Memory and Timing

The Table 1 summarizes performance data for the simulations, which were performed on an Silicon Graphics Power Challenger with 16 processors and 2 GB of RAM. All results used in this study were obtained using a single processor. Some preliminary performance results for the parallel version of Eclipse, based on PVM and a distributed memory algorithm, are also given. The number of CPUs used is given in parenthesis.
