Hum, is that per CPU or the total for a machine? The reason I ask is we
have some large memory nodes (3TB of RAM) and these are quad Xeon 6138
CPU's giving a total of 80 cores in the machine...
We have not seen any problems, but if it is 64 cores per machine IBM
needs to do some scaling testing ASAP to raise the limit as 64 cores per
machine in 2019 is ridiculously low.
