Powerful, low-cost clusters of personal computers, such as Beowulf clusters, have fueled the potential for widespread distributed computation. While these Beowulf clusters typically have software that facilitates development of distributed applications, there is still a need for effective distributed computation that is transparent to the application programmer. This paper describes the design ...

This paper uses the parallel calculation of the radiation integral for examination of performance and compiler issues on a Beowulf-class computer. This type of computer, built from mass-market, commodity, of-the-shelf components, has limited communications performance and therefore also has a limited regime of codes for which it is suitable. This paper first shows that this code falls within th...

The Scientific Computation Research Center (SCOREC) was established jointly by the Schools of Engineering and Science at Rensselaer Polytechnic Institute. SCOREC models real world physical reactions by simulating them on computers. The numerical solution of these models often requires discretizations with a number of unknowns approaching one billion. Problems of this scale can only be solved on...
