SLEPc: Scalable Library for Eigenvalue Problem Computations

SLEPc is a software library for the solution of large scale sparse eigenvalue problems on parallel computers. It is an extension of PETSc and can be used for either standard or generalized eigenproblems, with real or complex arithmetic. It can also be used for computing a partial SVD of a large, sparse, rectangular matrix, and to solve nonlinear eigenvalue problems

Note

To install PETSc, SLEPc, petsc4py, and slepc4py (mpi4py is optional but highly recommended) use:

$ python -m pip install numpy mpi4py  (or pip install numpy mpi4py)
$ python -m pip install petsc petsc4py (or pip install petsc petsc4py)
$ python -m pip install slepc slepc4py (or pip install slepc slepc4py)

Tip

You can also install the in-development versions with:

$ python -m pip install Cython numpy mpi4py
$ python -m pip install --no-deps https://gitlab.com/petsc/petsc/-/archive/main/petsc-main.tar.gz
$ python -m pip install --no-deps https://gitlab.com/slepc/slepc/-/archive/main/slepc-main.tar.gz

Provide any SLEPc ./configure options using the environmental variable SLEPC_CONFIGURE_OPTIONS.
