Abstract
The implementation of the HONDO program on the Loosely Coupled Array of Processors (LCAP) parallel computer system assembled in our laboratory is presented. We discuss a general strategy used to maintain a high level of compatibility between the serial version and the parallel version of the code. We report the implementation of energy-gradient calculation for SCF wavefunctions. The integral and integral derivative programs display high parallel efficiency, and so does the SCF part in the case of very large basis sets.
