Using both cores?

i have an early 2008 MBP, obviously they have 1 processor and 2 cores, what program can i get that shows that an application is using both cores? or do they always use all cores? and just (if i had multiple processors) only use the amount of processors they were designed to use?
thanks for reading

Activity is generally distributed across both cores (different 'threads' running on each core). Install iStat Menus - that can show a graphic in your menu bar with 'thermometer' or history graphs showing the two cores separately.

Logic 8 seems not be using both cores??

I've been a lot of System Overload messages so I started monitoring the CPU usage and I've noticed that Logic is only using one core. When that maxes out I get the message. I've done all the things I should be doing (freezing tracks, raising the I/O buffer size etc...) but I dont seem to be getting both cores...any thoughts?
Here's my system:
Dual 2GHz G5 w/6GB RAM, 10.5.8.

Hi,
Logic distributes different "tasks" to both CPU's. Usually, one Channelstrip goes to one CPU. Logic can't split one Channelstrip to go to different CPU's.
Solution:
If you have a Channelstrip overloaded with plugins, set the channelstrip's output to a BUS. Use the resulting AUX channelstrip to distribute the plugin chain over both the main and the AUX channelstrip.
Signal flow: Main channelstrip -> AUX channelstrip -> Out 1-2
Logic can and usually will distribute the CPU power to both strips.
Another thing: If you are not using a software instrument, switch to an empty audio track in the arrange window while playing back your project. Active (armed) software tracks are using more CPU ressources because Logic waits for your live MIDI input.

Quicktime X only uses one core on a C2D

On my mac mini C2D activity monitor shows that quicktime X refuses to use more then one core which makes hd movies look very laggy and bad. What can I do to make it use both cores?

QuickTime itself limits to a single processor/core in most cases.
Worst is that quicktime is slow to render movies.
I hope Apple will rewrite quicktime so it supports Open CL and Grand Central Dispatch.

QT Pro nor iSquint will export using both CPUs - MacBook Pro

Hello!
I've got a few videos (of various codecs) that I want to export for my iPod, at the high-res 640x480 level. Because I want more control over export settings than iTunes gives, I usually export with Quicktime Pro, or sometimes iSquint, depending on the quality I want and the codecs used.
Exporting takes a lot of time - as it does on any computer. Unfortunately, both Quicktime and iSquint seem to refuse to export using both CPU cores in my 2.2 Ghz MacBook Pro. They both suck down the entire power of one core, but the other sits idle. This greatly increases the export time, which is annoying when I've got a lot of videos to convert.
Oddly enough, when I tried exporting said source movies to a DVD via iDVD, it used both cores. In other words, QT is actually capable of using 2 cores to export videos in iDVD, but not via QT Pro itself - very very odd.
Is this a "feature" of the program - that is, QT Pro does not support dual-core encoding except through other programs - or some bug? Since iSquint does the same thing, I'm fairly sure the problem does not actually lie with Quicktime as iSquint uses the FFmpeg codecs to convert videos.
Any ideas what the problem is, and how to work around it? If it's a bug in the software, I can reinstall said application.

The "grey curtain" indicates a kernal panic. KPs are usually the result of hardware based problems or unrecoverable software issues that are system wide. I say system wide because OSX is designed to contain a balky program and will allow you to kill the program without affecting the OS.
Unplug all external devices except the keyboard and mouse and try it.
Does it work reliably?
• If so, start connecting your externals one by one until you find the one that causes issues.
• if not, you can try a full erase and reinstall of the software and OS. This may help.
If not, it is likely that you have a hardware issue that will need to be addressed by a certified repair technician.
good luck.

World of Warcraft now using two cores?

Hello everyone,
I've been running WoW on my quad box for a while now. And every time I would play, it would only use up one core. I just noticed today that it's using two cores. Has anyone else noticed the same? I'm wondering if it's actually using both cores for game play, or if this is just a bug. I'm running the latest WoW with the BC expansion and wine-0.9.41 since 0.9.44-1 doesn't play right with WoW.

Google search for 'multicore world of warcraft' and you will get a happy surprise.

I have 12 core with Quatro 4000 and 5770, I want to use dual monitor setup, monitors are NEC with Spectraview-II. How do I connect? 4000 only has 1 Display Port and 1 DVI. 5770 has 2 of each, if I use both 5770 Display Ports, does the 4000 contribute?

I just bought a 12 core with Quatro 4000 and 5770, I want to use dual monitor setup, monitors are NEC with Spectraview-II. How do I connect? 4000 only has 1 Display Port and 1 DVI. 5770 has 2 of each, if I use both 5770 Display Ports, does the 4000 contribute any work at all? I read where on a PC they would work together, but on a MAC they do not.
I read that Display Port has higher band width than DVI, NEC monitors for best performance they recommend using DIsplay Port.
When I was setting this up I looked at a Nvidia Quadro 4000, unfortunately it was for PC, it had 2 Display Ports, in the Mac version they reduce it to one. I did not think there could be a difference.
Mainly want to use it for CS6 and LR4.
How to proceed???
I do not want to use the Quadro 4000 for both, that would not optimize both monitors, one DP and 1 DVI. Using just the 5770 would work but I do not think the 4000 would be doing anything, and the 5770 has been replaced by the 5870.more bandwidth.
Any ideas, I am a Mac newbie, have not ever tried a Mac Pro, just bought off ebay and now I have these problems.
As a last resort I could sell both and get a 5870. That would work, I'm sure of that, it's just that I wanted the better graphics card.
Thanks,
Bill

The Hatter,
I am a novice at Mac so I read all I can. From what I understand the NEC monitors I bought require Display Port for their maximum performance. The GTX 680 only has DVI outputs. Difference from what I understand is larger bandwidth with the DP.
You said I have the 4000 for CUDA. I am not all that familiar with CUDA and when I do read about it I do not understand it.
A concern I have is, that if I connect the 2 high end NEC monitors via the 5770, using it's 2 Display Ports I would have nothing connected to the 4000. Is the 4000 doing anything with nothing connected? I read where in a PC system the 2 cards would interact but in a Mac system they do not.
Bottom line, as I see it, the 4000 will not be useful at all to me, since I want a dual monitor set-up.
So far the 5870 seems the best choice, higher band width than the 5770, and it has 2 Display Ports to optimize the NEC monitors.
I'm not sure how fine I am splitting hairs, nor do I know how important those hairs are. I am just trying to set up a really fast reliable system that will mainly be used for CS6 and LR4. Those NEC monitors are supposed to be top notch.

Can't I stop the HOG Flash from Firefox? I use FlashBlock but a constant fight. Often both cores maxed at 100%,laptop very slow until I kill Flash in Tsk Mangr

Flash is the problem. It often maxes both cores of my dual core processor and brings processing virtually to a halt.
Originally, I killed flash in Task Manager whenever i heard my fan come on and also noticed slow system response. This was very distracting and took a lot of time.
Then I installed FlashBlock, but it doesn't stop Flash unless you tell it for each and every website.
When reading news, and opening a link, I will hear the fan start, so i click the block button/icon in Firefox to block the site from using flash. Some sites don't launch with the FlashBlock icon. I have to use the manual kill option for them. This extremely frustrating. I understand why Steve Jobs hated Flash.
I don't like Apple's money-sucking wallet-leach behavior, so I use WinTel and live with the frustrations of which this is the biggest. HTML5 supposedly is the solution, but site builders use flash.
FireFox needs a flash control switch built in the browser to give control of Flash - block/ask, etc. functionality.

By the way, Firefox does have a Click-to-Play feature you can use for Flash. That will delay Flash from starting on a page until you approve it. However, the approval is per site, I believe, so you may need an add-on to control it per page.
To set "Ask to Activate", open the Add-ons page using either:
* Ctrl+Shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Plugins. Look for "Shockwave Flash" and change "Always Activate" to "Ask to Activate".
When you visit a site that wants to use the Flash, you should see a notification icon in the address bar and one of the following: a link in a black rectangle in the page or an infobar sliding down between the toolbar area and the page.
Not a solution, but hopefully will help a bit.

Using both CPU cores on Zynq?

Hi,
Has anyone tried to use both cpu cores of zynq?
I did not find any example from Xilinx, only related information
in "Zynq-7000 EPP Technical Reference Manual UG585 (v1.2)".
It says that cpu0 must do these two things:
1. Write the address of the application for CPU1 to 0xFFFFFFF0.
2. Execute the SEV instruction to cause CPU1 to wake up and
jump to the application.
Found a "dual cpu demo" example on ARM web-site:
http://www.arm.com/files/pdf/ZC702_DS5_2.pdf
However, the attached source code doesn't do any of the
above two actions. How can the second cpu start then?
Regards,
Pramod Ranade

Thank you j, for the suggestions.
I was basically trying with baremetal/baremetal.
First I used "hello world" example for CPU0, it
works fine. Then I added another "hello world",
but now for CPU1. Then I edited it's main() and
removed the initialization part and also the
printf("hello world"). Instead, I simply declare
a pointer to some memory location. And in an
infinite loop, I keep incrementing the value
pointed by that pointer.
The "hello world0" on the other hand has been
modified to write start address of the "hello world1"
to location 0xFFFFFFF0 and then a simple "SEV".
Then the program reads the same memory
location (which is being incremented by CPU1)
and prints it's value to UART. I was expecting that
the value will be seen increasing...but I see it
constant.
For the shared memory location, I tried 0x00700000
which is in DDR RAM. I also tried 0xFFFFE000 which
is in OCM. Neither worked...
I suspect, CPU0 needs to something more than just
writing CPU1 start address to 0xFFFFFFF0 and then
issuing a SEV. But I could not find any more information.
Nor can I find any example that uses both CPU cores.

Pramod Ranade

How do I use 2 Core Audio devices at the same time in Logic w/out switching

Hello, I use the Aardvark Direct Mix usb3 as my audio interface for mic and guitar. I just upgraded to Logic Pro 7 today and was hoping someone could tell me how I could use the Built-in Audio Core Audio driver along with the Direct Mix USB Core Audio Driver at the same time without having to switch Core Audio Driver's and than rebooting Logic. It is very frustrating doing that as well as not being able to hear my Logic audio during playback/record mode when I am trying to record via the USB3. WHat can I do? Thanks! If ther are both core audio, why can I not just use both of them at the same time? Why must a switch back and forth? Thanks!
[email protected]

THanks everyone! awsome article! Thanks for posting it, nh!
The weird thing is, once I go up to the Menu and select Open Aggregate Device Editor in the AUDIO/MIDI setup utility and try to add a new Aggregate Device setup (step # 6 from the link), the only audio device available is the "Built-in Audio". What's weird is when I have the main Audio MIDI Setup utility open, every single drop-down menu/tab has the "Direct Mix USB 3 1.0.9.1" device right beneath the "Built-in Audio" option. To me that says that the core audio device is indeed recognized by my computer (obviously since I can record with it using Logic). Can anyone help me with this one? Any suggestions?
Not that it should matter but, the hardware audio interface that I am using is made by the no-longer-existant company once known as Aardvark. I actually had to purchase a third party Core Audio driver just to have it recognized by OS X.
This is the website where I purchased my audio driver :
http://www.usb-audio.com/
A little more on how this device and it's core audio driver function within Logic . . . (Hopefully this might clarify something I may be screwing up) . . .
I launch Logic with its default Built-in Audio which allows playback of audio from the app. I than go up to Audio Hardware and Drivers and than drop the flip down Driver menu down to the second option, "Direct Mix USB 3 1.0.9.1." Logic than prompts me that I should try to (re)launch Logic Pro to load the appropriate CoreAudio.. I do that. Now I am ready to record guitar through the Direct Mix USB3, I just can't hear anything (unless I use head phones as an output from the Direct Mix).
Anyway, you all probably already knew what I meant so explaining that was pointless. But my question is, if the Driver is obviously recognized by my comp in both the Audio MIDI Setup and in Logic, than why won't the Direct Mix device show up as a possibility for setting up an aggregate device? Any suggestions? Thanks!

AE CS5 is not using Multiple Cores

I have a six core Intel I7 980X machine which i've got running at over 4GHz, yet AE is completely not making use of this speed.
I've turned on "Render Multiple Frames Simultaneously", and set it to use all cores (it detects 12 because of hyper threading on the I7 CPU's) and this does nothing for both the Preview window/working area or when actually rendering a video in the Render Queue. It uses about 9% at most of my CPU, that's not even 2 full cores.
I also have two SSD drives in RAID 0, they're Crucial C300 SSD's, pretty much the fastest you can get, infinitely faster than any Hard Drive, yet again... not making use of these it seems. I also have 12GB DDR3 running at 2GHz, i've set AE to use 9GB of it, as much as it will allow.... yet i cant even work with HD 1080p material and get near to smooth performance or even play it smoothly with or without effects applied, atleast with the video/viewer window near to 1080p size. Really pathetic. Premiere Pro on the other hard does a much better job but still dont fully make use of the speed and cores available. Adobe Media Encoder also does not use all cores.
Other software and even games make way better use of these cores than Adobe software seems to.
I've got two ATI 5870 graphics cards in Crossfire mode, they have the latest drivers. Performance is like this on any driver version though, but as far as i know none of this software makes use of the GPU's like it does with certain CUDA based Nvidia cards. I'd still like it to actually make use of my other hardware though.
I'm most bothered about AE, so any ideas why AE CS5 is [edited] so badly?
This is on Win7 x64.
Thanks for your help!

I've atleast made the renderer work a little faster by ticking "Enable OpenGL" in the Render Settings, and increasing the amount of used graphics card RAM to 800MB.
I also tried doing what those Blog posts said in the FAQ links - It has not helped much, if at all. So i tried a few different other RAM settings too, which didn't really help.
Then i put the video files on my SSD drives, and that helped a little. But not much difference still overall, very unimpressed with AE CS5 performance. It's took me hours to put together a 1min 30secs video that has 6 video files in total with some lens blur and colour grading effects applied, that's just silly, even for often slow Adobe software.
Cant see this happening but i'd like it if Adobe almost completely focus on performance for CS6 and hardly add any new features. While also making use of the speed of Solid State Drives and having GPU's also made use of more. I mean my SSD's are capable of reading around 600MB/sec and doing 40,000 I/O's per second but none of this is being made use of.

10.4.8 keeps both Cores 'Working'

Hi everyone,
I noticed that using 'QuietMBP' doesn't have an effect anymore, 10.4.8 must keep both cores working as the 'Ghz' status in CoreDuo Temp stays at 2.17ghz until the computer idles when i'm doing coursework or something, so just wanted to say thank you Apple!
Danny

Danny, although I've seen other posts saying that 10.4.8 keeps the CPU frequency at max, that's not the case on my 2.0 GHz MBP. And the total % use of both cores averages (as before) about 5%.
Hardware Monitor shows what I would expect at light load, with the frequency almost always at 1333 MHz, with peaks to 2 Ghz when more work is demanded of the processors. After a period at idle the frequency drops to 1000 MHz.
Contrary to the specs reported below, I'm running 10.4.8. (Profile doesn't give me the option to select 10.4.8.)
All in all, performance hasn't changed noticeably with the update. I'm still getting download speeds of 450-500 MBS from the Net via my WiFi network, which is OK for my 4 megabits/sec. cable broadband. No connection problems now, or previously.

Bind only using 1 core

Recently started using bind as one of our dns servers, and according to graphs on our cacti server, only 1 core gets used. It goes up to 10% cpu usage while the rest sit idle at 0% and sometimes a small spike.
Now on a ubuntu dns server which is a dual core, both cores go equally up in cpu usage, about 5% on both.
Also added the setting -n 4 to /etc/conf.d/named to see if that would make a difference but doesn't look like it.
Is there something different with bind on ubuntu that is missing on bind on archlinux?
Ubuntu: version: 9.5.0-P2
Archlinux: version: 9.6.0-P1 (version.bind/txt/ch disabled)

Actually figured out afterwards I can get the current one from: http://repos.archlinux.org/viewvc.cgi/b … D?view=log

How do I set upmy Imac to allow using both my computer speakers and a Bose SoundLink system as outputs at the same time. I can use one or the other, but not both.

how do I set up my Imac to allow using both my computer speakers and a Bose SoundLink system as outputs at the same time. I can use one or the other, but not both. From systems Preferences I must select one or the other. I want both to work all the time.

Hi,
I would recommend you to use 0FI_AP_4 rather using both, particularly for many reasons -
1. DS: 0FI_AP_4 replaces DataSource 0FI_AP_3 and still uses the same extraction structure. For more details refer to the OSS note 410797.
2. You can run the 0FI_AP_4 independent of any other FI datasources like 0FI_AR_4 and 0FI_GL_4 or even 0FI_GL_14. For more details refer to the OSS note: 551044.
3. Map the 0FI_AP_4 to DSO: 0FIAP_O03 (or create a Z one as per your requirement).
4. Load the same to a InfoCube (0FIAP_C03).
Hope this helps.
Thanks.

Can I use both newly cloned MBPR retina and old-MBP with same Time Machine

When my new-MBPR retina cloned from the old-MBP back up in Time Machine via migration assistance, will this newly-cloned MBPR continue thereon backing up with the same old-MBP back up in Time Machine? I.e. continuing same timeline?
And what happen to my old-MBP back up, if I continuing to use my old-MBP with the same Time Machine on? Will TM recognised 2 different MBP and thus creating 2 back ups? I seem to have problem to keep 2 MBP running with same TM. Programs not responding even force quitting them!
And what should I do to use both? Appreciate your help. Thank you.

OK, but in general I can use this one device as both file storage and Time Machine.
I thought that (for some reason) once I set up the Time Capsule to act just as Time Machine storage I would be unable to access it as a plain file storage.
I have just tested it now, and it seems it can work as both - file storage and Time Machine. I can see the Time Machine backup file on it and folders where I can dump regular files.
The only thing I would need to occasionally do is delete some old backups to keep Time Machine segment below 1 TB just so I have plenty of space for regular files.
This thing is awesome. :)
