direct execution and parallel simulation. In direct execution, a program from the target system runs on an existing host system. 1 For example, a target's floating-point multiply executes as a floating-point multiply instruction on the host. The host calculates the target's execution time and simulates only those operations unavailable on the host. Direct(More)
Analysis of future parallel computers requires rapid simulation of target designs running realistic workloads. These simulations have been accelerated by two techniques: direct execution and the use of a parallel host. Historically, these techniques have been considered to lack portability. We identify four key operations necessary to make these simulations(More)
