CPU: shin-compute-005: Intel(R) Xeon(R) Gold 6148 CPU @ 2.40GHz (40 cores, 80 threads), 123.3 GB of memory
CUDA: shin-compute-005: Intel(R) Xeon(R) Gold 6148 CPU @ 2.40GHz (40 cores, 80 threads), 123.3 GB of memory; Quadro RTX 6000, 23.5 GB, driver 13.5.0, CUDA runtime 13.4.0
Benchmark 0.1.0 fixes the instances, the options, Ipopt and HSL 2025.7.21.
SGM: shifted geometric mean of the solve time, with a shift of 10 s and a failure counting as 7200 s, over the problems that all solvers shown have run. SSGM: the SGM scaled so that Ipopt, or the best solver where Ipopt has not run, is 1.
