No application really utilizes HT..!

post #1 of 17
Thread Starter 
So far I have tried :

Winrar (4.00 beta2, multi-thread option enabled)
Windows Live Movie Maker 2011

Unigine Heaven 2.1
Stone Giant benchmark
Guild Wars



Here's how i test: I use Task Manager's "set affinity" feature to limit programs firstly to only 1 thread and i'm simulatiously watching the core utilization percentage. Then i give the app another thread from the same core but the second thread of the same core is not utilized at all! interesting... then i add a thread from a different core, core #2... then voila! the thread immediately got used by the application. weird isn't it? i try the second thread from core #2? well no, again no utilization at all... this is pretty much goes same till 8th thread. If i give the app all 8 threads, only 4 of them are utilized.





as you can see each core has 2 threads but only one of them is utilized. it's like having only 4 cores, really... the HT has been useless for me so far. neither in apps for video editing and compression nor in games. programs/games utilize only 1 thread of the same core.



So my questions are: How in the world does application know this? how does it distinguish the threads or real cores? do applications need to be coded specially to take advantage of HT? I thought applications were handling all available threads as cores. why do my HT threads are never utilized?

It comes back to Windows' thread scheduler at the end of the day. Presuming the code is written to leverage many threads in the 1st place.

BTW-Folding@Home uses HT.

it is very nice actually, just not for you i guess

sell it for a 2500k if you cant take advantage of HT
post #8 of 17
lol - I know right?

Cinebench, and Vantage do too.

In fact you can bet the list of things you use your computer everyday for that will take advantage of that many threads can be counted on one hand.

Using foobar2000 to convert garbage formats like ape, tak, wv, wav, to flac -8, appears to take full advantage of HT (if you have at least 8 files to convert).

But yeah, for 95% of people and 99% programs HT is useless.

Ever render anything with kerkythea or similar rendering software? They take full advantage of all your cores/threads.
