Network science makes heavy use of simulation models and calculations based upon graph-oriented data structures that are intrinsically highly irregular in nature. The key to efficient use of data-parallel and multi-core parallelism on graphical processing units (GPUs) and CPUs is often to optimise the data layout and to exploit distributed memory locality with processing elements. We describe w...

The exploitation of locality of reference in shared memory multiprocessors is one of the most important problems in parallel processing today. Locality can be managed in several levels: hardware, operating system , runtime environment of the compiler, user level. In this paper we investigate the problem of exploiting locality at the operating system level and its interactions with the compiler ...

The goal of the Alewife experiment is to demonstrate that a parallel computer system can be made both scalable and easily programmable. Scalability will be achieved through an architecture that allows the exploitation of locality. That is, for programs that display communication locality, scalable machines can o er proportionally better performance with more processing nodes. A program running ...

A distributed graph processing system that provides locality control, indexing, graph query, and parallel processing capabilities is presented. Keywords—graph, distributed, semantic, query, analytics

The ChucK programming language lacks straightforward mechanisms for extension beyond its built-in programming and processing facilities. Chugens address this issue by allowing programmers to implement new unit generators in ChucK code in realtime. Chubgraphs also allow new unit generators to be built in ChucK, by defining specific arrangements of existing unit generators. ChuGins allow a wide a...

Internet server applications (such as web servers, ecommerce front-ends, etc) spend a significant portion of time processing network data. These applications use TCP/IP as the communication protocol which is known to be very memory intensive. In this paper, we present a simulation-based characterization of the cache/memory access behavior of TCP/IP processing in two popular commercial benchmark...

We have built and operated a tactile vision substitution system based on 48 piezoelectric actuators assembled in a movable tactile output unit. The unit can be positioned at any location on a two dimensional surface to explore the line structure of a virtual image. This virtual tactile display (VTD) receives data either from camera systems equipped with suitable image processing capabilities or...
