Abstract
The bound states of Van Der Waals Molecules are computed using iterative eigenvalue solver implicitly Restarted Lanezos Method (IRLM). In this application two techniques two used to make the calculation more efficient. First Chebychev preconditioning is used to speedup the convergence. Secondly tensor product technique is used program is many times faster than eispack routines. The parallelization of the program on Cray-T3D shows that the program also scales well on multi-processor supercomputers.
