[slurm-users] How to turn off core specialization?

What's even stranger is that I can change CoreSpecCount to any other number (2, 3, whatever), restart the daemons, and the change is made. But if I try to set it to 0, nothing happens. It's like there's a setting somewhere that is forcing CoreSpecCount to be >0. But I have no idea what that could be.

Yes, I have done that on every node, but it still shows one specialized core.

I tried "scontrol reconfigure", but it also had no effect.
