z-Pares
z-Pares is an app for obtaining the eigenvalues and eigenvectors for general sparse matrices using the contour integrals in the complex plane, i.e., Sakurai-Sugiura method. z-Parels is written in fortran 90/95 and supports the large scale parallelization via the two-level MPI distributed parallelism.
