This month Shiquan Su (NCAR) and Chat Burdyshaw (NICS) will be talking about their work with PI David Gubbins at the Scripps Institution of Oceanography at UCSD. This project characterizes a geodynamo simulation code for paleomagnetic observations targeted to run on TACC Stampede2 KNL cluster; a hybrid, distributed many-core parallel architecture. Issues examined are parallel scaling across distributed nodes and within the many core architecture, as well as vectorization efficiency, arithmetic intensity and memory throughput.

This presentation includes two parts. In the first part, Shiquan Su from NCAR will introduce the background of the project, the parallelization algorithm, the experience on Stampede KNL cluster, OpenMP treatment, and the two approaches to run the project jobs on the machines. In the second part, Chad Burdyshaw from UTK takes a close look at the code. Chad will discuss the tools used to interrogate performance, observations, remedies, and potential solutions.
