4x E7-8880 v3 @ 2.30GHz (16 cores per package = 64 physical, 128 virtual cores) and 1952 GB of DDR4 RAM (2133 MHz?):
“runningtime” : 61.11619100 on a single core. Ignoring hyperthreading, that’d give about 2.09 solves per second.
i7-5820k and 32 GB of DDR4 RAM (2133 MHz):
“runningtime” : 42.83929600 on a single core. Ignoring hyperthreading, that’d give about 0.28 solves per second.
Left that 64-core machine running for the last ~1.5 hours, got 17 of the last 36 blocks. Only about 48 GB of its RAM is being used. Also I listed each package as 16 cores rather than 18, as I’m in a virtualized environment and only allocated 16 of the 18 cores of each package to the VM this is running in.
