A few days ago the applications that are going to be used as benchmarks for the competition were announced: GROMACS (simulation of molecular dynamics), MILC (numerical simulations related to quantum chromodynamics) and WRF (numerical weather prediction system). Additionally two secret benchmarks will be announced at the competition.
In view of these public benchmarks we can now evaluate the possible hardware configurations to find out what system will provide the best performance. Therefor we have to discover the peculiarities of each application and make out possible bottlenecks. On the software side we are testing different versions of compilers, libraries, MPI implementations, etc. to figure out the best set of settings for each application.
