John Michalakes is a computer scientist and an expert in high-performance computing for earth system applications with NREL's Computational Science Center. He is working with NREL scientists on applying efficient, high-end computing infrastructure to wind energy research and prediction over scales ranging from sub-millimeter at turbine blade surfaces to mesoscale and larger scale atmospheric processes. Michalakes came to NREL from the National Center for Atmospheric Research (NCAR) where he led the software effort to design and build the Weather Research and Forecast (WRF) model. He was lead author on an SC'07 Gordon Bell finalist paper wherein WRF is scaled to record parallel threads of execution. Prior to work at NCAR, he worked at Argonne National Laboratory and was on the DOE team that developed the first parallel implementations of the NCAR Community Climate Model. Michalakes has developed tools and techniques for parallelizing large community models and systems of coupled models. His current research includes investigating GPU and other acceleration technology for earth system models.
