“…In a review of vectorized Monte Carlo, Martin and Brown 281 described variations of event-based algorithms together with speed-up results published by different groups. During the last two decades, investigations were carried out to run different Monte Carlo codes on multipletransputer systems, 282,283 vector parallel supercomputers, 266,267,284,285 parallel computers 38,286,287 and a cluster of workstations in a local area network using PVM. 288 There are large discrepancies in the performance ratio reported by different authors.…”
