Ghysels et al. torus 2 | Novel algorithm delivers flexibility, efficiency for sparse linear system solvers on HPC infrastructures

The second-order Maxwell equation on a toroidal domain is discretized using Nédélec finite elements using the MFEM package developed by the Center for Efficient Exascale Discretizations, an ECP co-design center. The resulting large sparse linear system was solved using the STRUMPACK sparse direct solver on OLCF’s Summit machine.
