Macromolecular electron density averaging on distributed memory MIMD systems
نویسندگان
چکیده
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 iPSCj860 and on the Touchstone Delta system and uses a user controlled shared virtual memory and a dynamlc load balancing mechanism.

The design space of communication processors for message passing distributed memory systems is rather large. Many of the design decisions that are taken seem to be dependent on the targeted application, or application area, considering the various different communication hardware designs, commercial as well as research based, that have been presented. This paper describes a framework currently ...
