    The many-core inflection point presents a new challenge for our industry, namely general-purpose parallel computing. Unless this challenge is met, the continued growth and importance of computing itself and of the businesses engaged in it are at risk. We must make parallel programming easier and more generally applicable than it is now, and build hardware and software that will execute arbitrary p... View full abstract»

    The next decades will see an explosion in the use and the scope of medical imaging, fueled by advanced computing and visualization techniques. In my opinion, advanced, multimodal imaging and visualization techniques, powered by new computational methods, will change the face of biology and medicine and provide comprehensive views of the human body in progressively greater depth and detail. As the ... View full abstract»

  • Keynote Speech: Avoiding the Memory Bottleneck through Structured Arrays

    Basic to parallel program speedup is dealing with memory bandwidth requirements. One solution is an architectural arrangement to stream data across multiple processing elements before storing the result in memory. This MISD type of configuration provides multiple operations per data item fetched from memory. One realization of this streamed approach uses FPGAs. We'll discuss both the general memor...

    Multi-cores are here to stay, whether we like it or not. With a quadrupling of the core count every three years, chips with hundreds of processor cores are projected in the next decade. The question is, how much of their computational power can be unleashed, what it will take to unleash it, and how best can research accelerate progress? Several decades of research in multiprocessing has not really... View full abstract»

    With the recent advent of 100s of teraFLOP/s-scale simulations capability at Lawrence Livermore National Laboratory and other sites, it has become clear that the scientific method has changed. This transition has taken us from theory and experiment to theory and experiment being tightly integrated by simulation. With the advent of peta-scale simulations on the horizon it is appropriate to take sto... View full abstract»

    Quantum physics is a fascinating area from a computational viewpoint. The features that make quantum systems prohibitively hard to simulate classically are precisely the aspects exploited by quantum computation to obtain exponential speedups over classical computers. In this talk I will survey our current understanding of the power (and limits) of quantum computers, and prospects for experimentall... View full abstract»

  • VoroNet: A scalable object network based on Voronoi tessellations

    In this paper, we propose the design of VoroNet, an object-based peer to peer overlay network relying on Voronoi tessellations, along with its theoretical analysis and experimental evaluation. VoroNet differs from previous overlay networks in that peers are application objects themselves and get identifiers reflecting the semantics of the application instead of relying on hashing functions.

  • Almost Peer-to-Peer Clock Synchronization

    In this paper, an almost peer-to-peer (AP2P) clock synchronization protocol is proposed. AP2P is almost peer-to-peer in the sense that it provides the desirable features of a purely hierarchical (client/server) clock synchronization protocol while avoiding the undesirable consequences of a purely peer-to-peer one. In AP2P, a unique node is elected as a leader in a distributed manner. Each non-lead... View full abstract»

    Replication and caching have been deployed widely in current P2P systems. In update-allowed P2P systems, a consistency maintenance mechanism is strongly demanded. Several solutions have been proposed to maintain the consistency of P2P systems. However, they either use too much redundant update messages, or ignore the heterogeneity nature of P2P systems. Moreover, they propagate updated contents on... View full abstract»

    In a recent study, we proposed a trusted gossip protocol for rumor resistant information sharing in peer-to-peer networks. While trust aware gossiping significantly reduced the rumor spread on the network, we observed that the random message spraying in trusted gossip creates too many redundant messages increasing the message overhead and error rate. In this paper, we propose a message targeting s... View full abstract»

    Bayesian phylogenetic inference is an important alternative to maximum likelihood-based phylogenetic method. However, inferring large trees using the Bayesian approach is computationally demanding - requiring huge amounts of memory and months of computational time. With a combination of novel parallel algorithms and latest system technology, terascale phylogenetic tools provide biologists the comp... View full abstract»

    In this paper, we describe how inverse space-filling curve partitioning is used to increase the simulation rate of a global ocean model. Space-filling curve partitioning allows for the elimination of load imbalance in the computational grid due to land points. Improved load balance combined with code modifications within the conjugate gradient solver significantly increase the simulation rate of t... View full abstract»
