Using PETSc to develop scalable applications for next-generation power grid

Developing scalable software for existing and emerging power system problems is a challenging task and requires a great deal of concentrated time and effort. This effort can be reduced by using high performance computing software li-braries, such as PETSc, which are tested on a gamut of scientific applications, used on single core machines to su-percomputers, have highly optimized implementations, and a wide array of tested numerical solvers. Using high per-formance computing libraries for developing power system applications is not yet done in the power system commu-nity but well-explored by researchers doing PDE simula-tions. The goal of this paper is to introduce the high perfor-mance computing library PETSc and motivate using such high performance computing libraries for developing exist-ing and future power system applications
