ARPACK is a collection of Fortran77 subroutines designed to solve large scale eigenvalue problems.

On the HPC we have versions for all the compilers that we support: gnu,intel and pgi. To use the arpack library, you have to compile your source like,

g77 -o myprogram myprogram.f -L/opt/arpack/gnu -larpack

ifort -o myprogram myprogram.f -L/opt/arpack/intel -larpack

pg77 -o myprogram myprogram.f -L/opt/arpack/pgi -larpack
