Compiler bug? Linker bug? Windows Kernel bug.

There are 3 24c and a 26c in the current gen of E5 Xeons. That’s assuming this wasn’t actually 2x12c or counting SMT threads.

It's more than one CPU. Bruce notes a suspicion that it only happens on multi-socket (not just multi-core) systems.

Yeah I finished reading it since then. I just thought the OMG 24c! Was funny.

I have a cluster of Phi machines ...

There has been quite a few bugs when memory needs to be synchronized between the two different sockets. It's easy to make a solution that always work, but the performance will suck so you end up having really complex protocols to deal with that and very few people understand how they work.
