Applications, algorithms, and software for massively parallel computing

Sandia National Laboratories has developed massively parallel (MP) software that provides high absolute performance and nearly perfect parallel efficiencies. We have used this software on first- and second-generation 1K-processor hypercubes with more than thousand-fold parallel speedups and supercomputer performance. As we developed MP software, we made significant research advances in parallel numerical methods, such as parallel time stepping. The hardware diagnostic tools and parallel graphics algorithms that we have developed and provided to vendors can pinpoint hardware problems and visualize performance in thousand-processor ensembles. Our distributed-computing software will provide supercomputer performance from workstation networks. In collaboration with university and industry researchers in parallel computing, we have proven the concept of distributed parallel supercomputing with parallel computations on a network of VAX® computers.
