Wait for quite a while (more than 1 hour).cd benchmarks_2017/linux/mkl/benchmarks/linpack.Sunway TaihuLight: 93 * 10^15 FLOPS ( source, record holder of 2016).GTX Titan Black GPU: 5.1 * 10^12 FLOPS ( source).Still I do wonder why you care, what you are using it for? If you just want a meaningless number, your systems bogomips is still right there in dmesg. might be an easier way to install a flops benchmark. And of course, your SSE (etc) units can add floating point performance too. The next issue is memory performance, there is a reason the last classic CRAY had 31 memory banks, ultimately CPU performance is limited by how fast you can read and write to memory, so what level of caching does your problem fit in? Linpack was a real benchmark once, now it fits in cache (L2 if not L1) and is more of a pure theoretical CPU benchmark. Some floating point ops take a long time (divide, for starters), add and multiply are typically quick (one per fp unit per clock). The question is what do you mean by flops? If all you care about is how many of the simplest floating point operations per clock, it is probably 3x your clock speed, but that is about as meaningless as bogomips.
