We describe the parallel implementation of our generalized stellar atmosphereand NLTE radiative transfer computer program PHOENIX. We discuss the parallelalgorithms we have developed for radiative transfer, spectral line opacity, andNLTE opacity and rate calculations. Our implementation uses a MIMD design basedon a relatively small number of MPI library calls. We report the results oftest calculations on a number of different parallel computers and discuss theresults of scalability tests.Comment: To appear in ApJ, 1997, vol 483. LaTeX, 34 pages, 3 Figures, uses AASTeX macros and styles natbib.sty, and psfig.st
