IVHS traffic modeling using parallel computing: performance results

The THOREAU simulation of vehicular traffic on city streets and freeways, developed by MITRE Corporation, has been adapted to run in parallel on a network of Unix workstations connected by ethernet. Tenfold and larger speedups were many as 40 parallel threads on 34 processors. The performance curves show little sign of leveling off with higher degrees of parallelism, which may mean that further gains can be obtained with more processors.<>
