Determining Sibling CPUs
Once you have determined that you have a dual-core system, the siblings have adjacent hardware paths. The
first core’s path ends in an even number, and its sibling’s path ends in the following (odd) number. For
example, if the ioscan output shows:
0/10 processor Processor
0/11 processor Processor
0/12 processor Processor
0/13 processor Processor
0/14 processor Processor
0/15 processor Processor
0/16 processor Processor
0/17 processor Processor
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.
