The future of simulation: A field of dreams

Quantitative evaluation of next-generation computer architectures and processor enhancements is possible only by running simulations. However, since the insights that are gained through simulation are predicated on the accuracy of the simulation results, and since the design decisions for future processor architectures -- which cost billions of dollars to design and implement -- are based on those insights, periodic examination of the simulation process becomes a necessity, rather than a luxury. Accordingly, this panel discusses the deficiencies of existing simulators, benchmarks, and simulation methodologies and techniques, and, in addition, what future directions are available for each.
