摘要：

Electron-density averaging, fast Fourier synthesis and fast Fourier analysis programs have been adapted for parallel-computing systems. These have been linked to perform iterative phase improvement and extension utilizing non-crystallographic symmetry and solvent flattening. Various strategies for parallel algorithms have been tested on a variety of computers as a function of the number of computer nodes. Some experimental timing results are discussed.
