  • Many-core parallel computing - Can compilers and tools do the heavy lifting?

    Publication Year: 2009, Page(s): 1
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (36 KB) | HTML iconHTML

    Modern GPUs such as the NVIDIA GeForce GTX280, ATI Radeon 4860, and the upcoming Intel Larrabee are massively parallel, many-core processors. Today, application developers for these many-core chips are reporting 10X-100X speedup over sequential code on traditional microprocessors. According to the semiconductor industry roadmap, these processors could scale up to over 1,000X speedup over single co... View full abstract»

  • Software transactional memory: Where do we come from? What are we? Where are we going?

    Publication Year: 2009, Page(s): 1

    The transactional memory programming paradigm is gaining momentum as the approach of choice for replacing locks in concurrent programming. Combining sequences of concurrent operations into atomic transactions seems to promise a great reduction in the complexity of both programming and verification, by making parts of the code appear to be sequential without the need to program fine-grained locks. ...

    It is clear from both the cooling demands and the electricity costs, that the growth in scientific computing capabilities of the last few decades is not sustainable unless fundamentally new ideas are brought to bear. In this talk we propose a novel approach to supercomputing design that leverages the sophisticated tool chains of the consumer electronics marketplace. We analyze our framework in the...

    In order to work efficiently, clusters for high performance computing require a balance between the compute, memory, inter-node communication, and I/O. Fast communications among one thousand multicore nodes requires short wire paths and power-efficient CPUs tightly integrated with memory, communication, and I/O controllers. The tutorial describes the characteristics of a six thousand core cluster ... View full abstract»

    Over the last decade, commodity graphics processors (GPUs) have evolved from fixed-function graphics units into powerful, programmable data-parallel processors. Today's GPU is capable of sustaining computation rates substantially greater than today's modern CPUs, with technology trends indicating a widening gap in the future. Researchers in the rapidly evolving field of GPU computing have demonstr... View full abstract»

    The term resiliency has been used in many fields like child psychology, ecology, business, and several others, with the common meaning of expressing the ability to successfully accommodate unforeseen environmental perturbations or disturbances. The adjective resilient has been in use for decades in the field of dependable computing systems however essentially as a synonym of fault-to... View full abstract»

    In this talk I will describe recent work to develop novel methods to model G protein-coupled receptor (GPCR) structures from their sequence information and statistically significant side chain contacts within a ldquotemplaterdquo structure. Our approach utilizes methods of bioinformatics to identify likely high confidence side chain side chain TM helical contacts and then reconstitutes the seven T... View full abstract»

  • Crosstalk-free mapping of two-dimensional weak tori on optical slab waveguides

    Publication Year: 2009, Page(s):1 - 8
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (144 KB) | HTML iconHTML

    While optical slab waveguides can deliver a huge bandwidth for the communication need through offering a huge number of communication channels, they require a large number of high speed lasers and photodetectors. This makes a limited use of the offered huge bandwidth. Some trials were proposed to implement communication networks on the slab waveguides [7]. However, the proposed mappings suffer fro...

  • Table-based method for reconfigurable function evaluation

    Publication Year: 2009, Page(s):1 - 9
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1105 KB) | HTML iconHTML

    This paper presents a new approach to function evaluation using tables. The proposal argues for the use of a more complete primitive, namely a weighted sum, which converts the calculation of the function values into a recursive operation defined by a two input table. This weighted sum can be tuned for different values of the weighting parameters holding the features of the specific function to be ... View full abstract»

    We consider the uniform scattering problem for a set of autonomous mobile robots deployed in a grid network: starting from an arbitrary placement in the grid, using purely localized computations, the robots must move so to reach in finite time a state of static equilibrium in which they cover uniformly the grid. The theoretical quest is on determining the minimal capabilities needed by the robots ... View full abstract»
