Single Core MBP

Let's see, I have resorted to installing the developer tools and going "core solo" to get rid of my CPU hiss. Naturally, now I'm wondering how drastic the performance defecits are. Anyone have any idea?

I guess you could get hold of one of the various benchmark programs that people run to test performance and then run these with both single and dual core and see the difference.
In the real world, it's entirely your perception that matters. If you feel that performance on a single core is adequate for your needs and makes you feel comfortable due to lack of hiss then that's all that matters. If you are doing a processor intensive task (e.g. encoding video, working in iMovie, etc.) then you could just consciously enable the second core at that time to get more power, the hiss won't be there at such times due to high processor activity. Once the task is finished, you can disable one core again.
I personally think it is regretable that users pay good money for a "pro" dual core machine and then have to resort to crippling the full potential of that machine in order to work effectively and peacefully on it. Alas, we all have to do what it takes to achieve peace of mind. Enjoy your silent single core computing experience!

Single Core vs. Dual Core - Temperature Differences

Does anyone else notice that CPU temperature is affected by turning off one of the cores using the apple CHUD tools? For me, the extensions report that it's running 15-20C hotter when I'm running single core. The case temperature seems to confirm this fact as well. Can someone with CHUD installed please try to duplicate this?
I've got a stock 15.4" MBP 1.83GHz/512MB - W8613.
Macbook Pro Mac OS X (10.4.6)

it also uses the battery more. I conjecture that disabling a processor also disables power management. This solves the hiss because the hiss is due to power management, but at the cost of more heat and battery usage.
I suggest using quietmbp rather than disabling a core.

Unable to capture data from Serial port using LVRT2010 in single core pentium 4 machine

I am using application written in Labview using windows Labview
Runtime environment 2010. Application creates a tunnel to intercept data from
Serial port.
My problem is, Currently, I am using single core Pentium
processor. When I am trying to intercept the data between COM1 and COM7 (COM 7
is a virtual port) it is not able to capture data.
When I am running Labview RT environment using dual core
processor machine it is running normally. I wonder whether it could be the compatibility issues with
single core Pentium processor.

Hi Magnetica
Are both of the machines running the same runtime engine,
drivers ect?
Have you had RT applications running on this
machine before?
Is the development computer a 64bit machine?
The processor is a supported model (See link below).

Extract report only runs on a single core

I am running the following extract report on a dual quad-core processor server with 32 GB ram and when I suppress empty rows the process runs on a single core which of course runs at 100% slowing down the process, but if I do not sppress rows all cores are used. Has anyone else experienced this or can i modify my report to improve performace?

One item unrelated to the DimBot issue:
If you have a time period that can be used to restrict on (for suppression), you can use the restrict approach rather than the sup missing, ala:
<RESTRICT (@DataCol(11) <> #Missing )
I'm not sure I would attempt this if you had to deal with multiple restrict's though -- I'm also not entirely convinced the savings would be substantial, but it could be based on the multiple core aspects.

Adobe Media Encoder only using single core of CPU (core parking has already been disabled and did not solve the problem)

I only edit videos every few months and the last time I edited a video was around 6-9 months ago. At that time, I noticed AME was only using a single core of the CPU and contacted Adobe who instructed me to disable core parking, which worked. After disabling core parking AME used 100% of all 12 logical cores to process the video and all was good. Then last week, I decided to edit another video and noticed AME was very slow and checked and it was again only using a single core to process the video, but core parking is still turned off. By slow I mean that a 10 minute video with the lens distortion correction preset and one video transition effect is estimated to take nearly 3 hours to complete. For comparison, the GoPro software processed the same clip with the same effects in 20 minutes. Also, through troubleshooting with Adobe over the last few days, I have also tried downloading previous versions of the software but the prior versions have the same issue.
The video I'm trying to edit was shot on a GoPro Hero 4 Black with 1080p Wide at 60 frames per second. The default video format for GoPro is .mp4. The output settings I'm using when I export from Premiere Pro to AME are H.264 with the YouTube 1080p HD.
My system:
ASUSSabertooth X79
Intel core i7 4930k (6 physical cores, 12 logical cores)
16GB DDR3 Quad channel RAM
Samsung 830 SSD 128GB
NVIDIA GeForce GTX 460 (not CUDA compatible, I know)
Please ask if you need any additional information to help solve this problem.

This has been driving me CRAZY... so going over the message boards from 2 to 5 am this morning I found the best explanation I have seen. The problem is that Adobe Creative Cloud is NOT "Processor Group Aware". Windows parses any more than 36 cores into "Processor Groups" and while the Pro version of Windows 7 & 8 can handle 256 threads they have to spread them across multiple processor groups.
Simple Version: AREA | How many cores does 3ds Max support?
Microsoft's Explanation: Processor Groups (Windows)
Clearly, this is an Adobe Problem... If any engineers are reading this PLEASE review the below and incorporate it into your next build of Creative Cloud!!!

CS4 and single core processors

Hi,
I have a Mac Mini with a 1.5 GHz Intel single core processor and i want to buy Creative Suite 4 Web Standard to use on it.
But when i read the requirements for CS4 it mentions that a Mac should have the following:
PowerPC G4 or G5 or multicore Intel processor
Does CS4 work OK on a Intel single core processor?
Is a multicore processor specified because a small number of features benefit from it?
Any advice would be appreciated.

I used InDesign CS4 for a while on a 1 Gig 800MHz G4 tiBook. It was reasonably satisfactory given that I knew I was working in an underpowered setup -- I've since replaced the tiBook with a MacBook Pro with 4 Gigs.
I think that if you stick to your "one app at a time" philosophy, you'll be happy enough with the Mac Mini. I think Adobe was just reducing the testing and support load it had to deal with by apparently excluding older processors.

Processor question - Dual core vs. single core.

I currently have an Aspire 6930 laptop that I bought about a year ago on clearance from Best Buy. I'm quite happy with it. It has an Intel Core 2 Duo processor (2.0 GHZ, 800MHz, FSB, 2 MB L2 cache), 3 GB DDR2, 320 GB HDD if that means anything. I'm not a computer geek so really don't know much about this stuff.
Our old laptop is a modular laptop (about 4 years old) which my husband is using (I won't let him mess with my Aspire - long story) and it's pretty much falling apart. None of the USB ports work, the CD/DVD RW is broken, one of the hinges is busted so it won't close properly and it runs slower than a snails pace as he's dowloaded any and all "speed up your PC" and "diagnose your PC" programs from the web - if it's on the web it must be true, right???? Anyway, I've taken pity on him and have decided to try to buy him a new laptop as a combination 10 year anniversary/42nd birthday/Christmas present. Money is a HUGE issue as I'm a SAHM and have been pinching pennies and clipping coupons from the grocery money to try to come up with some funds for this surprise. I'd like to stay around $400.
I've found this one at Best Buy and it has good reviews.... http://www.bestbuy.com/site/Acer+-+Aspire+Laptop+with+AMD+Athlon%26%23153%3B+Single-Core+Processor/9...
But it says it has a single core processor. What exactly is the difference with single core vs. duo core???
We are not gamers. DH basically uses the computer to surf the web, watch Youtube video's, upload and download photo's, burn DVD's, etc. He does talk with family overseas so I would need/like to add a webcam.
I was also looking at this Asus model... http://www.bestbuy.com/site/Asus+-+Laptop+with+Intel%26%23174%3B+Pentium%26%23174%3B+Processor+-+Mid...
But the Asus has a Pentium processor which I've heard isn't the best???? Also, it's over $150 more. Is the duo processor and increase processor speed (1.6GHz vs 2.1 GHz) really going to increase the speed/response time significantly for what we do on the computer?? An extra $150 is going to be really tough for me to come up with but if it will truly make a significant difference I will try to find it somewhere.
Your thoughts/recommendations would be appreciated.

Thanks for the input. We really don't have the space for a desktop which is why the laptop worked so well for us. The only place to put a desktop is on the kitchen table and then we are always taking it apart when family come for dinner (which is often). I thought of netbook, but it does seem so limited. My husband is an amateur photographer and I would like the larger screen so that if he decides to persue this he would be able to do some basic photo editing, etc.
I think I will go with the dual core processer. BB has an HP that is $429
http://www.bestbuy.com/site/HP+-+Laptop+with+Intel%26%23174%3B+Pentium%26%23174%3B+Processor+-+Black...
and then another HP that is $499
http://www.bestbuy.com/site/HP+-+Laptop+with+Intel%26%23174%3B+Pentium%26%23174%3B+Processor+-+Piano...
and I can't seem to find the difference?????? Except the cheaper on has more RAM??? Doesn't seem to make sense.
Thoughts on the HP???

2.7ghz Dual Core verses Single Core

Hi, I have a Pro Tools system with PCI audio cards that I sunk quite a bit of money into. Needless to say, I'm stuck in PowerMac purgatory until I come up with the cash to make a total PCIe conversion. With that being said, I am now trying to determine what the absolute fastest (dare I say the best) PowerMac was before Apple moved on to greener pastures. What I've been able to find with some light research is that they built the obvious 2.7ghz Dual Core machine but also momentarily built a 2.7ghz Single Core machine for some reason. Can anyone shed some light on the advantages/disadvantages between the two? Thanks!

You have received misinformation. The dual processor (not dual-core) model was the only one offered. Only the 1.6 GHz and 1.8 GHz machines were ever offered with a single-processor.
All G5s at 2.5 GHz and above were also liquid cooled, so you may want to take that into account. Should one of them develop a leak, the repair bill is astronomical, assuming you can't coax Apple into fixing it as a design defect.

Single core

Hello,
I would like to ask if anyone could refer me to some reading material that explains the difference in recommended LabVIEW programming for single core and multi core machines?
Assuming I had a multi VI program that runs fine on a quad core, but barely runs on a single core. Obviously the quad core is more likely to provide better performance, but I am vaguely aware of the different programming methods which are more suitable for the respective type of cpu.
I do not ask for any specific help with any vi or issue, I would just like to read up on this subject. I looked around a little but did not find very much. Any links or suggestions would be greatly appreciated.
Thanks

Please tell more about what you think you should be finding but are are not finding.
I know of things to watch for when going from single core to multi-core but little "rings a bell" going the other way... EXCEPT adding a "zero-millisecond wait" to all loops. The presnece of a wait tell she secudler this loop can be interupted. Without the timer, LV will "read the code" as "please run as fast as possible, and if that means don't give up the CPU, so be it.".
See alos this search on "Cooperative multitasking".
Ben
A wait is not always required. It won't hurt, but there are other pieces of code that will allow the scheduler to evaluate if other tasks are ready to run. If you have any queue or notifier VIs they will allow the scheduler to run as well. There are probably a few others. I am reasonably sure that any VI with a timeout input will allow the scheduler to run.

Rendering MP4 with AME from After Effects is always single-core?

When I render MP4 from After Effects CC 2014.2 (by AME) then rendering always is slow and only single-core, despite that in AE prefs Multiprocessor rendering is set.
Why?

I have made quick test now.
AE's Render Queue: render time 53s - average CPU load about 50% (12 cores, 8 rendering threads at this case) - 8 threads active in Process Explorer
AME Render: 2m08s - average CPU load about 20% (same machine) - 1 thread active in Process Explorer
(please note that this was simple project; at 8active/12total cores this should be 66% or even more total CPUs load, so probably much time was disk I/Os - if only was 50% of total CUP load)
So essential question is:
Is AME CC 2014.2 renders AE projects as set in AE prefs in multiprocessing?
Or maybe there is separate option in AME to turn on multiprocessing on AE's projects?

Changing from Dual Core to Single core

If you ever need to change from dual to single core you just have to call Apple Technical Support to learn how to do it. Some third party software vendors software dos not support multi-threading. So it sometimes causes a kernel panic which unexpectedly quits the program.

ComputerGenius,
the easiest way: download and install the developer tools. These contain a preference pain called "Processors". With that one you can deactivate processors/cores individually.

Dual-Core or Single Core?

I wanted a new phone for my birthday. At first I wanted the Sony Xperia Play, but it didnt come out in time. I also see the reviews for the phone, and they dont look so good. So, I am now thinking about either the HTC Thunderbolt, or the HTC Incredible 2. But I realized that they both are single cores, not dual cores. Should I be caring for the amount of cores? I have an iPod Touch 3G, and I like the speed of that device. I'm not sure if it has dual core or single core, but i am fine with that speed. I also want an HTC because of HTC Sense. I like its UI better than Motorolas or Samsungs. And I dont feel like rooting the phone either (yet). So, should I be caring about the Dual Core or is a Single core fine?

If you're a tech nerd: wait for a dualcore, or you'll have CPU envy. If you're not a tech nerd, it honestly doesn't matter, get whichever phone has the features that matter to you (in this case, HTC Sense).
The Xperia Play makes me sad though... both because it's not out yet and because it's (so far) VzW-exclusive in the US V_V

Single Core CPU - REQUIREMENTS

Hi ALL Hope I'm in the right place this is a hard hardware isssue I can't seem to figure. Here's the deal: Old Toshiba Satellite (circa 2006) with Intel® Pentium® M Processor 780 (2M Cache, 2.26 GHz, 533 MHz FSB) with MMX instructions, SSE / Streaming SIMD Extensions, SSE2 / Streaming SIMD and 2 NX / XD / Execute disable bit. For the new guys out there - yeah this is old - it's single core. Remember those? OS win xp pro (32bit) 100% fully patched and with no failed updates. Just waiting to install the MS Skype update. So will this setup run Skype with a webcam and if it will which webcam should I buy?

You can run a webcam with that setup. I would suggest you buy a webcam that is designed to run on a single core. I would suggest getting at most a 720p camera or under [2Mbit video (not photo capture) or below] that is compatible with Windows XP. The higher resolution a camera is capale of, the more likely it will attempt to negotiate ata a higher resolution which will result in more CPU consumption. If you use a 720p camera and it determines to engage the higher resolution, don't be surprised if your CPU resources hit as high as 80% while on a call. Then again, it might not try and you could be fine even with a high-end camera. I would personally recommend getting a big brand name camera like a Microsoft Lifecam or Logitech series (I use both). Getting a generic brand might work great on your computer as well but it may work too great providing too low a quality that is acceptable to you or others with no room for improvement in the hardware.

Flash playback on Atom single-core found in Netbooks

Has anybody ever been able to play flash on a Intel Atom single-core CPU found in many Netbooks with an acceptable performance?
Even medium resolution Flash from youtube is extremely choppy. Is it just me or am I just doing something wrong with this gear?
Thank
McL

Hi, Many users with PC's and Mac have experienced video issues with the hardware acceleration feature in Flash Player. You might want to turn it off, since it's turned on by default. This is the Adobe test site. If there is an ad covering the Flash logo, just use the ad to Right click on.
http://www.adobe.com/software/flash/about/ and RIGHT click on the Flash Logo, click on Settings>
Display Settings and UNcheck the hardware acceleration feature.
I don't think the choppiness is related to your system specs. Since Flash Player is a browser plugin (ActiveX Control for IE) then any Toolbar, Anti-Virus and other addons can conflict with it and the browser itself. So you may want to pursue those if turning off the h.a. doesn't help.
This is a link to reviews on the Top 10 Netbooks that may have some info.

The various Manufacturers may also have forums and or reviews.
Perhaps others that use Netbooks will see your thread and comment further.

What the heck is Single Core, Dual Core, and Quad Core Processor Configurat

I am listing an eMac computer on ebay. I have all the information necessary except processor configuration. Do eMacs come with Single, Dual, or Quad processor configurations? Or does it vary? I don't even know what those are really.

Make sure to follow these steps when selling*:
http://www.macmaps.com/selling.html
As was already indicated all eMacs were single core.
Apple didn't start releasing multicore machines until the later G5s.
