Uneven processor core didtribution

Why does Logic distribute plug in processing unevenly?
I am currently getting regular Core Audio system overloads and my System Performance meter is showing core 1 and 4 running at about 30%, core 2 is unused and core 3 is running in the red (90%-100%). I am using all 3rd party plug ins with the exception of 2 instances of EXS24.
I have tried re-instantiating plug ins and setting up my local machine as a node. It makes no difference. It seems that all 3rd party plug ins want to use a single processor.
Does anyone know a workaround?

Welcome to the forum bof,
Mac-Pro Quad runs in Symmetric with Memory of Rams,
so it may be a case of the Rams being un-even.
Rams has to run in pairs for you to get the full 256/bits,
in the Memory performance.
Try taking out 1 Giz and allow Four Gizs of Rams,
and see what happens.
Secondly i am guessing use use Migration to cross over,
to the Mac-Pro,
if that is the case, the Machine will run like Molasses,
therefore its best to do a clean in-stall.
Before doing a in-stall back-up your stuff,
then erase all H.D. and re-format,
then install.
You only need to install OSX on the boot Drive.
No need for Apps on one H.D. and Sample on another H.D.
Put Apps/Samples on same boot Disk, Bay 1
and File/Audio on the other H.D. in Bay 2
the other H.D. other than the boot H.D. can be set to raid,
give-ing twice the speed if its two H.D. set to a Raid 0,
And the Forth H.D. for back-up which can be set also to Mirror
for the set of Raid.
Also get some form of Data-Recovery sofware in recovery H.D.
never know when the Sh£t hits the Fan.
Disk Warrior can be consider.
Hope all this makes sense,

Processor Core Cache Hierarchy Error in event viewer and BSOD

Hello everyone. Lately I have had some problems with random freezing, and I can't figure out what's causing it, hoping to get some help here.
I have a MSI X79A GD65 (8D) motherboard and 4930K cpu, currently running @ 4.4ghz, 1,33V, disabled all the power saver features.
The PC have been stable for almost a year without issue, and just recently the PC have started randomly freezing. It can be up and running for a whole week without problems and then suddenty freeze, or sometimes just few hours and then freeze. It seems like it always freezes when surfing the web, and it tend to happen during scrolling a website. It is never happening during gaming with heavy load.
The error message is following:
WHEA Logger A fatal hardware error has occurred.
Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 8
Things I have tried: Reverted back to stock speeds in bios, updated to latest bios, tried a other power supply and formated windows with newest drivers, no difference. Memtest does not show any errors, and the pc passes prime/intel burn test. Cpu temps are fine.
What more can I do ? Is there a chance that the CPU have taken damage from my "little" overclock ?

Hi,
Can you tell what were temps of the CPU while overclocked and under full load (Intel Burn Test)?
Also, did you try different RAM? And are you currently running RAM at frequency of....? (Reduce to 1600MHz).

How can I tell the VMware GdbServer stub to set a processor core during kernel debugging session?

I'm using the VMware DbgServer stub for kernel mode debugging a Windows X86 VM and I want to set a different thread (or processor) in order to get/set the processor context, but the DbgServer replies that the target only has one thread running.

Nick-
In my experience, the only tell is in the result with Lightroom unless your processor is dog slow. You can select PS as the active app. on my Mac and see it working.
You could also modify the action to not save and close, and then check History in PS.

Are AS3 timers make use of multi processor cores?

Can anyone tell if a Timer in AS3 will force Flash player to create a new Thread internally and so make use of another processor core on a multicore processor?
To Bernd: I am asking because onFrame I can just blit the prepared in a timer handler function frame. I mean to create a timer running each 1ms and call the emulator code there and only show generated pixels in the ON_ENTER_FRAME handler function. In that way, theoretically, the emulator will use in best case a whole CPU-core. This will most probably not reach the desired performance anyway, but is still an improvement. Still, as I mentioned in my earlier posts, Adobe should think of speeding up the AVM. It is still generally 4-5 slower than Java when using Alchemy. Man, there must be a way to speed up the AVM, or?
For those interested what I am implementing, look at:

If moderators think that this link is in some way an advertisement and harms the rules of this forum, please feel free to remove it. I will not be offended at all.

Hello Boris,
thanks for taking the time and explaining why your project needs 60 fps. If I understand you correctly those 60 fps are necessary to maintain full audio samples rate. You said your emulator collects sound samples at the frame rate and the reduced sampling rate of 24/60 results in "choppy sound". Are there any other reasons why 60 fps are necessary? The video seems smooth.
That "choppy sound" was exactly what I was hearing when you sent me the source code of your project. But did you notice that I "solved" (read: "hacked around") the choppy sound problem even at those bad sampling rates? First off, I am not arguing with you about whether you need 60fps, or not. You convinced me that you do need 60fps. I still want to help you solve your problem (it might take a while until you get a FlashPlayer that delivers the performance you need).
But maybe it is a good time to step back for a moment and share some of the results of your and my performance improvements to your project first. (Please correct me if my numbers are incorrect, or if you disagree with my statements):
1) Embedding the resources instead of using the URLLoader.
Your version uses URLLoader in order to load game resources. Embedding the resources instead does not increase the performance. But I find it more elegant and easier to use. Here is how I did it:
[Embed(source="RESOURCES.BIN", mimeType="application/octet-stream")]
private var EmbeddedBIN:Class;
const rom : ByteArray = new EmbeddedBIN;
2) Sharing ByteArrays between C code and AS code.
I noticed that your code copied a lot of bytes between video and audio memory buffers on the C side into a ByteArray that you needed in order to call AS functions. I suggested using a technique for sharing ByteArrays between C code and AS code, which I will explain in a separate post.
The results of this performance optimization were mildly disappointing: the frame rate only notched up by 1-2 fps.
3) Optimized switch/case for op table calls
Your C code used a big function table that allows you to map op codes to functions. I wrote a script that converted that function table to a huge switch/case statement that is equivalent to your function table. This performance optimization was a winner. You got an improvement of 30% in performance. I believe the frame rate suddenly jumped to 25fps, which means that you roughly gained 6fps. I talked with Scott (Petersen, the inventor of Alchemy) and he said that function calls in general and function tables are expensive. This may be a weakness within the Alchemy glue code, or in ActionScript. You can work around that weakness by replacing function calls and function tables with switch/case statements.
4) Using inline assembler.
I replaced the MemUser class with an inline assembler version as I proposed in this post:
http://forums.adobe.com/thread/660099?tstart=0
The results were disappointing, there was no noticeable performance gain.
Now, let me return to my choppy sound hack I mentioned earlier. This is were we enter my "not so perfect world"...
In order to play custom sound you usually create a sound object and add an EventListener for SampleDataEvent.SAMPLE_DATA:
_sound = new Sound();
_sound.addEventListener( SampleDataEvent.SAMPLE_DATA, sampleDataHandler );
The Flash Player then calls your sampleDataHandler function for retrieving audio samples. The frequency of those requests does not necessarily match with the frequency onFrameEnter is being called. Unfortunately your architecture only gets "tickled" by onFrameEnter, which is currently only being called 25fps. This becomes your bottleneck, because no matter how often the Flash Player asks for more samples, the amount will always be limited by the frame rate. In this architecture you always end up with the FlashPlayer asking for more samples than you have if the frame rate is too low.
This is bad news. But can't we chat a little bit and assume that the "sample holes" can be filled by using sample neighbors on the time line? In other words, can't we just stretch the samples? Well, this is what I came up with:
private function sampleDataHandler(event:SampleDataEvent):void
     if( audioBuffer.length > 0 )
          var L : Number;
          var R : Number;
          //The sound channel is requesting more samples. If it ever runs out then a sound complete message will occur.
          const audioBufferSize : uint = _swc.sega_audioBufferSize();
          /*     minSamples, see http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/events/SampleDataEvent.html
               Provide between 2048 and 8192 samples to the data property of the SampleDataEvent object.
               For best performance, provide as many samples as possible. The fewer samples you provide,
               the more likely it is that clicks and pops will occur during playback. This behavior can
               differ on various platforms and can occur in various situations - for example, when
               resizing the browser. You might write code that works on one platform when you provide
               only 2048 samples, but that same code might not work as well when run on a different platform.
               If you require the lowest latency possible, consider making the amount of data user-selectable.
          const minSamples : uint = 2048;
          /*     For the maximum sample rate of 44100 we still only get 1470 samples:
               snd.buffer_size = (rate / vdp_rate) = 44100 / 60 = 735.
               samples = snd.buffer_size * channels = 735 * 2 = 1470.
               So we need to stretch the samples until we have at least 2048 samples.
               stretch = Math.ceil(2048 / (735*2)) = 3.
               snd.buffer_size * channels * stretch = 735 * 2 * 3 = 2790.
               Bingo: 2790 > 2048 !
          const stretch : uint = Math.ceil(minSamples / audioBufferSize);
          audioBuffer.position = 0;
          if( stretch == 1 )
               event.data.writeBytes( audioBuffer );
          else
               for( var i : uint = 0; i < audioBufferSize; ++i )
                    L = audioBuffer.readFloat();
                    R = audioBuffer.readFloat();
                    for( var k : uint = 0; k < stretch; ++k )
                         event.data.writeFloat(L);
                         event.data.writeFloat(R);
          audioBuffer.position = 0;
After using that method the sound was not choppy anymore! Even though I did hear a few crackling bits here and there the sound quality improved significantly.
Please consider this implementation as a workaround until Adobe delivers a FlashPlayer that is 3 times faster :-)
Best wishes,

Pages '09 only uses one processor core?

Hello,
some days ago i had to open a document containing nearly 2.000 pages. Don't ask why.
Working with this document was quite complicated because Pages was responding very slowly. I used the activity monitor to see what was going on and i recognized that Pages only uses one core of my eight core MacPro.
I tested iWork on my iMac and MacBook Pro (both DualCores) as well: same problem.
Does iWork only use one processor core?
Kind regards,
roman

How much memory do you have in your system? I'll bet if you check activity monitor (applications/utilities) and go to system memory tab therein you will see lots of page outs. This happens with huge docs and little memory as the doc is being swapped between active operating memory and the hard disk The only way to solve this problem is to get more memory (not storage) in your system. For a 2,000 page doc you're going to need lots and lots and lots of extra gigs of memory. By the way - how big is the too big file of yours?
Number of processor cores isn't going to solve the issue if you have pageouts. It is a system memory/size of document issue and completely unrelated to how many processor cores you are using.

SQL Server Processor/Core Licensing and Windows CALs

I've scoured the internet for an answer to this question, so I'm assuming the scenario isn't as common as I think, or people are purposely looking the other way because they don't want to know the answer :)
The application in question is pretty simple - An ASP.net web application using ASP.net forms auth (no end-user Windows Authentication). Using Windows Server 2008 Web Edition, we've confirmed that no Windows CAL is required on the front-end web tier.
So then on the back-end data tier (SQL Server) it also seems pretty straight forward. As far as I can tell, the SQL Server licensing makes it pretty clear "...users who input data into, query, or view data through a web-based application... require
a CAL". So that makes it pretty obvious, you need a CAL or a per-processor/pre-core license of SQL Server.
Here's where it gets tricky... What about the licensing requirements for the Windows Server that SQL Server is running on? Do we need a
WindowsCAL for each connection from the Web Tier to the SQL Server? Note that Windows CALs and SQL Server CALs are completely separate in terms if purchasing, and nothing says a SQL Server CAL is of a higher
order than a Windows CAL (thereby covering both).
It would seem ridiculous (IMHO) to allow unlimited connections to SQL, but then dump you back to the CAL model on Windows (since there is no "unlimited" option in Windows Server). But licensing is a strange beast, and non-compliance is not
something I'm interested in.
Any insight with pointers to Microsoft documentation would be greatly appreciated!
Thanks guys,

For those of you who would like an answer on this without calling licensing support, here's the answer :)
Windows Server 2012 does NOT have a CAL limitation for "public" web traffic. I specifically asked about ASP.net Forms Authenticated users, and the licensing specialist said any website that uses anonymous authentication which then passes
auth onto some other back-end process (e.g. ASP.net forms auth) you do not need a Windows CAL. You DO need a Windows CAL if your application is somehow tied to services on the Windows box where the website user actually enters credentials which are authenticated
against the local account store or domain controller. So to me, that's a pretty simple answer -
anonymous auth = No CALs
integrated auth = CAL required
Ok, onto SQL Server... As quoted from my original post, SQL licensing makes it very clear that ANY connection to the database requires a CAL, even if it's multiplexed through IIS or some other middle-tier. Bottom line? Simple answer here as well:
public website with a SQL back-end = per-socket or core-licensing (since you can't count "CALs" on a public site)
Finally, the most illusive question (for me anyway). What about the copy of Windows running your SQL Server? the answer here was - No CALs required if it's purely a SQL Server connection. Meaning, if all your Windows server is doing
is running SQL Server and fielding query requests from your front-end IIS ASP.net app, you're do NOT need any Windows Server CALs. You obviously do need SQL CALs or socket/core licenses, which I covered above. You will however need Windows CALs
on your SQL Server box for any Support specialists or Deployment folks who remote into the machine using TS or using UNC file shares and such to work with the server.
Hopefully that helps someone else looking for a quick answer. And as the moderator noted, if that doesn't make sense you should definitely call the licensing specialist. They are very helpful and surprising quick to answer questions (without
any sales pressure).
Thanks for posting this, I am in the same boat. I will have a public facing web server and a backend SQL server. The web site requires all users to login so they can see the content. We use forms authentication as well (no Windows or Active Directory authentication).
The application does all the authentication itself using the backend database (credentials are stored in a database table).
I just called the licensing pre-sales number and spoke to a rep who said the web server would require CALs (or an External Connector in this case), because I am requiring people to login to view the content. He said it did not matter what the authentication
method was. I clearly explained the web application handles all the authentication, but he still said we would need CALs in this case because users must authenticate to access the content. He likened it to a museum. If you need to buy a ticket to get in to
see the content (in this case login to the web site), you need CALs he said.
He also said I would need Windows Server CALs/EC for the Windows server that hosts the database. I will be using SQL Core licensing, so no additional SQL CALs will be needed.
Just thought I would share what I learned.
Sorry to dredge up an old thread, but I have been doing a lot of reading on CALs lately in anticipation of launching a public website. Reading the license agreement, I don't think you need CALs on the front end Windows Server 2012 just because people
are authenticating. The Windows Server 2012 license agreement makes no mention of this that I can find. It only says you need CALs for employees or your affiliates' employees. A non-employee visitor does not fall under the definition an affiliate.
The SQL Server licensing is tricky, and not written for public website access. Is every user with an account to your online store need a CAL? The only other option is SQL Server Enterprise licensed by CPU cores.

Manually allocating processor core usage?

Hi all,
So I'm not sure if I'm posting this in the right seciton, but here it goes. So my logic board is broken and Activity Moniter shows that kernel_task (the os itself) is using between 500-600% CPU usage (I have 8 cores so this is about 63-75% CPU capacity)
For reasons I won't get into, I can't fix my computer for about a month. However, there are some higher-performance things I still would like to do. For example, play Dwarf Fortress. Now Dwarf Fortress is not multithreaded, so in theory, if the crazy-high kernel_task usage is restricted to 6 cores, and I can somehow guarentee that 1 core is mostly dedicated to Dwarf Fortress, then I could still play it to a degree. (It's possible that slowdown due thrashing and multi-core issues makes this impossible, but I'm not sure).
Is there some way I can run the program giving it precedence to one of the cores? Or on the other side, restrict kernel_task to the first 6 cores? I'm pretty sure the program itself has no mechanism for this, so it would have to be something from the mac side. I thought maybe virtualizing a machine and dedicating the cores to that machine might work, but the overhead might make the whole thing slower. I'm a technical user, so any suggestions are welcome.

kernel_task does not randomly use 600% CPU. Something is definitely wrong here.
I don't know that you can assign a "nice" value to kernel_task to de-prioritize its CPU usage. Some processes you can, but I don't think you can with kernel_task. Better to find out why it's burning CPU.

Usage of more processor cores?

Hi,
my customer has a database running on a node with 4 processors of type EM64T. Now the question is, whether the Oracle process uses all the processors?
Node:
HW - HP ProLiant DL380 G5
OS - MS Windows Server 2003 Standard x64 Edition Version 5.2.3790 SP 2 Build 3790
Processors - 4 x EM64T Family 6 Model 15 Stepping 11 GenuineIntel 2GHz
Memory - 4GB
Database:
Oracle 11+g+R1
Regards,
Martin

Hi Martin,
The number of processors used is more a function of the O/S than Oracle. I'm sure Oracle "optimizes" itself to the number of processors but, ultimately the O/S is the main determining factor. Oracle can balance its threads among available processors by setting the thread affinity but, that just a way of telling the O/S what is best for Oracle. The O/S could ignore it if it wanted to for whatever reason.

HT2434 Can a logic board, RAM, or processor core be compromised if an attacker gains root access?

If an malicious attack on my computer gained root access from a poisoned program (java applet, flash, unix executable) Could that attacker permanently poison my logic board/PRAM-VRAM or have access from the processor if everything else was (scrubbed)??
Someone gained keychain access on day one in the first 10-15 min. while I was setting things up thinking that the apple firewall was on by default. (Former PC user-oops) I was nailed by a vicious email attack-lucky that it only worked on the yahoo side and it was not opened by (mail) on my MBP. I was also nailed by a brutal PDF, Safari, Quicktime attacks while using Snow Leopard (Mid 2010) In OSX LION, someone was constanly changing my password after waiting for me to restore everything. Then it was a directory services hack. This is why I am concerned. I still see strange activity in console.
Thank you for your time! Mac is still enjoyable to use but the popularity has made it a huge target.

RAM is not the issue in a Mac Pro with Xeon processor, unless you get a distinctive kernel panic, machine check. Otherwise, every Read from memory is checked by Hardware and errors are corrected on the fly, with essentially no slowdown. In the Mac Pro silver tower or dark cylinder, Memory problems do not fester undetected.

Page fault is a reference to memory out of bounds (you do not own). It is most often caused by software.
If you remove the hexadecimal addresses from the stack trace as shown above, the list of what extensions were at the "scene of the crime" becomes much more clear. That is why I could see that your external (SCSI architecture) drives were implicated, and thomas_r. could call out the highpoint driver as being involved.

32gig Memory on Macpro 8 Core - How to use it all the memory and processor speed

Hello Everyone,
I was wondering if any of you out there know a way to have my Mac Pro use more of the memory it has. I have 32gig of memory and I would like to have it use more processor power and memory if possible. I am aware you can use the "renice -10 -p PIDNUMBER"
How can I make it use more of the processors and memory my machine has. Ex. Running Photoshop or Final Cut, Imovie etc.

Using the Unix nice command raises the priority of a process, but software will use the amount of memory it needs. You cannot make a program use memory it does not need. Same with processor cores, if software is written to use only one processor or core you cannot make it use more, the software has to be designed for multi-threading to do that.

When does WS2012 R2 need 8 core processor

Hello Community
    Currently I have WS2012 R2 running on a 4 core processor machine.
    Usage is expected to grow in the future.
    When is it recommended to go up to an 8 core processor machine.
    Thank you
    Shabeaut

Hi,
I agree with Darshana.
For windows server 2012 R2, it only has limitation for the processor, which would not be less than 1.4 GHz 64-bit. Processor performance depends not only on the clock frequency of the processor, but also on the number of processor cores and the size of the
processor cache. Increasing the processor cores, you will get better processor performance.

What Do Multi-Core Processors Do?

I posted a thread on this some time ago, and my understanding was that a multi-core processor allowed for computing tasks be performed simultaneously. Rather than one after another, which is what a single-core processor would do. This is often applied within the applications themselves, to increase execution speed. Such applications being multi-threaded applications.
But I've recently learnt that even single core processors can execute code in more than one thread. So in this sense, what extra functionality does having multiple cores give you? Or am I wrong in thinking that single core processors can do this too? I'm trying to weigh up the advantages of buying a Mac Pro over a different model like an iMac.
There's a hole in my understanding somewhere, I just don't know where it is.
Any info appreciated.
Many thanks,
Adam

multi-threading varies by application
Think of the system having reserved rights to 0, some background task(s) to 1, Safari on 2, etc. is one scenerio.
Some but not all or even a lot of apps are truly multi-thread.
Faster processor cores are still more important than how many cores.
one core with hyper-threading can execute two threads, and deliver 20-35% more in performance at the expense of running hotter and using more watts. HT came back in 2009 with Nehalem and Core i-Series.
Dual processor, two cpus, have been around for a long time on Macs back to G4/500DP and dual and quad-core is just more efficient to manufacture and build into systems (dual core Atom or A8's in mobile devices).
Programs that worked without HT sometimes don't work properly with H-T until they are recompiled and optimized properly.
Your real question is what Mac to buy though, and what you actually plan to run and do.
And there are processors for laptops, desktop, towers and more. And all have different performance.
