Physicists and computer scientists at the U.S. Department of Energy's Argonne National Laboratory (ANL) recently executed the Last Journey, a massive cosmological simulation, on the Mira supercomputer, concluding the system's seven-year operational lifetime.
The model tracks the distribution of mass across the universe over time, detailing gravity's effect on dark matter to aggregate into halos within which galaxies form.
ANL scientists used the Hardware/Hybrid Accelerated Cosmology Code and its CosmoTools analysis framework to facilitate incremental extraction of relevant data while the simulation was running.
ANL's Adrian Pope said, "When preparing for simulations on exascale machines and a new decade of progress, we are refining our code and analysis tools, and we get to ask ourselves what we weren't doing because of the limitations we have had until now."
