摘要：
Computer simulations of the encounter of a satellite galaxy with a host galaxy are described. These are being carried out using tree-code gravity on an NCUBE parallel processor with 128 processors. The particles of the host - representing both stars and gas - are distributed over the processors, and the potential of the whole ensemble is calculated using a fast parallel communications algorithm to pass information between the processors, with the result that the amount of processing and communications scales as log N where N is the number of particles.
