Dual cores - HTC EVO 3D

Is there an app or one being worked on that will eun both cores at the same time? Thanks guys for ure help

I put out a modified kernel that enables the second core all of the time. You just can't use SetCPU or it will revert back to one core active/second core active on demand.

I appreciate it brother and you have been thanked. I see you said not to use Setcpu with this so is there another over clocking agent I can use? I want my phone as fast as can be and absolutely hate the fact it is dual core and does not use its full potential against the other duals out there.
Thanks again brother, so many **** post going around it is nice to see someone give a straight answer with no bs

I've been researching this myself, and the two best candidates that don't mess with the second care are: CPU Master/CPU Tuner.
I prefer CPU Tuner, but for some reason, it doesn't work correctly with my phone (it doesn't detect governors). Maybe it will with yours. 2.7.6 is the version that did work but it also had an issue where it would scale the CPU up to its max when you launch the app, which would cause my phone to reboot since it doesn't handle 1.836 GHz very well. It's up to 2.7.8 now and I've been exchanging emails with the dev on the issue. Hopefully it is resolved soon because it is a very very good app.
CPU Master is a bit more lightweight and a little less frills but it seems to do the job quite well most of the time. However, sometimes it does get confused on what profiles it should be using.
To be honest, you can pretty much use any kernel and with a simple script, enable the second core to run all the time. It doesn't necessarily need to be mine (since it's simply a modified stock kernel and doesn't support overclocking).
Once you settle on a kernel, I can provide the script or show you what needs to be done to enable the second core all the time.

I prefer to run bcb blend. Can u please provide me the script and a walkthrough to get this going? Thanks so much for your help bud

I wanted this as well, but I talked to Cayniarb he says it makes the phone worse. Then smokin tried to enable it for are aosp roms and he said it gave alot of issues and bugs. Honestly when I was using the dual core mod on Showdowns' rom, I didn't have a problem, with battery life or anything. Something may come up again in the future. I just want this beast to run like it should.

There are a number of ways to go about doing this:
ramdisk
init.d
init.post_boot.sh
But, the easiest fastest way to get this accomplished is to either upload and post your init.post_boot.sh file, which is located in /system/etc/, OR edit it manually yourself.
There are other ways but this file already exists, and has most of what you need in it and it gets executed at boot anyway.
Take note of the permissions set for this file, because they will need to be set back if you choose to edit outside of Android. You can also edit the file with Android's file editor if you use Root Explorer.
If you choose to edit it yourself and outside of Android, you will need to open the file with Notepad++ (Or whatever qualified editor you use) and add this in anywhere before the line "chown system /sys/devices/system/cpu/cpu0/online"
echo "1" > /sys/devices/system/cpu/cpu1/online
chmod 0444 /sys/devices/system/cpu/cpu1/online
echo "ondemand" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
chmod 0644 /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
What this does is set the second core's online state to 1 (enabled) and the second line sets this value as read-only, so that the system can't disable its online state when it feels the second core is no longer needed. The third line sets the governor, and I assume you can use any governor that's available in the kernel. However, I'm not sure if both cores can have separate governors. Changing one may change the other. I haven't tested this myself, but sampling frequency and up-threshold works like this, so I assume governors may as well. The last line, if it has anything in common with the third, sets the governor so that you may infact change it with CPU Tuner (since it has the ability to control the second core as well as the first). This line may be obsolete and was only added in as a fail safe.
While you're in there, you can tune your cores even more (assuming you don't use anything like virtuous OC, CPU Tuner, ETC) and set the min and max values by adding this (there should already be something like this for the first core so you can go ahead and add this below that):
echo 192000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo 192000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq
echo 594000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
As a way to conserve battery life, I set the second core to run at half its max (stock kernel), This works fantastically for CPU Master, which only controls the first core, as you can have all your profiles set, without messing with the second core. (I've found that you can run the first core at 192MHz with the screen off/low battery while still maintaining minimal lag by setting the second core's max to 594MHz!)
Once you've edited the file, you can go ahead and push it back to your device (assuming you've edited it outside of android) and set the permissions back to what they were and reboot.
As always, if any of this is overwhelming, I'll be happy to edit the file for you.
To check whether or not your edits were successful, you can navigate with root explorer to /sys/devices/system/cpu1 and look for "online" which should have permissions of r--r--r-- You can view the file and see if "1" is in there, indicating that the second core is active. You can also use SystemPanel to check your CPU activity, which should show both cores active. As a legend, a grey pie chart means the second core isn't active, but they should both be green and actively being used.
Good luck!

What about for aosp, I got kind of lost.
Edit: I PM'd freeza and he was a big help.
should be the same way, but if you don't have the file, you can create a init.d script
look in system/etc/init.d if there are any scripts there take one open it in notepadd++ delete all but the first line and insert the dual core line in. Then save the file as something different and push back to phone
