The Earthquake Problem and a Computational Advancement

A newsletter from our technical partner SiOmec.

In May 2015, Dr. Norbert Schwarzer was invited to the geology department at Ohio State University and gave a presentation about his work. During that presentation he was asked to model a certain earth-layer situation that apparently was considered a very difficult problem by the audience, and which usually requires super-computers to be simulated. Norbert used the software (his own FilmDoctor) on his laptop computer and had the result in a few seconds. The audience had expected either total failure or endless evaluation time. So, you can picture quite some jaw dropping.

As a mere byproduct, a new mechanical failure mechanism was discovered which had puzzled and molested many engineers for many years in the coating industry (see Figure 1).

Witness: Prof. Michael Bevis, Ohio State University

Figure 1. The Paradox Double Eggshell Effect

A Computational Advance

Now a recent test of FilmDoctor being developed to run on 64-bit instead of 32-bit operating system architecture has shown the calculation times to be dramatically improved (see Figure 2). The 64-bit version allows much better multitasking and data handling with better utilization of a computers available RAM memory.

Figure 2. At left a 2-layer system (hard layer over incompressible layer over hard substrate) leading to the double eggshell effect. At right various computation times for different problem types using a 4 core CPU and comparing 32-bit and 64-bit versions. The computation evaluation software allows to compare different numbers of CPU cores, different resolution and for a variety of different n-dimensional problem types. The yellow highlight shows the calculation times for the 2-layer system.

The Result, this 2-layer double eggshell example would normally take 3 seconds is now calculated in 1 second. Imagine not having to schedule days, weeks, or months of super compute time to get the answers you need faster and provide a competitive advantage.
