Thank you all for the information. It would appear we are stuck with 32
CPUs for the moment and, since I'm retiring at the end of next week, I
guess my replacement will have to decide how to proceed :-)
Thanks again,
Ray

Can this be modified to allow >32 CPUs?
If Christian is right (and he almost certainly is), then the only thing that
will allow you to have more than 32 CPUs is to recompile the kernel with
CONFIG_NR_CPUS set to a higher value. I just looked at one of my SLES12 test
systems, and we have CONFIG_NR_CPUS=256 specified, so I'm guessing having a lot
of headroom won't cause any problems.
