German and Russian scientists join forces to improve performance tuning on supercomputers
To better understand the efficiency of programs on supercomputers, scientists rely on performance measurements. However, these also reflect random delays, for example, caused by concurrently running programs running. The performance of the actual algorithm is therefore difficult to evaluate. In a German-Russian joint project, coordinated by computer science professor Felix Wolf at TU Darmstadt, partners from Darmstadt, Jülich and Moscow are working on less sensitive analysis methods.
