[brlcad-tracker] [Google Code-in 2012] New comment on Investigate performance of setting thread affinity

Hi,


Sean has left the following comment at Investigate performance of setting  
thread affinity

hot diggity


So Skriptkid, a little encouragement perhaps. I applied your patch and did  
a real quick-fix for the various build issues I alluded to (which you  
should still fix properly). I then tested the performance impact on a real  
compute system.

On a 64-processor POWER7 beast, I'm seeing our *debug* benchmark results  
going from around 44000 VGRs to around 67000 VGRs. That's more than a 50%  
performance increase, but wait, it gets better...

Our *optimized* production benchmark results increase from around 121000  
VGRs to 185000 VGRs!

That. Is. Awesome.

Your patch is going to make some big attention in our next major release.  
I'll also be adding extra tasks to implement thread affinity for BSD and  
Windows.


Greetings,
