TIME: 14.30

ABSTRACT:
Heterogeneous computing systems have recently come to the forefront of the High-Performance Computing (HPC) community's interest. Large-scale heterogeneous computing systems have consistently ranked highly on the Top500 list since the beginning of the heterogeneous computing trend. By using heterogeneous computing systems that consist of both general purpose processors and special-purpose accelerators, the speed and problem size of many simulations can be dramatically increased. Ultimately, this results in enhanced simulation capabilities that allows, in some cases for the first time, the execution of parameter space and uncertainty analyses, model optimizations, and other inverse modeling techniques that are critical for scientific discovery and engineering analysis. However, simplifying the usage and optimization of codes for heterogeneous computing systems remains a challenge. This is particularly true for scientists and engineers for whom performance analysis and understanding HPC architectures may not be primary research objectives. A modular environment for geophysical inversion and run-time auto tuning on heterogeneous computing systems is presented which enables scientists and engineers to remain focused on their primary research objectives.

BIO:
Joe Myre took his B.S. in Computer Science at the University of Wisconsin - Eau Claire in 2008. He then went to pursue a Ph.D. in Computer Science at the University of Minnesota which he completed in 2013. His Ph.D. encompassed high-performance scientific computing with an applied focus in geology. During that time he developed an enthusiasm for speleology and karst hydrogeology. He is currently pursuing this through a National Science Foundation Postdoctoral Fellowship at the University of Arkansas where he is studying the morphogenesis of soluble bedrock forms.
