Abstract : We propose a method for emulating the behavior of your favorite MIMD computer on a network of workstations, so that programs written for the MIMD target can run on the distributed emulated version with just a recompilation. This is achieved by executing the computational parts as in the native run, with the message passing being simulated. The hardware of the target machine is simulated so that the behavior of the application is identical to a native run on the simulated computer with virtual timings and trace files. Moreover, our complexity analysis sets up the conditions required to achieve a good speedup as a function of the number of simulation hosts, the network latency and the granularity of the application.
