Solving bigger problems -- by decreasing the operation count and increasing the computation bandwidth
Article Abstract:
Computational electromagnetics are viewed from the perspectives of total number of computation operations required to reach the desired information and approaches that might reduce that number and the future capabilities of the modeling approaches for computational bandwidth applications. Total operation count can increase so fast and with such increasing frequency that computer floating-point operation rate magnitude speedups are really only small increases in the frequency for clock-time problem resolution. Computational realities limit modeling in current integral-equation- and differential- equation- based numerically rigorous models, but numerical techniques are still practically useful for many sets of problems. Massive parallelism will likely be well-suited to differential-equation models since a single processor could handle one or more nodes in the model mesh.
