The superior I/O performance of solid-state storage (e.g., solid-state drives) makes it become an attractive replacement for the traditional magnetic storage (e.g., harddisk drives). More and more storage systems start to integrate solid-state storage into their architecture. To understand the impacts of solid-state storage on the performance of Hadoop applications, we consider a hybrid Hadoop storage...
Parallel computing is an important method used in high performance computing. A new SIMD architecture named ESCA (Engineering and Science Computing Accelerator) is introduced briefly in this paper. It aims to accelerate the computation for most critical scientific workload as a coprocessor by virtue of outstanding architecture and flexible parallel algorithm. As dense matrix multiplication is a widely...
The α-β algorithm is an efficient technique for searching game trees. In this paper, we present the detailed implementation of parallel α-β algorithm on our Engineering and Scientific Computation Accelerator (ESCA) system, which is a heterogeneous multi-core SIMD (Single Instruction stream Multiple Data stream) architecture to accelerate the compute-intensive parallel computing in high performance...
Extensive research has been done for efficient computation of probabilistic queries posed to Bayesian networks (BNs). One popular architecture for exact inference on BNs is the Junction Tree (JT) based architecture. Among all variations developed, HUGIN is the most efficient JT-based architecture. The Global Propagation (GP) method used in the HUGIN architecture is arguably one of the best methods...
In this paper, we propose an improved architecture that supports exact MSBN belief updating using iterative message passing. Compared with recursive inference algorithms, iterative message passing is more robust in a multiagent environment where agents often have to face unreliable communication channels. Our method improves the overall time efficiency of existing iterative methods by avoiding repeated...
Recent years, it has been a hot research topic on providing efficient and unbounded transactional memory support through hybrid hardware and software approach. Yet, current proposed systems which buffer transactional data in traditional data cache have high overhead and design complexity. In this paper, we propose a new design approach to build hybrid transactional memory system. Our approach adds...
Transactional memory (TM) provides efficient, easy, deadlock-free parallel programming model for today's multicore-ubiquitous hardware platform. Implementation of TM needs to guarantee that the transaction is executed atomically and in isolation. Our paper proposes an efficient and unbounded hybrid-mode TM system with strong isolation guarantee, called HybridTCache. HybridTCache optimizes the common...
UDDI acts a very important role in the web service. It can be used to publish and lookup services. Most of the current UDDI models are centralized so that the performance will decrease if there are too many services to be registered or queried. In this paper, an interoperable model of distributed UDDI is proposed. The model divides whole UDDI servers into there types: root server, super domain server...
