These two methods of calculating arithmetic are used for different applications in computational science, and double precision is considered the ultimate standard. On the other hand, Summit’s HPL-AI performance scores its mixed-precision compute capabilities. When operational in 2022, Frontier is expected to deliver more than 1.5 exaflops of double-precision performance. With its submitted speed of 1.15 exaflops, or a billion billion (1018) floating point operations per second, has Summit somehow jumped into the exascale era of supercomputing ahead of the OLCF’s upcoming Frontier system? No. But it also took second place in a relatively new benchmark test apart from the main competition: High-Performance Linpack–Accelerator Introspection (HPL-AI). JAt ISC High Performance 2021, a European virtual conference for high-performance computing (HPC), the Oak Ridge Leadership Computing Facility’s (OLCF’s) Summit was ranked as the world’s second-fastest supercomputer in the 57th TOP500 list.
