+libCEED is a lightweight library for expressing and manipulating operators that arise in high-order element-based discretization of partial differential equations.
+libCEED's representations are much for efficient than assembled sparse matrices, and can achieve very high performance on modern CPU and GPU hardware.
+This approach is applicable to a broad range of linear and nonlinear problems, and includes facilities for preconditioning.
