Hi;
My question's is when I check "system info" on Quandrand Benchmark, sometime it shows 2 cord, but most of the time it show 1 cord; does anybody know why; if there's a reason, is there anyway I could set the CPU running 2 cord all the time.
I noticed this the only reason i could grasp was maybe the phone wasnt doing enough work for it to see both cores functioning at the same time when i tried antutu i think thats what its called it showed me 2 cores if i had music running in the back ground if that makes any sense, i presumed it would just show both cores like yourself
Quadrant is NOT optimized for Dual core devices. So whatever it shows doesn't matter.
You've to do nothing to run the device on two cores, it will automatically run when it needs to.

Just to be sure, disable power saving mode before running a benchmark.
This will adapt CPU frequency and number of activated cores to the system need.

You have to flash a compatible kernel to enable this feature.
Lulz Kernel or Siyah Kernel.
http://forum.xda-developers.com/showthread.php?t=1263838
Then use Tegrak's 2nd Core application from market.
https://market.android.com/details?id=com.tegrak.secondcore
With this app, you can have the cpu run in
1) Dynamic Hotplug Mode, which is the stock behavior where in second core is active only when the load is high.
2) Single core mode, where only one core is active even if load is high.
3) Dual core mode where in the two cores are always active, even at low loads.
Option 2 will give you more battery at the cost of performance.
Option 3 will give you more performance and higher benchmark scores at the cost of battery.
I downloaded 2nd core from market; however non of those option can be highlighted, I am using [email protected] #23 as my kernel.

I just got my SGS2 today and was so eager I had it rooted within 2 hours of it being placed in my hands. I was messing around in quadrant and clicked System Information..I scrolled to the CPU section and by Cores it says 1..but my friends sgs2 says 2 cores. He has the Sprint model.
Now why does it say I only have 1 core when this phone has 2?

Because sometimes depending on the service providor some details
shown are not as specific as with other service providors.
Now if your friend was on AT&T like you you noticed
this difference then it would be a different matter.
Depends on your current frequency... when mine is 500MHz or higher, Quadrant returns 2 cores... when running low frequencies, it will return value of 1 core. If you load up a few apps, then jump over to Quadrant, it will most likely show 2 cores as your CPU frequency will be higher.

The exynos cores on our phones run asynchronous - when not needed one of the cores will power down, and as soon as it is needed it will ramp up. so just as the poster above posted when the first processor throttles down the second will shut off to save power, there is no need for two processors running using battery when demand for them is low.

Not exactly depending on frequency... I don't remember the exact hotplugging heuristic.
But in general - The second core is shut off by default and only gets powered on when under load.
Note that some dual-core phones (like Atrix) always show two cores because they are unable to fully remove the second core from a system and completely shut it down to save power. (Well, I assume the Atrix - I know the Tegra in my Tab 10.1 can't hotplug the second core out/in.)
Can anybody enlighten me or point me to a thread as to why the second core only works when I have setcpu installed on my resound?
Thanks!

Second core only comes on when it's needed, and Gingerbread really wasn't designed with more than 1 core in mind. http://forum.xda-developers.com/showthread.php?t=1461875 Search is your best friend.
Be happy it does, I spent 3 days trying to figure out why my 2nd core wasnt coming online. I finally found a post about it on xda.

Even then, when it's needed, and using ICS it doesn't turn on unless you're using SetCPU.
If you want to enable it manually do this from either "adb shell" or from the console on your phone:
Here's the full command string:
su
echo 1 > /sys/devices/system/cpu/cpu1/online
I know benchmarks don't really mean that much but with my second core enabled and both OC'd to 1.7 GHz while on Newt's Senseless ICS, my scores destroy the GNex and anything I was getting before!
Antutu: 6,929
Quadrant: 3,594

How is the battery life after 2nd core is activated ?
Thanks
I dont see a difference, as each core shares responsibility. So instead of one core being at 1.7ghz each core an be at 850mhz. Although sometimes the one core will max out without intiating the 2nd core.

Pretty crappy, but then again I have it at 75% brightness and the performance gov set to 1.7 GHz and 192 MHz with the screen off. My phone was fully charged at 1 PM, and it's currently at 45% using the standard battery. I only ran a few benchmarks with antutu and quadrant and a few other less intensive things. Looking at the battery info 78% of my battery usage is from the screen.
Try the AnthraX kernal in the development section. I believe its clocked at 1.51 to force the second core to turn on.

I have it up and running, so far so good.
I just tried it and it will boot up for me but the touchscreen won't work. I'm using Newt's Senseless.
System Tuner Pro will allow you to force both cores online. Also it overclocks and undervolts aswell.

It currently only works with GB roms. Ignore me if Newt's Senseless is one, I thought it was ICS.
It is an ICS ROM I saw some people had it working with ineffibilis so I decided to give it a shot for the hell of it to see if it would work.
You dont need to force the 2nd core on, it will kick on. If you arent using setcpu that could be an issue. Antutu doesnt work. Also use cpu usage monitor and you can see both cores work.
Sent from my ADR6425LVW
Just a note i read on one of the kernels they stopped forcing the second core on because it caused issues. In the end i truly believe it would be unwise to do so. Let the cpu do its thing. Im on bamf 1.02 and my second core kicks on when it needs to.

so it's wise to use setcpu over antutu? I'll have to try again since I usually get freezing using setcpu with all kernels. no oc nor uv. might just be a bad combo between undeclock and current governor
I just tried enabling both cores with system tuner pro and it worked but evening started going a little jerky. I disabled it again and everything was fine again.

Yeah forcing 2nd core online is a bad idea. Using setcpu, oc max 1.7 min 192. No profiles no uv. Using cpu usage monitor to view cpu usage.

I got my awesome shiny new XPS yesterday. I am very pleased with it.
But today i began looking at tweaking and customizing it.....but i have noticed something quite disturbing.....
The phone doesnt seem to have both cores active!!!
When i check in "SystemPanel" it shows the list of 2 cores but only shows 1 as active......so i checked with "CPU Usage Monitor" and that lists the phone as only having 1 core?!?!
Is there a geek out there that can help me with this issue?
Is it me being a twot...or is there something that i dont know about?
From what i can tell the second core doesnt come on during gaming or benching.....
Im lost

Could you run benchmark quadrant and post your score here with a screen shot?
That app shows the same here, but linpack shows me 55mflop for single thread and 84 for milti. My quadrant is 3280

You wont see the second core active unless it's needed, when you're looking at the usage windows the mobile doesn't need to use the second core.
Run something like titanium backup as it's a background process at the same time as the usage monitor app.

Thats what he said.
I have heard a couple of times around the forum that second core is actually underlocked heavily and doesn't kick in even if needed. Is that true?

Nope. Where did you hear this rubbish?
2nd Core does work!!!
I had tested on 2nd Core by using Quadrant Standard...
(I installed SystemPanel Lite to check for CPU)
While the full benchmark is running, long press the home button and then open SystemPanel Lite,
I can see both cores are running fully...
This shows that the 2nd core does work!!!
Gingerbread does not fully utilize both cores. Some apps do. Honeycomb does have dual core support and ics should have proper multicore support.
it's like windows XP and windows vista/7
XP wasn't designed for dualcores but vista and 7 are.
Yeah like the other guys said, people go on about quad cores and stuff, some phones including the Xperia S aren't even using dual cores let alone quad cores unless they are running ICS, when ICS hits then we will.

Hello everybody,
My friend and me(we have s-on and ics stock last version) when we tried quandrant we usually get 2700 scores.But he told me yesterday he tried different way that he added one line in "buid.prop" and he got 3600 marks quandrant scores
When he opened quandtrant benchmark system information he saw just 1 core is writing.He thought we should see 2 cores because we have 2 cores and ics (even leak)version.
So he wants to added in build.prop ''persist.sys.ui.hw=1'' and he wiped dalvic cache and cache and fix permission then restart system.He checked quandtrant standarts and he saw that 2 cores were writing there and immediately he got run full benchmark and got 3600-3500 marks.So we think that the reason of 2 cores.
But when he checked after 20 min later it was writing again 1 core in quantrand system information.It s chancing by itself.we can get more performans? is it possible to keep it?
I remember some guys talking about cores and they told just check antutu you gonna see 2 cores.Second core works when need it.But my friend added ''persist.sys.ui.hw=1" this line in build.prop and maybe he made 2 cores active So what do you think about it?Maybe somebody try this way and share results with us?

The first few pages of this threadhttp://forum.xda-developers.com/showthread.php?t=1616669 talked extensively about dual-core and quadrant scores, and I would say by page 10 it was agreed upon that quadrant really just sucks. Go check it out, maybe that will shine some light for you..
I remember reading about how ICS improved dual core support, and I could have sworn it was on developer.android.com but I can't find the article that explains it now(and too many results to sift thru) - but basically the tweak "persist.sys.ui.hw=1" would have been found in gingerbread roms, because it DID increase performance, however with the way ICS handles the threading of dual-core+ processors that shouldn't do anything.
And before someone comes in here and says this in a not-as-nice way, be careful using quadrant benchmark as a tool- if ONE little detail is different, you will get TOTALLY different results! A different launcher, a different setting, or even having different background processes or having recently run a different app will change the score TOTALLY. Run it 10 times, chances are it will put out wildly different numbers - now go run 10 apps, then go back into quadrant and run it 10 more time - again, wildly different numbers, no consistency.
Besides, all that REALLY matters is your experience - if your score goes up a thousand(consistently somehow) but it doesn't work noticeably smoother, faster, or better- then what does your score matter? You could add 2 more cores, another gig of ram, better gpu - but if you can't NOTICE a difference then what would the point be?
It is easy to find why people added 'persist.sys.ui.hw=1' to gingerbread, but I can't find ANY documentation/posts that give a real reason to add it in an ICS build.. hope this answers your question.
And if anyone can find the link to googles explanation on how ice cream sandwich handles multi-core cpus compared to gingerbread can you PM it to me?
Thanks my friend your answer.Just ı got that if use quandrant benchmark test when ı check system information if ı see 2 core ı get 3500 marks but if ı see just 1 core system informatin ı can get 2700 marks.
So it depents on cores ı see.Its fault of benchmark app or our phone works one core just when need it use second core?
Hello,
easy question: how can I check if all cores are working fine?
If I check with System tuner or other apps I always find 1 or 2 cores online, but I have never seen 3rd and 4th cores working.
How can I check to see if all the 4 cores run correctly when needed?

The app is called "Quick System Info" and also shows real time stats of any core in notification bar.
Do something CPU intensive, THEN look in system panel.
All the cores will be working fine, don't worry.

Even Games may sometimes not be enough to make pegasusq wake up all cores since the others are not loaded enough.
I think that's a good demonstration of how awesome the Exynos is =) (Actually games usually rely more on the GPU than the CPU)
