IBM 3850 M2/x3950 M2 (x64)
Four of E7450 @ 2.4GHz, 6 Core, 6 Logical.

Is this considered
"symmetric multiprocessing computer"
"non-uniform memory access (NUMA) computer"
"hyperthreading-enabled processors"

1)If NUMA configured, what is the number of CPUs assigned for each NUMA node. How can be find this in the system?
2)What is the number of physical processors in the above setup?  
3)What is the number of physical processors per NUMA node in the above setup?

I need to do some more digging, or somebody else can fill in the blanks (and correct my boo-boos), but so far...

>> "symmetric multiprocessing computer"

not sure, but I'm going with yes.

>> "non-uniform memory access (NUMA) computer"

not sure, but I'm going with yes.

>> "hyperthreading-enabled processors"

definitely not.

>> 1) If NUMA configured, what is the number of CPUs assigned for each NUMA node. How can  be find this in the system?

Not a "hard" number, as far as I know.  Usually a variable that you can set. In the BIOS?

>> 2) What is the number of physical processors in the above setup?  

Depends on your definition of physical processors.  4 physical cpus, with 6 cores each, for a total of 24 discrete processors.

>> 3) What is the number of physical processors per NUMA node in the above setup?

see #1

Here's a .PDF spec sheet on the 3850 (might be a little "dated", as it doesn't mention the E7450 cpu as being supported).
