INL Falcon

Idaho National Laboratory's SGI ICE X cluster, bought in 2014 as the successor to a machine called Fission and succeeded in turn by Lemhi (lemhi-inl). The C3+3 documentation describes the original build as 10 racks and 684 nodes of dual 12-core Xeon E5-2680v3 (16,416 cores, about 657 TFlop/s peak), later extended by four racks and re-equipped with 18-core Xeon E5-2695v4 chips for a stated 1.17 PFlop/s peak. TOP500 follows the growth: 16,416 cores at 511.24 TFlop/s Rmax in 2015, 19,200 and 25,056 cores in 2016, and 34,884 cores at 1.09 PFlop/s Rmax, 1.17 PFlop/s Rpeak and 354 kW on the November 2017 list (rank 144), which is the configuration recorded here. The documentation says 19,200 cores after the upgrade, which conflicts with TOP500's 34,884, so the tier stays reported. In April 2022 INL handed the hardware to the University of Idaho, Boise State University and Idaho State University to run collaboratively; INL's own service is recorded as ending then, the same convention used for Lemhi.
