The solvers were run on an Intel Xeon Gold 6230 2.10GHz (40 cores, 385GB) on the discrete non-convex problems (160 total) with not only binary variables from QPLIB. Times given are elapsed times in seconds. All problems are solved GLOBALLY. Time limit 3hrs, 8 threads. Only those instances are shown for which at least one solver succeeded. Shifted and scaled geometric mean of runtimes:
