In this paper, we study parallel I/O efficient graph algorithms in the Parallel External Memory (PEM) model, one o f the private-cache chip multiprocessor (CMP) models. We study the fundamental problem of list ranking which leads to efficient solutions to problems on trees, such as computing lowest common ancestors, tree contraction and expression tree evaluation. We also study the problems of computing...
Multi-comparand associative processors are efficient in parallel processing of complex search problems that arise from many application areas including computational geometry, graph theory and list/matrix computations. In this paper we report new FPGA implementations of a multi-comparand multi-search associative processor. The architecture of the processor working in a combined bit-serial/bit-parallel...
Modern microprocessors are becoming increasingly parallel devices, and GPUs are at the leading edge of this trend. Designing parallel algorithms for manycore chips like the GPU can present interesting challenges, particularly for computations on sparse data structures. One particularly common example is the collection of sparse matrix solvers and combinatorial graph algorithms that form the core of...
