GPU-Based Lattice QCD Simulations as Thermometer for Heavy-Ion Collisions
Abstract:
See how advances in GPU Computing enable us to simulate Quantum Chromodynamics and learn about fundamental properties of strongly interacting matter i.e., quarks and gluons at finite temperatures. With the advances in hardware and algorithms these simulations have reached a level that allows for a quantitative comparison with experimental data from heavy-ion colliders. Discover how the Kepler architecture helps us to boost the performance of the simulations and reach new level of precision. I will discuss selected optimizations for the Kepler K20 cards and modifications to prepare the code for the Titan supercomputer. Furthermore I compare and discuss pros and cons of our in-house in comparison to available libraries like the QUDA library.
