He (typically) is running WCG on 4 systems, each system having a 14 core/28 thread Xeon, and I'm sure he has been letting his new pair of 16 thread Ryzen systems have some fun too on occasion.
Edit: It would sure be nice to have someone else pay that electric bill, but these are his personal, at home systems.
Edit 2: Here is his signature. He's nuttier than a squirrel turd, and I'm jealous :
