Domain decomposition methods for parallel laser-tissue models with Monte Carlo transport

PDF Version Also Available for Download.

Description

Achieving parallelism in simulations that use Monte Carlo transport methods presents interesting challenges. For problems that require domain decomposition, load balance can be harder to achieve. The Monte Carlo transport package may have to operate with other packages that have different optimal domain decompositions for a given problem. To examine some of these issues, we have developed a code that simulates the interaction of a laser with biological tissue; it uses a Monte Carlo method to simulate the laser and a finite element model to simulate the conduction of the temperature field in the tissue. We will present speedup and ... continued below

We will present speedup and load balance results obtained for a suite of problems decomposed using a few domain decomposition algorithms we have developed.
