So I installed system tuner from playstore and I'm looking at both cpu's and I noticed CPU 0 is running 100% of the time and CPU 1 is offline 99% of the time? I have this app on my galaxy nexus and CPU 0 and 1 would be online 100% of the time, so any of u guys wanna download that app and post ur results?? Or dose someone out there that nos more about the chips in this phone care to " school " me? ///my phone is rooted

It's the way that all dual core phones work to save battery. When using the phone heavily, both should kick on. While not doing anything or not processor heavy, just one core would run.

Correct.
CPU1 is rarely ever used. This is to conserve battery. It gets turned on/used only when there is a demand for extra processing power.
But some custom ROM/kernel combo's will change it so that CPU1 is used 100% of the time. I'd guess you had a custom kernel on your Nexus?

Thank u guys, This is what I figured, but I've never had stock rom and kernel on any of my other dual core phones this is longest I've ever had stock rom and kernel (4 days ; p) and had no idea CPU 1 is never really used cause yes most kernels take advantage of both, I turned on CPU 1 with the app but I don't think its working right, phone seems faster but I need run some tests ....thanks agn

So there is something that I'm trying to figure out.
I am currently running Virus' Infected Eternity 1.5 r31 and using RCMIX 3D v11 kernel. Regardless whether it is overclocked (which I usually run 1.51 ghz) or standard and regardless of whether running a govenor like lagfree or a SetCPU one like performance, when I open the app SystemPanel Monitor it shows only one core running. According to Freeza's thread, his kernel has "dual cores active" and it shows SystemPanel Monitor with two cores running. I switched to Freeza's kernel with Eternity ROM and and checked again and it only shows one core running.
So what I'm trying to figure out is, is this ROM related or am I really only running one core and the other is not used, or otherwise how do I know if both cores are running?
My phone with Eternity ROM is smooth and runs games and videos well with no choppiness so I think it is ok. I just want to know how we can know that both cores are running.
I would also like an answer to this question..
Its because of SetCPU if you remove it and install say CPU Master your second core will be activated.
I thought the latest SetCPU was setup for dual cores?

This Worked!! Thanks cruecu. Seems as though if the demand is not there the second core is idle for these particular govenors.
So this begs the questions.....Which is better (for speed and/or battery life), running mostly one core at full speed and then the second when only necessary, or running both simultaneously at half speed? I've seen some discussion on this but it's not real clear.

I'm not sure one has been proven more effective. I personally don't want both cores running all the time...I don't notice a speed increase since clock speed is still the same. Not sure it matters either way, but I will only run a rom that uses second core only when needed

For the most part I agree with this statement. The reality is the device feels faster and will benchmark better. The better benchmarking is what sold a lot of people. The question still remains is if the device finishes processing the data in half the time is it using more battery? I personally have not noticed a drain on the battery and it may even be a little better. If you let the device decide when to use the second core it may never use it.
Also on some ROMs like my Fresh ROM you can just delete the dual core script in the init.d folder and it will return to single core mode.
Ok, I have side questions that pertains to this topic.
If we can enable the second core in init.d when the phone boots, AND it actually does useful work then HTC would have had to have put effort into supporting that in their kernel because ASOP Gingerbread does not naively support dual core, right? So that makes me wonder why HTC shipped the 3D with dual core inactive! Unless I'm flat out wrong somewhere HTC must have had a reason, and the only things I can think of are race conditions and battery life.

Our CPU was not designed to run this way (asynchronous CPU). That is why it is not active all the time. Now Nvidia Tegra processors (synchronous CPU) are designed to run dual core all the time. That also seem to produce better benchmarks.
HTC kernel is designed to run the way the processor was designed. HTC would not override the CPU specs like we would just to make the benchmark better. The theory is that asynchronous CPU would have better battery life. Reality is most XDA members only care about benchmarks so they can show their friends.

While I agree with you in principle, I do have both cores active at all times. I have not noticed any difference in battery life. Yet I have noticed a difference of quite a bit less lag while loading applications and flipping through screens than when CPU1 is idle.
Does it really matter in the long run daily use? Not really. It's a fun tweak and I learned something new by utilizing it.
I did not get a truly noticeable difference in benchmark though.

Ok so im rooted and overclocked and was using setcpu then decided i wanna try something different so i tried system tuner! When i checked the cpu it said that one of the processors are off line! Then i pressed the info button and sure enough it says only reading one! So i went through the settings and found force both cores online!
Since then i have no lag and virtually no checkerboarding on the web! Anyway i was just wondering if im the only one who noticed this and maybe it could help those who say that they are still getting lag on they're roms using dag's kernel!
Also i hope devs will notice this thread since i can't post there yet and take advantage of this how ever they can!
Now don't quote me on this but most likely the second core only turns on for processor intensive activities such as high graphics games or multiple programs running at once. I do find it hard to believe that it would be totally disabled. Most likely this is done to conserve battery.

Okay if this really is the case I could also see at&t disabling the second core totally to save battery because of lte but i guess it will take a dev that has more experience with how qualcomm's multicore cpus work in android. report back with differences in battery life like how much faster does it drain now that both cores are forced on.
if you want both cores on click on boot settings and enable force all cpus online. that heats up your phone and eats more battery though+I do not see any benefits doing that.

Same, but having a better processor helps. Like exynos. I bet once we update to ics if it ever happens, the differences will be only minor between processors, as it runs so nice.

Not entirely true.. the Galaxy Nexus has a kernel governor that turns one core off when the SCREEN IS OFF, but not when the phone is being used. Multiple kernel creators have since implemented this into their kernels. It is called "hot plugging" and it just turns CPU 1 offline when the screen is off and turns it back on when the screen is on

Just checked mine, rooted and OC with DaG's 0.1 version (first version). When I looked, it said the second CPU was offline. Changed it to online, we'll see how that impacts battery life.
How much of an advantage is smartassv2 anyway?
I just tried this with system tuner and both cpus were working but wone was of and on and zero was always on.
I am running stock rooted. If you just sit yhere and watch it you will see tje sevond core fires and shuts down alot.

I guess jury is still out or is this a YMMV kind of thing?
I installed system runner and watched the cpus. One was on and the other kicked in periodically
Mine said it was offline as well. Forced it on and am not noticing any difference in speed or temp.

As far as I know yes you must have super user permission to alter such system activities
I don't know why everyone is in such a rush to force the second core online, it turns on and off when it needs to.

No, they don't. If you want to enable dual core support just delete mpdesicion from System and edit a file(i don't remember the name). Also, after you booted on the ROM you can download Quadrant Advanced and make a custom Bench, select CPU and you will see if both cores are availables.

performance on 2.3.4 GB will not increase by having both cores on. this is a common misconception about dual core on that platform. the software is not programmed to utilize synchronized multi thread - they handle tasks independently. you are wasting battery, with no performance increase, when using dual core on gingerbread......

OK I'm still learning Android.
What has been sort of puzzling to me now suddenly makes sense.
In most of the ICS threads I've been following, people are raving about how good the battery life is. People saying I watched 30 movies, made 118 phone calls and my battery is still 97% charged. Ok I'm exaggerating but anyhow making some unbelievable claims about battery life in ICS.
From what I've reading here at XDA and other forums, ICS taps more resources and uses more memory than GB did to run apps. So why so much better battery life?
Could it be that ICS not being dual core support unless you make it so is only using half the power of the CPU? Sort of like putting a 2 bbl carburetor on a Corvette engine where a 4 bbl would unleash the beast but use more gas?

Latest ics releases have finally fixed the cpu1 always online. System tuner pro can show you current states on CPU states. Again system tuner pro can also FORCE dual core CPU always on.
Better battery life comes from the 3.0 kernel which has better power management, amongst other things.
The second CPU kicks on as needed unless you force it always on, which drains more battery.

So it would seem by getting system tuner Pro you could turn this feature on and off like a switch.
When you want both cores running for maximum performance just turn it on in system tuner Pro, then turn if off when your done with it?
That would be alot better and easier than editing file commands.

Something like that. System tuner pro can force dual core by init.d script or after boot completed. It has boot settings, which you choose. A reboot is needed after changing I believe.

Interesting. Well its fun learning all this.
Maybe down the road as things get fully developed someone will come out with an app or widget. One where you just click it and turns on both cores on the fly. Call it TurboThruster or something like that. The icon could be flames shooting out of a tailpipe.
As phones develop they'll have quad core and more and more..........

I was looking stuff up on that today. The highest I could find documented was 1900 on the cpu and 800 on the gpu.
For everyday usage, overclocking is useless, even for gaming. Undervolting can be beneficial, but from what I've seen, the latest processors get approximately the same battery life on stock voltage as they do undervolted.

I just like to play around with different kernels but the kernel I was using def made the device snappier and I had some killer benchmarks! But you are right though! Custom kernels on this device is not really necessary...
I plan on building a custom kernel then, hopefully tomorrow night or possibly Saturday. I do have some plans to improve it, but nothing related to the CPU or GPU going faster, just having other stuff operate better and getting rid of anything not needed.

HA. My TBolt stayed stable at 1200, but ANYTHING higher than that and it would crap out on me.
I could run my bolt stable at 1700 all day. Kept it at 14 for a month no issues. Stayed at 13 the rest of the time. Course at 17 it was like it was running on a watch battery with the amount of time it would last. Lol
Eh I ran 1.6Ghz on my Thunderbolt 24/7 and with the 2750mah battery it lasted me days.
On a phone like that there was a significant improvement to the end user that justified the overclock. Now on the Note 2 I'd expect there to be very few who would want an overclock at all. I am part of the very few however. I play a lot of emulators on my phone and for N64 and Playstation I need all the raw CPU power I can get. Yep, even on this beast of a phone I still get some lag and stuttering on those emulators. The reason being is the same as PC gaming. AMD thinks that by adding more and more cores to their processors they can win the performance arena. Unfortunately they are wrong. Intel has the right idea, 4 cores is plenty now let's improve the efficiency and performance of those specific cores.
Same goes for our phones. Quad core is the most I'd ever want in my computers, anymore is just a waste. Now let's get better architecture for the processor to maximize clock-for-clock performance. And overclocking those cores helps it in apps that don't support more than one or two cores, because the baseline performance for each core is boosted.
So yeah, can't wait for a 1.8Ghz kernel
