Large-Scale Computation of Pi on a Compute Cluster
DescriptionWe describe an effort to compute pi to high precision using a distributed memory approach on a compute cluster. The work is an example of how one can use parallelism and the aggregate RAM of a cluster to greatly accelerate a computation that would otherwise use external storage to hold state. The cost of our approach is some programming complexity and the need for significant hardware resources (albeit for short periods of time) to realize the run-time saving on large-scale problems. The main goal motivating this work is the creation of a holistic benchmark that can be used to test a supercomputer in several critical dimensions: compute cores, memory, network, and storage. We expect that the code produced by this effort leads to fruitful interaction with the many talented people engaged in scientific computing efforts across the country.
