Since the introduction of the stable marriage problem (SMP) by Gale and Shapley (1962), several variants and extensions have been investigated. While this variety is useful to widen the application potential, each variant requires a new algorithm for finding the stable matchings. To address this issue, we propose an encoding of the SMP using answer set programming (ASP), which can straightforwa...

We evaluate performance on NAS benchmarks of a cluster of 2-way SMP PCs connected by a Myrinet network. Two programming models are considered. A Single Memory Model uses the MPI-BIP/CLUMP library and gives the programmer a uniied memory view. A Hybrid Memory Model combines shared memory model within nodes and message passing between nodes. We compare 2-way SMP conngurations speed-up versus sing...

Throughout the years, as Unix has grown and evolved so has computer hardware. The 4.4BSD-Lite2 distribution had no support for two features that are becoming more and more important: SMP and real-time processing. With the release Mac OS X Apple has made extensive alterations to our kernel in order to support both SMP and real-time processing. These alterations affected both the BSD and Mach por...

This paper presents an hour-ahead System Marginal Price (SMP) forecasting framework based on a neural network. Recently, the deregulation in power industries has impacted on the power system operational problems. The bidding strategies in energy market among market participants are highly dependent on the short-term price levels. Therefore, short-term SMP forecasting is a very important issue t...

OpenMP ooers a high-level interface for parallel programming on scalable shared memory (SMP) architectures providing the user with simple work-sharing directives while relying on the compiler to generate parallel programs based on thread parallelism. However, the lack of language features for exploiting data locality often results in poor performance since the non-uniform memory access times on...

The trend towards producing workstations, which have multiprocessors (SMPs), increases research endeavors to build cheaper but powerful parallel programming platforms through connecting such workstations. Besides building such platforms, providing mechanisms, layers of abstraction, or libraries to enable programmers to gain the power of SMP clusters is another challenging field of research. Vie...

The three-level hybrid parallel programming model consisting of MPI, OpenMP and vectorization with multicolor-based reordering methods provides optimum performance on SMP cluster architectures with vector processors such as the Earth Simulator (ES) for finite-element type applications. While the three-level hybrid and flat MPI parallel programming models offer similar performance, the hybrid pr...

We explore the current capabilities of the recently released Myricom X2OOO witch, using MPICH over the GM communication layer; for message passing on a 2-way SMP Pentium III Beawulf-Class cluster: Performance measurements on the network indicate that data transfer rates of appmximatety 190 Mbyteds for ping-pong tests, and 24OMbyteds forfill-duplex exchange tests, can be achieved for messages as...

This paper proposes a novel approach for the parallel execution of tiled Iteration Spaces onto a cluster of SMP PC nodes. Each SMP node has multiple CPUs and a single memory mapped PCI-SCI Network Interface Card. We apply a hyperplane-based grouping transformation to the tiled space, so as to group together independent neighboring tiles and assign them to the same SMP node. In this way, intrano...

The field data collected as part of the international Joint Global Ocean Flux Study (JGOFS) provide an unprecedented view of marine biogeochemistry and the ocean carbon cycle. Following the completion of a series of regional process studies, a global CO2 survey, and a decade of sampling at two open-ocean timeseries, US JGOFS initiated in 1997 a final research phase, the Synthesis and Modeling P...
