AMReX and pyAMReX: Looking Beyond ECP
AMReX is a software framework for the development of block-structured mesh applications with adaptive mesh refinement (AMR). AMReX was initially developed and supported by the AMReX Co-Design Center as part of the U.S. DOE Exascale Computing Project, and is continuing to grow post-ECP. In addition to adding new functionality and performance improvements to the core AMReX framework, we have also developed a Python binding, pyAMReX, that provides a bridge between AMReX-based application codes and the data science ecosystem. pyAMReX provides zero-copy application GPU data access for AI/ML, in situ analysis and application coupling, and enables rapid, massively parallel prototyping. In this paper we review the overall functionality of AMReX and pyAMReX, focusing on new developments, new functionality, and optimizations of key operations. We also summarize capabilities of ECP projects that used AMReX and provide an overview of new, non-ECP applications.
Once in a blue moon I can work for a hot evening on binary hackery - like this for #AMReX ππ

We have big news!
Today, we announced that #WarpX and #AMReX intent to join an open foundation for High Performance Software (#HPSF). With this step, we acknowledge & foster our tremendously valuable international scientific contributor and scientific user base, elevating project governance to the same, international, open level.

Alex RybchukI'm getting some practice in with the #amrex AMR-Wind LES code this week in preparation for some DOE AWAKEN runs. Here's a bird's eye view of winds for three turbines in a row. You can see the wakes get progressively stronger as you move from left to right
