RPM enables rapid prototyping of different multiprocessor architectures. It uses hardware emulation for reliable design verification and performance evaluation. The major objective of the RPM project is to develop a common, configurable hardware platform to accurately emulate different MIMD systems with up to eight execution processors. Because emulation is orders of magnitude faster than simulation, an emulator can run problems with large data sets more representative of the workloads for which the target machine is designed. Because an emulation is closer to the target implementation than an abstracted simulation, it can accomplish more reliable performance evaluation and design verification. Finally, an emulator is a real computer with its own I/O; the code running on the emulator is not instrumented. As a result, the emulator looks exactly like the target machine (to the programmer) and can run several different workloads, including code from production compilers, operating systems, databases, and software utilities
