WarpX Exascale Update - New Platforms, Functionality and Applications
ORAL
Abstract
We present the latest results on the development of WarpX, an advanced electromagnetic particle-in-cell code from the U.S. Exascale Computing Project. With the introduction of the first Exascale machines, we present results on new GPU architectures. We also give an overview of new algorithms and functionalities, including scalable in situ analysis and visualization, new applications beyond laser-plasma accelerators and the development of an international open source ecosystem around WarpX.
