Given the steady increase in cores per CPU, it is only a matter of time before supercomputers will have a million or more cores. In this article, we investigate the opportunities and challenges that will arise when trying to utilize this vast computing power to solve a single integer linear...

Atmospheric air quality modeling relies in part on numerical simulation. Required numerical simulations are often hampered by lack of computer capacity and computational speed. This problem is most severe in the field of global modeling where transport and exchange of trace constituents are...

The article describes a solution to process large volumes of unstructured health social media data in a scalable fashion using the MapReduce framework. Our work is in the context of health informatics applications involving complex text and language processing as well as large resources such as...

This paper shows how to build algorithms that use graphics processing units (GPUs) installed in most modern computers to solve dynamic equilibrium models in economics. In particular, we rely on the compute unified device architecture (CUDA) of NVIDIA GPUs. We illustrate the power of the approach...

The numerical solution of very large three-dimensional electromagnetic field problems are challenging for various applications in the industry. In this paper, we propose a nonoverlapping domain decomposition approach for solving the three-dimensional Maxwell equations on MIMD computers, based on...

This article examines the welfare effects of international income transfers in a two-country, two-good model with transboundary pollution. Most existing studies have assumed that pollution negatively affects the consumer’s utility function instead of influencing production. In our model, there...
