you could probably do it for cheaper using a larger pool of preemptable instances. I think you may end up saving money buying your own blades (21x4 Intel Xeon 32-core CPUs = ~$210K, I'm assuming motherboards + power + ram is less than 3x that.) I didn't factor in AMD's 128-core Epyc processors or Xeon Phis because I don't know enough about their suitability.. do you need AVX-512 for this kind of thing?
