摘要

The MCHF package is a suite of programs that enable the calculation of atomic data required by many science and engineering disciplines. As a means of meeting its high computational demands, the package has previously been implemented in PVM. The codes have been used on a dedicated cluster of workstations with a static load balancing scheme. However, the cluster needs to be shared with other users, and different architecture workstations need to be embedded. In this paper, modifications of two well-known dynamic load balancing schemes are implemented and tested. The resulting codes exhibit perfect load balancing for a variety of system loads, facilitating the solution of large problems and the efficient utilization of current resources.
