The weight, w k , is determined from a scheme employing the Voronoi polyhedron proposed by O'Keeffe, O k w k is the solid angle determined by the face of the Voronoi polyhedral separating the atom k and the atom p, and θ (p) max is the maximum among all the solid angles. We use DScribe to obtain Coulomb, Sine and Ewald Sum matrices. DScribe is a Python package for transforming atomic structures into fixed-size numerical descriptors. To measure the computation speed of these matrices, we took 3,000 random structures from the OCP dataset and measured the average computation time of parallel execution. Thus, we obtained the following results: Coulomb matrix -0.66 ms/structure, Sine matrix -0.913 ms/structure, Ewald Sum matrix -7.96 ms/structure. Computations were done on 15 cores of AMD EPYC 7501 32-core 64-thread 2.0GHz processor.
