If today's tech gets you down, remember supercomputers are still being used for scientific progress
Today, physicists use supercomputers to generate a"snapshot" of the environment inside a proton, and use mathematics to add quarks and gluons to the mix to see how they interact. These simulations are repeated thousands of times over and then averaged to predict how these elemental particles behave in the real world.
The first two phases will involve optimizing the software used to model quantum chromodynamics – the theory governing photons and neutrons – to break up the calculations into smaller chunks, and take better advantage of the even greater degrees of parallelism available on next-gen supercomputers. “A good chunk of our efforts have been trying to find communication-avoiding algorithms and to lower the amount of communication that has to come off the nodes,” he said.The team is also looking at applying machine-learning principles to parameterize the probability distributions at the heart of these simulations. According to Edwards, this has the potential to dramatically speed up simulation times and also helps to eliminate many of the bottlenecks around node-to-note communications.
