The paper discusses algorithms and programs for electron density averaging using a distributed memory MIMD system. Electron density averaging is a computationally intensive step needed for phase refinement and extension in the computation of the 3-D structure of macromolecules like proteins and viruses. The determination of a single structure may require thousands of hours of CPU time for traditional supercomputers. The approach discussed in this paper leads to a reduction by one to two orders of magnitude of the computing time. The program runs on an Intel iPSC/860 and on the Touchstone Delta system and uses a user controlled shared virtual memory and a dynamic load-balancing mechanism. |
