abstract = {Numerically addressing scientific questions such as
simulating drug diffusion through the human stratum corneum
is a challenging task requiring complex codes and plenty of
computational resources. The UG4 framework is used for such
simulations, and though empirical tests have shown good
scalability so far, its sheer size precludes analytical
modeling of the entire code. We have developed a process
which combines the power of our automated performance
modeling method and the workflow manager JUBE to create
insightful models for entire UG4 simulations. Examining
three typical use cases, we identified and resolved a
previously unknown latent scalability bottleneck. In
collaboration with the code developers, we validated the
performance expectations in each of the use cases, creating
over 10,000 models in less than a minute, a feat previously
impossible without our automation techniques.},
