Igor Sfiligoi from SDSC gave this talk at the ECSS Symposium. “I have recently helped IceCube expand their resource pool by a few orders of magnitude, first to 380 PFLOP32s for a few hours and later to 170 PFLOP32s for a whole workday. In this session I will explain what was done and how, alongside an overview of why IceCube needs so much compute.”
SDSC Conducts 50,000+ GPU Cloudburst Experiment with Wisconsin IceCube Particle Astrophysics Center
November 25, 2019 by
In all, some 51,500 GPU processors were used during the approximately two-hour experiment conducted on November 16 and funded under a National Science Foundation EAGER grant. The experiment used simulations from the IceCube Neutrino Observatory, an array of some 5,160 optical sensors deep within a cubic kilometer of ice at the South Pole. In 2017, researchers at the NSF-funded observatory found the first evidence of a source of high-energy cosmic neutrinos – subatomic particles that can emerge from their sources and pass through the universe unscathed, traveling for billions of light years to Earth from some of the most extreme environments in the universe.
The Challenges of Updating Scientific Codes for New HPC Architectures
