Compared on physics simulation software

Purpose: libCEED is a library for matrix-free operator representation, with runtime selection of implementations for CPUs and GPUs.
Target users: Its low-level API is intended for application code with its own discretization infrastructure, including PETSc, MFEM, and Nek5000.
Methods: The library focuses on high-order finite elements, while its algebraic approach also applies to other discretizations in factored form.
Language interfaces: The C99 library has Fortran, Python, Julia, and Rust interfaces.
CPU and GPU backends: Documented backends include CPU implementations and GPU implementations using CUDA, HIP, SYCL, and MAGMA.
Build dependencies: The library has no required dependencies; CUDA, HIP, and SYCL support can be enabled during the build, and SYCL requires oneAPI compilers.
Integration: The manual describes libCEED as a lightweight library that can be integrated into new and legacy software through a purely algebraic interface.
Reproducibility limit: Some backends use nondeterministic operations, and the manual identifies which backends can produce reproducible results with proper compilation options.
Backend requirements: The documented HIP backends require ROCm 4.2 or newer, and the MAGMA backends require MAGMA 2.5.0 or newer.
Support: The project repository says users can contact the libCEED team by email or leave a comment in the issue tracker.
License: The repository identifies the software as BSD-2-Clause licensed.
