SLEPc, which stands for Scalable Library for Efficient Solution of Eigenvalue problems, is a widely used library designed for solving large-scale eigenvalue problems and linear symmetric eigenvalue problems, particularly in the context of scientific and engineering applications. It is built as an extension of the Portable, Extensible Toolkit for Scientific Computation (PETSc) and focuses on harnessing high-performance computing resources to handle problems that involve massive matrices.
