SLEPc stands for Scalable Library for Eigenvalue Problem Computations. With this library, it is possible to solve Eigenvalues and Eigenvectors. These problems are infamous in quantum mechanics. Before we go a little into details, we will download, configure, and compile the SLEPc extension library.
Download Version 3.4.4 from http://www.grycap.upv.es/slepc/download/download.htm.
SLEPc and PETSc must match in their main and first subversions. So, 3.4.4 and 3.4.1 are fine, and 3.5 and 3.1 will probably not work.
To install SLEPc, extract the archive with the following command:
tar –xf petsc-3.4.4.tar.gz
Go to the
petsc-3.4.4 subdirectory and type the following:
export PETSC_DIR=/var/mpishare/petsc-3.4.1 ...
