We present libvdwxc, a general library for evaluating the energy and
potential for the family of vdW-DF exchange–correlation functionals. libvdwxc is
written in C and provides an efficient implementation of the vdW-DF method and
can be interfaced with various general-purpose DFT codes. Currently, the Gpaw
and Octopus codes implement interfaces to libvdwxc. The present implementation
emphasizes scalability and parallel performance, and thereby enables ab initio
calculations of nanometer-scale complexes. The numerical accuracy is benchmarked
on the S22 test set whereas parallel performance is benchmarked on ligand-protected
gold nanoparticles (Au144(SC11NH25)60) up to 9696 atoms.
