In-Situ Inference for Exascale Simulations with Julia
Ayan Biswas, Earl Lawrence

Exascale simulations, like those of interest to the Department of Energy, will produce more data than can be stored for post hoc statistical analysis. To address this, we are using Julia as an HPC-embedded language to develop workflows for statistical analysis inside simulations as they run. Our project, PRISM, is being developed to fit Bayesian hierarchical models to answer scientific questions using the high resolution data that will be produced on the next generation of supercomputers.
