HP-UX Virtual Partitions Administrator Guide (includes A.05.09) (5900-2188, March 2012)

The hardware paths for the sibling pairs are
0/10 and 0/11
0/12 and 0/13
0/14 and 0/15
0/16 and 0/17
After vPars is installed, you can also use the vPars Monitor’s scan command to show hardware
paths.

CPU: Hyperthreading ON/OFF (HT ON/OFF)
Hyperthreading is a new feature supported in HP-UX 11i v3 (11.31) environments on servers with
the dual core Intel Itanium processors. It provides for executing multiple threads on a single core.
This allows multiple hardware threads to share under-utilized resources, increasing overall throughput
and performance. Throughput increases are typically achieved by making use of the idle cycles
and idle functional units that occur due to memory stalls. For more information on hyperthreading
and performance, see the white paper Dynamic Logical Processors for Hyper-Threading on HP-UX
11i v3 available on the BSC website at http://www.hp.com/go/bizsupport.
