The main computations in finite element analysis are basic linear algebra operations on matrices and vectors, and even load distribution is suitable for these parallel computations. Therefore, parallel FEM codes implemented with OpenMP and simple scheduling often achieve good efficiency in conventional multi-core processors. However, in recent years, desktop CPUs such as Intel's Alder Lake and Apple's M1 have adopted heterogeneous architectures with high-efficiency and high-performance cores. Therefore, it is unclear whether the conventional parallel FEM code can extract the processor's performance on those parallel computers. This research evaluates the performance of a heterogeneous processor using a parallel FEM code that uses the conjugate gradient method as a linear solver and discusses the results.
