....slow to evaluate system level performance. Real applications on parallel machines run for billions, or even trillions of cycles; even register transfer level simulators are much too slow. Over the last several years, direct execution has become widely used to accelerate architectural simulations [6, 4, 3, 7, 14]. Direct execution exploits the common ality between the instruction set of the simulated target machine and the underlying host system. For example, a floating point multiply on the target is simulated by executing a floating point multiply on the host. Such a system need only simulate the ....

....by executing a floating point multiply on the host. Such a system need only simulate the differences between the target system and the host, achieving impressive performance when the two systems are very similar. Simulations of parallel computers have exploited di rect execution in several ways [3, 7, 5]. Most commonly, a parallel target system is simulated on a uniprocessor host. For example, the Tango system spawns an event generation process for each processor in a target sharedmemory system. These processes directly execute all computation instructions, but must send most memory references to ....
