A research team from the University of Tokyo in Japan has been named a finalist for the ACM Gordon Bell Prize for a record-setting earthquake wave simulation created in collaboration with the Oak Ridge National Laboratory and the Swiss National Supercomputing Center.
The team accelerated the model using artificial intelligence (AI) and transprecision computing, and for the first time accounted for ground tremors paired with underground and above-ground urban structures at super-high resolution.
Transprecision calculations reduce data transfer rates and expedite computing by storing, transferring, and computing only a fraction of the digits that standard double precision calculations utilize.
The researchers performed their largest simulation on the IBM AC922 Summit, the world's most powerful supercomputer, using 24,576 of its graphical processing units to enable a 25.3-fold acceleration compared to methods that employed neither AI nor transprecision computing.
