Abstract [en]

We examine computing alternative solutions to a problem in parallel to improve response time.Problems with exploring multiple alternatives in parallel include (1) side-effects and (2) combinatorial explosion inthe amount of state which must be preserved. These are solved by process management and an application of‘‘copy-on-write’’ virtual memory management. The side effects resulting from interprocess communication are handledby a specialized message layer which interacts with process management. The effect is to create ‘‘MultipleWorlds’’, which are different due to the alternate solution methods, but internally self-consistent.We show how such a ‘‘Multiple Worlds’’ scheme can be used for several applications.
