A Parallel Grid Based PSE for EHL Problems
نویسندگان
چکیده
In this paper we explain how a Problem Solving Environment (PSE) can be constructed such that the computationally intensive sections are run using resources on the Computational Grid, operating remotely from the machine running the visualisation. The PSE in question is one solving demanding elastohydrodynamic lubrication problems from mechanical engineering. The numerical calculation is done here using both multilevel techniques and using parallelism. The global nature of the equation system behind the problem means that, given that this is a communications intensive calculation, the code scales remarkably well.

Web-based Grid PSE for MD Simulations using Grid PSE Builder
In large-scale scientific simulations, we sometimes have access to supercomputers and largescale cluster systems of appropriate computer centers at remote sites as a way of obtaining large scale computer resources. In this case, some difficulties in using such resources due to differences in rules and job execution at each computer center have been found. Differences among remote sites to be ac...
