I thought 64 cores was a limit coming from Postgres http://rhaas.blogspot.com/2012/04/did-i-say-32-cores-how-about-64.html http://rhaas.blogspot.com/2012/04/di

  I would think it is a bit higher now, as this benchmark is for a pretty old version that's not even supported anymore. In particular, I'm pretty sure that shared memory throughput is a major factor for scaling the number of cores, and there have been quite a few changes to the shared memory subsystem since then. But even then, there probably are some significant overheads that are reached before you get to the limits of single node systems that are available today.

  That’s a 10 year old restriction. At least as of Postgres 9.2 you could run more than 64 cores (though Postgres didn’t always use them effectively).
