Abstract

Fault simulation is a computer-intensive problem. Parallel processing is one method to reduce simulation time. In this paper, we discuss a technique to partition the fault set for fault-parallel simulation on multiple processors. When applied statically, the technique can scale well for up to 32 processors. The fault-set partitioning technique is simple and can itself be parallelized. Existing uniprocessor algorithms, based on parallel-pattern simulation, can be used for multiprocessor simulation without modification. Therefore, the techniques can be used effectively on a low-cost parallel resource such as a network of workstations.
