Abstract

To get a clear picture of the earth crust the Helmholtz equation needs to be
solved and a high wave number is needed in order to provide fine grain details.
The Stabilised BiConjugate Gradient method needs to be implemented to solve
the Helmholtz equation. This is done on a Maxeler data flow machine to improve
calculation times. The algorithm is split into 3 parts and all of them use the same
calculation kernel. An improvement in calculation time of 2.4 times faster than in
the literature is achieved and a two times faster calculation is expected with more
modern hardware. Maxeler’s data flow machine shows great possibilities to decrease calculation times for high performance computing problems.
