Scientific paper

We have developed a code which links scalar-mode fluctuations in the early universe with those observable at the present time by integrating the coupled, linearized, Einstein, Boltzmann, and fluid equations in a perturbed flat Robertson-Walker spacetime. The results are useful both for calculations of the cosmic microwave background anisotropy and the linear power spectrum of matter fluctuations. This paper introduces the serial and parallel codes, presents timing results, and gives sample output in graphical and animated form. This is a latex version containing most of an HTML-format technical paper submitted for Supercomputing '95.
