backend for the impulse memory systemThe Impulse Adaptable Memory System is a new memory system that exposes DRAM access patterns not seen in conventional memory systems. Impulse can generate huge number of small DRAM accesses, which will not be handled effectively by a conventional cache-line-size-access-oriented DRAM backend. In this...DRAM; Backend; Impulse memory system; Impulse Adaptable Memory System; Access patterns2000

160 Brunvand, Erik L.; Carter, JohnImpulse: building a smarter memory controllerImpulse is a new memory system architecture that adds two important features to a traditional memory controller. First, Impulse supports application-specific optimizations through configurable physical address remapping. By remapping physical addresses, applications control how their data is ac...1999
161 Shirley, Peter S.; Parker, Steven G.Towards interactive global illumination effects via sequential Monte Carlo adaptationThis paper presents a novel method that effectively combines both control variates and importance sampling in a sequential Monte Carlo context while handling general single-bounce global illumination effects.

162 Swope, Steven M.Simon II kernel reference manualThe principal objective of Simon II is to provide a flexible and adaptable framework for constructing simulators for a wide variety of parallel systems. A simulator consists of a set of software building blocks. Each building block, i.e. object, simulates a specific component of the parallel system...Simon II; Kernels; Simulators; Parallel systems1986
163 Balasubramonian, RajeevOptimizing communication and capacity in a 3D stacked reconfigurable cache hierarchyCache hierarchies in future many-core processors are expected to grow in size and contribute a large fraction of overall processor power and performance. In this paper, we postulate a 3D chip design that stacks SRAM and DRAM upon processing cores and employs OS-based page coloring to minimize hori...Multi-core processors; Cache and memory hierarchy; Non-uniform cache architecture (NUCA); Page coloring; On-chip networks; SRAM/DRAM cache reconfiguration2009-02
164 Thomas, Spencer W.Set operations on sculptured solidsA general method is presented for performing Boolean set operations on solids represented by a sculptured surface boundary model. The method is developed first for solids with closed boundary surfaces. It is then shown to apply also to "partially bounded" solids, which have incompletely specified b...Set operations; Sculptured solids; Sculptured surface; Boundary model1987
