Only one CPU core is working during video export from Premiere Media Encoder

Windows Resource Monitor showed cores 'parked' at first. I was able to turn that feature off using regedit. They no longer say they are parked'. but still only one core is at 100% while the other seven cores are at close to zero %. Windows 7 Ultimate SP1 64-bit. i7-2600k processor 3.4 GHz running at 3.8 GHz XMP setting. ASUS P8Z77-V motherboard 32 GB RAM.
I had this problem in the past and fixed when I turned off core parking. But, I recently clean installed Windows and problem has returned. I contacted Microsoft and they assured me that the problems lies with Premiere or AME.
it just took over an hour to export a video that should have taken 10 minutes

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!!!

Again, I bought a VERY expensive machine based on your white paper that recommended Dual Xeon Workstations. Please, Please Give us the product you PROMISED!!!

Only one CPU core recognized [solved]

For some reason the kernel only recognizes one CPU core out of two. I'm not completely sure at which kernel upgrade it disappeared but it is gone in 2.6.36 and 2.6.37. I know it was still there in september 2010 and earlier. I'm using a x86-64 kernel.

I have tried adding the kernel options "acpi=off noacpi apic=off noapic" as to the suggestion of a ubuntu bug report in launchpad but it didn't help. I also disabled ACPI in the bios but I'm still limited to one cpu core.
Any ideas?
[SOLVED]
I just doublechecked the BIOS settings and it had the CPU Core Control set to manual and one core was disabled. I set it to auto again and now both cores are recognized correctly. I don't recall ever touching this setting but at least it works now. Maybe a bios update actually changed the setting or (more probable) a friend of mine.

Choppy and lagging playback from videos/animations exported from Cs4 (Media Encoder)

Hello!
I got Creative Suite 4 (Production Premium). I usally uses AE and PrePro, saves the project and uses Media Encoder to export the footage. My filmcrew got a Sony HDR-200 (I think) who saves in AVCHD, m2ts full HD.
First I edit the clip with Sony Vegas... Cut the things I do not want.
Then, I applie visualFX with After Effects and sometimes Premiere Pro. Saves the project. Fire up Adobe Media Encoder and selects "add After Effects Composition".
I always render in:
H.264
HDTV 1080p 25fps
PAL 16:9 Ratio
The Video was/is original i:
Sony AVCHD (m2ts)
1080p 25fps
Everything seemes ok. No error messages or anything like that.
Next step, I import the footage (from any Cs4 application) into Vegas, Movie Maker or whatever software.
The whole clip, is "choppy". Frames mixes together. The footage is choppy even in Windows Media Player, Winamp... Not just Vegas...
Example: My actor is going to stand up from the couch. While rising, several frames from when he sat and when he has risen appears. The mixes, last ca. 2 frames each.
Summary: All Cs4 products exports choppy video... Media Encoder or not... Same problem.
Please help me!

Database uses only one cpu core from 16 available

Hi,
we have an server with 16 CPU cores, and we discovered from em that it uses only 1 core with 100% and the others are idle.
the initialization parameters for CPU are:
cpu_count 16
parallel_threads_per_cpu 2
resource_manager_cpu_allocation 16.
What can we do to use all 16 cores.
Regards
Nicoale Ancuta

Very interesting poit of view, but since I have for some period of time 1 core on 100% and other cores are idle or 0%,
I don't think that we can say that linux and oracle database 11g is using the best from that server, can you?Well, I did not offer a point of view. I offered fact - a reason why on x86 architecture it is faster to keep threads on the same CPU (if sufficient CPU capacity) then run such threads across CPUs.
As for what you are seeing - we cannot see it. So the only data we have is what you offered. And that does not suffice in making any kind of call as to why you are seeing, or even describing the symptoms correctly.
Why don't you try another example? 3 client server applications. Each client post a request (huge update 100% CPU, small update 0% CPU, huge select 100% CPU). What the server does, it switches between those 2 huge requests an uses only one core on 100% abd the others 15 are sleeping. Why don't use each request on different core and reduce the time?Define "+huge request+". Database operations are typically I/O intensive - not CPU intensive. There are also a number of processes. So if PMON for example is showing high CPU, then that means something different as when DBWR is showing high CPU, versus a dispatcher process showing high CPU.
So you need to provide a lot more detail for us to speculate as to what the problem could be, never mind offering a solution.

I am trying to export email from THunderbird to Mac Mail - all seems to go well but only 1 email is imported in Mac Mail. Any solutions would be greatly appreciated

You might have more luck creating a Gmail account, uploading all your mail there, and then using IMAP access.
Then you have easy access to your email from any device, and Gmail integrates really nicely with all your IOS devices as well.

Issues with depreciating FLV and F4V video formats from Adobe Media Encoder 2004

Hi Adobe
There are a couple of issues that have come to light with the removal of FLV support from AME 2004. Please can you provide answers to the following:
How do we set up/create Flash Que Points in video, now that the FLV format has been removed for AME 2004? - This is something I use a lot for adding dynamic text to video in Flash projects.
How do we export video with Alpha, without the FLV format, which can then be used in Flash? - This typically is used to overlay presenter to camera (on green screen) on flash animations or interactions etc.
More info on these issue on the following video forums:
Re: How do I use Flash Que Markers without the ability to export to FLV or F4V in Premiere Pro CC 2014?
Re: FLV export gone.. need alpha channel in video for Flash

I know this already - what worries me is going forward, there is no alternative to using these features. Adobe has basically made the new versions of their software unusable to me and other users looking to use 'Flash Que Points' or 'Alpha in video'. What Adobe should do is provide a modern alternative, before ditching these formats. - Doesn't really make any sense!
The other big question is, for how long will they provide access to the older versions????

Flux montage video et encodage premiere, media encoder, encore

Bonjour
Je me permets de vous poser quelques questions car j'ai un problème au niveau "optmisation" et travail en flux montage vidéo etc. J'essaye de vous détailler mes méthodes de travail et je cherche à éviter de perdre mon temps à cause des problemes d'encodage.
En effet, je commence par monter les séquences vidéos sous adobe premiere cc. Je précise que je travaille tout au format FULL HD. Ce sont des fichiers vidéos non compressés en HD avec un reflex 5D Mark III. Et je mets donc la résolution maximum.
Une fois la séquence vidéo entièrement montée, j'exporte le projet final sous un seul fichier vidéo unique sans compression, je garde toujours les mêmes formats. Par ex, mon fichier final pèse 15 GO pour une durée d'1H environ.
Ensuite ce fichier unique Full HD, je lui "convertis" au format bluray 264 grâce au logiciel Adobe Media Encoder.
Ca me donnera un fichier unique d'environ 5 GO avec une très bonne qualité d'image. Ce qui veut dire que je pourrais le "graver" sans probème sur un dvd double couche par ex.
Ensuite je finalise par le dvd authoring qui est adobe encore CS6 ( malheureusement, pas de version récente).
Le fait de prendre un fichier réduit, je me suis dit que je n'aurais plus besoin d'encoder et que je pourrais finaliser le projet rapidement.
Mais en fait, non, il y a toujours un transcodage à faire sous adobe ENCORE CS6.
Comment éviter cette fameuse étape d'encodage... Je souhaiterais garder la même taille et exporter plus rapidement. Pourtant, j'ai choisi d'exporter au "même format" mais ca encode toujours...
Ca me fait toujours des "pertes d'encodage" inutile sous adobe encore ...
Je ne sais pas si je me suis fait bien comprendre et j'espère trouver des aides ici ...
Sinon, je n'ai pas compris le fameux adobe bridge. Si je comprends bien, tous les fichiers/dossiers sont au même endroit en utilisant plusieurs logiciels différents..
Un peu comme le principe d'utiliser adobe encore CS6 et ouvrir directement sous photoshop pour "retoucher" ou modifier les menus et ca "modifie" en temps réel pour adobe encore CS6 ?
Je vous remercie de votre attention...

For some reason, I can't compile a video or image sequence anymore with Premiere, Media Encoder, or After Effects... All CC

I have been working on a video for awhile now and I've recently noticed that my .flv export format has been removed from my choice of encoders. I export from Poser Pro Game Dev to Png Image Sequence. I organise a cam angle in After Effects...I re render out to a png image sequence.. continuing to hold quality. Then when a scene is done; I use Premiere to export a 1080 by 720 wmv format 29.97. But now I can't encode from Premere, Media Encoder, or Affter Effects. Please ...Any help would be much appreciated.

Hi,

Check this for more information: removal of FLV and F4V export features from Adobe Media Encoder, After Effects, and Premiere Pro | After Effects regio…
But now I can't encode from Premiere, Media Encoder, or After Effects.
What exactly happens when you try to export?

Multisim 11 only uses one CPU core during simulation

Hi,
Just recently I've been using MultiSim again, v11 if that matters, and simulating goes slow, to my opinion that is.
Now there are two things that I've noticed:
- Multisim only uses one of two CPU cores during simulation, not both;
- I've enabled CPU throttle (AMD's Cool'n'Quiet) but corespeed remains very low even though Multisim needs CPU power while simulating.
The simulating of a NE555-based LED-flash circuit requires about 28 seconds to get to 100ms in the simulation. Now if I can get the CPU to throttle up, by for example having Prime95 stress one of the two cores, then the simulation only requires 12 seconds to get to 100ms.
So here are my two questions:
1. Is Multisim 11 capable of using more than one CPU core while simulating? If yes, how can I get it to use more than one?
2. Probably not the right forum to ask, but is there a way to force Windows 7 Ultimate x64 to throttle up the CPU when Multisim starts simulating? Since Multisim does not seem to stress the only core it uses enough to throttle it up. Using Prime95 on one core does trigger a throttle up.
With regards,
Bart Grefte
Relevant specs:
Windows 7 Ultimate x64
Multisim v11
AMD A4-3400
16GB RAM

Completely forgot this topic....
Is there a good reason why there is no multicore support? Multisim can certainly use it for simulating.
As for the CPU throttling, I found a batch that can increase/decrease the "minimum processor state"-setting and it works immediately, no reboot required.
@echo off
powercfg.exe -getactivescheme > "%userprofile%\appdata\~apo.tmp"
set /p v_currentscheme= <"%userprofile%\appdata\~apo.tmp"
set v_currentscheme=%v_currentscheme:~24,36%
del "%userprofile%\appdata\~apo.tmp"
powercfg -setacvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -setdcvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -s %v_currentscheme%
exit
Usage is simple:
Start -> run -> c:\pathtobatch.bat 100
for "minimum processor state"-setting at 100%
Start -> run -> c:\pathtobatch.bat 5
for "minimum processor state"-setting at 5%
Please note that "set v_currentscheme=%v_currentscheme:~24,36%" is not the same for every language. The original batch had "set v_currentscheme=%v_currentscheme:~19,36%" (most likely for the English version of Windows 7), but since my Windows install is in Dutch, I had to change it in order for it to work.
Running the batch with @echo off removed will show why.

Dual Core G5 using only one CPU

Anyone has an idea about what happened to me last week? Here is what happened:
I let my dual 2.3 GHz Power Mac G5 run over night to run a certain task. When I came back the following morning, the fans were running like crazy and the computer was frozen. I had to reset it. After that it started up, but from then on only used one CPU. In System Profiler as well as in Activity Monitor, only one CPU is shown. After some more days, it would not turn on anymore, not even with one CPU.
What to do now? Thanks for helping me out...

It is insurance. It keeps a system running so you can do a safe shutdown. It protects the boot drive from directory corruption. Protects wired ethernet port from getting fried (someone last week's sad tale).
"Nice idea." Well, yes. Can you drive a car without insurance? I'll take UPS and help protect my systems.
If you want to leave a system running unattended and not come back to a dead or dying system... I have read enough tales of woe that "but it was working yesterday" and "we've had some storms but lights stayed on" that I don't take chances. And I often give advice that isn't 1:1 correlation. Like "backup daily" and "run disk repairs before there is a problem."
maybe it over-heated, too.

Logic 8 using only one CPU while bouncing

Whenever I bounce a project, Logic 8 uses only one CPU. It also spikes this CPU completely, with the CPU meter going into the red area, which is why I am rather keen on persuading Logic to distribute the load.
Any ideas?
(I've given the support document with tips on how to balance multi-core performance a good read, but it doesn't seem to say anything on this particular subject, and following the advice in the document does nothing to change my CPU load.)

Bouncing is a single core process. Just like rendering is in Final Cut Pro. This won't change until Leopard and Apple's ProApps get better at handling multiple cores.
It's redlining because the processor core is working as fast as it can. Computer processors don't just randomly run slower, they use their resources for the tasks at hand. If it only used 50% of a core, the bounce would take twice as long to process.

Parallelism in oracle using only one dual-core processor

Hi, is usefull or could i use parallel execution in oracle using only one dual core processor?
Can someone explain me why?

Hi
To take advantage of parallel processing you need enough resources (mainly CPU and I/O). If you run serially and the bottleneck is the CPU, then parallel processing might help. On the contrary, if the bottleneck is located in the I/O sub-system, throwing more CPU to it would not make things better. So, it's a question of balance between the CPU and I/O resources you have.

Color using only one CPU?

When rendering with Color it seams that it using only one CPU, according to "top".
Is it possible to make use of all CPUs?

Color's work is done on the GPU not the CPU, so unfortunately, the answer to your question is, no.

MobileDeviceHelper running @ 100% on one CPU Core

Hi, anyone suggest anything to fix one of my CPU cores runs MobileDeviceHelper (32Bit) at 100% consistently after iTunes is started.
The machine is a new build with Windows 8 64bit all updates and patches applied. All latest manufacturer chipset and other relevant drivers and every other part of the machine works perfectly. If I end the process, distnoted (32 bit) then replaces it and takes over with another core running at 100%. Ending that process and mobiledevicehelper comes back at one core 100% usage, then ending that and it behaves.
I have tried restarting the machine, installing updates, disabling the task in task manager, resetting the network adapter (winsock reset) and disabling ApplePush, and itunes helper at startup but am out of ideas now! I haven't even sync'd my phone to it yet.
Im fast thinking iTunes seems to be getting more buggy each release (I haven't been able to burn an audio cd on the new machine as it crashes while attempting to, but other software can burn the same playlist and file after dragging out of the iTunes playlist) yet iTunes on my Macbook runs fine!

oh and its iTunes 12.1.1.4 64Bit with Windows 8.1 Pro 64Bit all latest updates.
As a workaround I have found the two files, renamed them so iTunes cant call them and everything still works fine which begs the questions what are they doing that uses 100% of one CPU core! I haven't setup my iPhone as a remote, or my AppleTVs yet, hoping they don't rely on these services!
