parallel program design patterns provide users a new way to get parallel programs without much effort. However, it is always a serious limitation for most existing parallel pattern-based systems that there is no gener...

We use a parallel direct solver based on the Schur complement method for solving large sparse linear systems arising from the finite element method. A domain decomposition of a problem is performed using a graph parti...

the efficient execution of OLAP queries, which are typically readonly and heavy-weight, is a hard problem which has been traditionally solved using tightly-coupled multiprocessors. Considering a database cluster as a ...

A parallel extension to the Python language is introduced that is modeled after the Co-Array Fortran extensions to Fortran 95. A new Python module, CoArray, has been developed to provide co-array syntax that allows a ...

We present a significant extension of the quantified equation based algorithm class of piecewise regular algorithms. the main contributions of the following paper are: the class of piecewise regular algorithms are extended by allowing run-time dependent conditionals; a mixed integer linear program is given to derive optimal schedules of the novel class we call dynamic piecewise regular algorithms; and in order to achieve highest performance, we present a speculative scheduling approach. the results are applied to an illustrative example.
We describe a consistent splitting approach to the pressurestabilized Petrov-Galerkin finite element method for incompressible flow. the splitting leads to (almost) explicit predictor and corrector steps linked by an ...

Off-centers were recently introduced as an alternative type of Steiner points to circum-centers for computing size-optimal quality guaranteed Delaunay triangulations. In this paper, we study the depth of the off-cente...

In this article a parallel application for the 3D structural analysis of buildings is presented. Taking into account that solving the system of linear equations is the most time-consuming phase, several parallel publi...

this paper discusses the design and implementation of SDC, a new caching strategy aimed to efficiently exploit the locality present in the stream of queries submitted to a Web Search Engine. SDC stores the results of ...

Modern microprocessors have sacrificed the exactness of exceptions for improved performance long ago. this is a side effect of reordering instructions so that the microprocessor can execute instructions which were not...
