Lattice QCD Thermodynamics on the Grid

Understand

We describe how we have used simultaneously ${\cal O}(10^3)$ nodes of the EGEE Grid, accumulating ca.

• 300 CPU-years in 2-3 months, to determine an important property of Quantum Chromodynamics.
• We explain how Grid resources were exploited efficiently and with ease, using user-level overlay based on Ganga and DIANE tools above standard Grid software stack.
• Application-specific scheduling and resource selection based on simple but powerful heuristics allowed to improve efficiency of the processing to obtain desired scientific results by a specified deadline.
