 rs, among the largest, most complex devices, demand increasingly sophistic
 ated computational tools for the design and optimization of the next gener
 ation of accelerators that will meet the challenges of increasing energy, 
 intensity, accuracy, compactness, complexity and efficiency. It is key tha
 t contemporary software take advantage of the latest advances in computer 
 hardware and scientific software engineering practices, delivering speed, 
 reproducibility and feature composability for the aforementioned challenge
 s. We will describe the Exascale software stack that is being developed at
  the heart of the Beam pLasma Accelerator Simulation Toolkit (BLAST). As a
  highlight, we present how the US DOE Exascale Computing Project (ECP) app
 lication WarpX uses the power of GPUs at scale, which won the 2022 ACM Gor
 don Bell Prize. We will present performance results on the first Exascale 
 supercomputer for the modeling of laser-plasma acceleration. We then descr
 ibe how we are leveraging the ECP experience to develop a new generation e
 cosystem of codes that, combined with machine learning, will enable modeli
 ng from the ultrafast to the ultraprecise for future accelerator design an
 d operations.\n\nDomain: Engineering\n\nSession Chair: Jeremy Johnathan Wi
