Efficient use of parallel libraries on heterogeneous networks of workstations

A heterogeneous network of workstations (NOW) introduces a new performance factor into distributed computing: a large variation of the computing power of the different workstations. This unique factor makes traditional performance models/metrics for ...

Performance debugging and prediction for parallel systems is a difficult problem. The difficulties in identifying performance bottlenecks stem from the need for an intimate understanding of the underlying architecture. It has been recognized that ...

We study the computational, communication, and scalability characteristics of a computational fluid dynamics application, which solves the time-accurate flow field of a jet using the compressible Navier-Stokes equations, on a variety of parallel ...
