The calculation of eigenvalues and eigenfunctions of one-dimensional cuts of reactive potentials is often a key step of scattering calculations of higher dimensions. Parallelized versions of related computer codes do not consider a parallelization at the level of individual eigenvalue calculations. In this paper we present an attempt to push the parallelism to this level and compare the sequential and parallel performances of the restructured code.

Abstract
The calculation of eigenvalues and eigenfunctions of one-dimensional cuts of reactive potentials is often a key step of scattering calculations of higher dimensions. Parallelized versions of related computer codes do not consider a parallelization at the level of individual eigenvalue calculations. In this paper we present an attempt to push the parallelism to this level and compare the sequential and parallel performances of the restructured code.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
