Martin, W R; Nowak, P F

The vectorized Monte Carlo photon transport code VPHOT has been developed for the Cray-1, Cray-XMP, and Cray-2 computers. The effort in the current project was devoted to multitasking the VPHOT code and implement it on the Cray X-MP and Cray-2 parallel-vector supercomputers, examining the robustness of the vectorized algorithm for changes in the physics of the test problems, and evaluating the efficiency of alternative algorithms such as the ''stack-driven'' algorithm of Bobrowicz for possible incorporation into VPHOT. These tasks are discussed in this paper. 4 refs.
