AWS unveils the newest open-source software called Palace, which stands for ‘PArallel, LArge-scale Computational Electromagnetics,’ it is a parallel finite element code for full-wave electromagnetics simulations. The AWS Center for Quantum Computing used Palace to run large-scale 3D simulations of complex electromagnetic models and to facilitate the construction of quantum computing hardware.
Palace is designed with cloud scalability and elasticity; the developers took advantage of Amazon’s cloud-based high-performance computing (HPC) products and services. Palace is now accessible on GitHub as an open-source project for electromagnetic modeling workloads, including those in quantum computing, that users may run on platforms ranging from their personal laptops to supercomputers.
The Elastic Fabric Adapter (EFA) equipped in Palace
Palace delivers cutting-edge performance by leveraging scalable techniques and implementations from the scientific computing community and recent advances in computational infrastructure. This incorporates the Elastic Fabric Adapter (EFA) for fast networking and HPC-optimized Amazon Elastic Compute Cloud (EC2) instances with customized Intel or AWS Graviton processors for superior price performance on AWS.
These types of open-source software, such as Palace, enable users to use elastic cloud-based HPC to run unlimited simulations in parallel when examining huge parametric design spaces without being confined by commercial software licensing models.
Finally, while numerous highly performant, open-source tools exist for various computational physics applications, few open-source solutions exist for massively parallel, finite element-based computational electromagnetics.
Palace features multiple simulation types.
Palace offers various simulation types, including eigenmode analysis, frequency and time domain-driven simulations, and electrostatic and magnetostatic simulations for fully coupled extraction. Furthermore, the software can simulate a superconducting metamaterial waveguide built from a series of lumped-element microwave resonators. As an open-source project, it is also completely extendable by developers wishing to add new functionality for industrially relevant challenges.
The MFEM finite element discretization library, which enables high-performance, scalable finite element research and application development, is important in developing a large portion of Palace.
