Somebody hand-translated a few standard OPS5 benchmarks (such as monkey-and-bananas) into Prolog and found that the Prolog versions, even using C-Prolog, were much faster than the OPS5. I don't recall seeing anything at that time about an automatic translator, though...but this shows that such a gadget might be useful. Then again, there's been some talk recently of optimizing compilers for OPS5, and even of something vaguely resembling a WAM (it's a building-block of the PESA-1 machine, if memory serves, not a stand-alone serial machine like the WAM). Therefore, implementations of OPS5 seem slowly to be coming up to the standard for those of Prolog. Anybody have more details? Mark. Gooley, gooley@s.cs.uiuc.edu
