Abstract

Building a scalable and low cost parallel computing environment is becoming a critical matter for scientific computing that requires the repetitive solutions of large linear systems. In this study, a PCI Express based PC cluster is built for the scalable implementation of parallel iterative linear solvers, and the performance and bottlenecks are evaluated. The results show that the communication bandwidth of the internode network is the most important factor for the scalable implementation of parallel sparse linear algebra operations.
