What is the command to find out the number of cores(4 or 6 or 8) in
the Netra T2000 machine? |

Take the output of 'psrinfo|wc -l' then divide it by 4.
psrinfo|wc -l on 8 core T2000 will say '32', meaning 32 virtual
processors.
On 6 core T2000, it will say 24.
On 4 core T2000, it will say 16.
On a broken T2000, it will say something other than 16, 24, or 32. :P
One virtual processor on T2000 = one hardware thread.
Each UltraSPARC T1 (T1000, T2000) core has 4 hardware threads.
So number of virtual processors divided by 4 equals number of cores.

Ah, missed combining both args. Very nice, thank you -- that's more
elegant than doing 'psrinfo|wc -l'.
The original poster still needs to remember to divide that number by 4
on the UltraSPARC T1 (e.g. T1000, T2000) to get number of cores.
