... We have performed a series of tests to find an optimal data distribution in the Cray T3D memory, and to identify a strategy for the Dynamic Load Balance (DLB). ... N-body simulations are one of the most important tools in contemporary theoretical cosmology, however the number of particles required to reach a significant mass resolution is more larger than those allowed even by present-day state-of-the-art massively parallel (Gouhing 1995; Romeel 1997 & Salmon 1997) supercomputers (hereafter MPP). ...

... In our numerical experiments we have mainly considered two test objects provided by R. Hanisch and characterized by different types of brightness distribution; one of the objects simulates an elliptical galaxy and the other one a star cluster with size 512 512 and 256 256 pixels, respectively. ... The best performances in the restoration of the star cluster image are provided by the R-L algorithm and the LWPOS one; they give accuracies of 6%and 5%, respectively (see Table 1). ...

... The obtained results lead to the following conclusions: a) the heavy element enrichment had taken place in the Galaxy in a few bursts of its activity rether than in a continuons manner; b) these bursts occured during the callapse of the early Galaxy; c) the star formation had been inhibited in the time of the bursts; d) the metal enrichment did not proceed in the periods of star formation, between these bursts of activity. ...
