GPU computing for numerical relativity — •Andreas Weyhausen, Bernd Brügmann, and Jason Grigsby — Theoretisch-Physikalisches Institut, FSU Jena

Numerical Relativity (NR) allows to study physically interesting space times like binary black hole systems by solving Einsteins equations using numerical methods. As this is computationally expensive NR always looks for ways to speed up the simulations. At the moment it is popular in high performance computing to use graphics cards to speed up applications. These have developed from special purpose devices to powerful highly parallel accelerators which outnumber the theoretical peak floating point operations per second performance of CPUs by a factor up to two magnitudes. In my talk I will give an introduction to Numerical Relativity and GPU Computing and I will discuss the question if NR can benefit from using graphics cards.
