This repository provides a framework for automatically generating or downloading matrix datasets and benchmarking various numerical solvers. The suite supports multiple solvers, including KLU, NICSLU, ...

Abstract: The sparse matrix solver has become a bottleneck in simulation program with integrated circuit emphasis (SPICE)-like circuit simulators. It is difficult to parallelize the solver because of ...

Abstract: Conventionally, the large sparse matrix equation ($Ax=b$) generated by the Laguerre-FDTD method is computed using direct matrix solvers, which is often ...

The underlying solver algorithms used in power grid (PG) simulation today are derivations of circuit simulation algorithms first developed many decades ago. In fact, the 40 th anniversary of SPICE (a ...
