I just read a blog about someone rent an AWS hpc & run Vanitygen to get a vanity address & some of the latest 2018 performance. Assume i have some of the top supercomputer these days(Sierra, Summit, Titan,...) & to get the address 1BitcoinEater... . How many key can it generate per second, like summit specifically? How long does it take to get the address i want?
Summit supercomputer has:
9,216 POWER9 22-core CPUs
Using CPU we have total 202752 cores to run, Vanitygen automatically use all threads to calculate, on average a CPU can generate 250k keys/sec on Vanitygen. Multiply & we have about 506Gkeys/sec, this is way lower than i expected. I don't know how to calculate time to generate the key you mention though
