In this episode of Let’s Talk Exascale, Mark Taylor of Sandia National Laboratories talks about using exascale supercomputers for severe weather and water resource forecasting. A sub-project within the US Department of Energy’s (DOE’s) Exascale Computing Project (ECP) called E3SM-MMF is working to improve the ability to simulate the water cycle and the processes around precipitation. Our guest on the latest episode of ECP’s podcast, Let’s Talk Exascale, is Mark Taylor of Sandia National Laboratories, principal investigator of the E3SM-MMF project.
