Multi-core cpu support
VCenter 4.0 U2 running. We invited W2K3 and W2K8 Standard and Enterprise. Confused about licensing and the use of CPU sockets. carrots and vCPUs. Want to change a system file Windows feedback .vmx to allow more cores are available for some gustes. For example, on a W2K8 R2 Std guest, we were able to establish 8 vCPUs via vCenter. We would use more if possible. Each socket has 12 cores. Can we change the config of comments to use 12 instead of 8 vCPUs. Is there a performance improvement if possible. THX.
Then vCPUs are the processor cores, and they directly affect the number of sockets in the Microsoft world. 4 vCPUs is 4 shots. 8 vCPUs is 8.
By default.
However, its possbile (easily) to adjust the way in which the VM views these nuclei. By default, each = socket base, but with a simple change, you can consider them as a single socket with 8 cores (within the virtual machine).

Multi-core CPU: this is an important factor?
Hello
I guess the CPU multi-core is probably important. But is there a rule or guidelines? I would be grateful any entry about the experience of the use of multi-core processors in a virtual machine (as a workstation or server) environment. In all the scenarios below, we assume that the memory sharp and e/s disk are satisfactory. I would like to isolate the factor of the CPU.
Q1. A two CPU cores is equivalent to two physical CPU core?
Q2. Number of vs. frequency of the processor cores: which is more important to run VM? Example: 2 hearts to hearts vs 4 3 GHz to 2.33 GHz
Q3. How is the "engine" of the virtual machine using muti-core with regard to the number of virtual machines running? Is it true to say more "better cores?
Example 1: host has 4 cores of CPU 1, 2 running virtual machines (what a waste of CPU resources?)
Example2: host has 4 cores of the processor 1, 6 running virtual machines
Q4. (Phenom2, Core 2, Xeon, i7) CPU architecture: the "engine" of the VM uses these CPU everything too, or is there someone who is particularly well suited for running virtual machines?
Thanks in advance for any help.
Q1 - Yes - ESX/ESXi treat each heart as a logical processor and plan virtual processors to these logical processors
T2 - both are important - the vmkernel treats views CPU as a pool of cycles - 4 2.33 GHz is a pool of 9,32 GHz while 2 x 3 GHz is a pool of 6 GHz so as long as a virtual CPU has not a complete CPU - a virtual CPU can run on one heart at a time, so a 3 GHz core will be able to provide 3 GHz to a virtual computer
Q3 - Yes more cores is better - the 'VM engine' called the vmkernel will plan the virtual machines between all hearts - VMware recommended 4 to 8 virtual processors per core according to load - so a single quad core cpu can support 16 to 32 virtual processors according to the load
Q4 - he use them all as well - it will benefit from new technology of virtualization being in current technology chips.

The host VMware workstation and multi-core CPU
Apologies if this has already been answered, but all my research to turn questions about processors how can specify in a virtual machine. It's not what I'm after here.
I want to know is the use of VMware workstation (v6 and v7) is available on a multi-core worksation host physical cores.
I have a scenario where we have several virtual machines containing sensitive coding environments. The material that they are on is a little old and we don't have the time or the knowledge to recreate systems (a combination of Matlab, DSpace and some custom coding). Our only option (and we did it for a couple with success so far) is to create virtual machines of these workstations.
Which is absolutely essential for us is the material we choose VMs on host. Virtual machines will use simple/double/processors virtual.
In order to choose the correct hardware platform, I need to know if VMware workstation is running an instance of the virtual computer within a single processor (in this case is the reduced performace?), or if there are multithreaded and make the most of the hardware it will run on.
(We are not welcome, never more 2 virtual machines at the same time)
Any suggestions on material would be appreciated also. I think of something based around a core of Xeon 4-6 with 12-16 GB of RAM.
Thank you very much
Nick
Correct, for laboratory/debugging and interaction VM Workstation is pretty good.

In ESXi multi-core CPU utilization
We have a Dell R710 ESXi server. The server has dual processors core quad xeon 5620 which are estimated at 2.4 Ghz. In vsphere client summary to the server of the CPU is reported as 8 x 2,393 Ghz processors. Is this correct? This would lead me to believe that I have about 19Ghz of cpu resources. However, I feel that even if a quad core processor has 4 separate cores, they operate only at a combined max 2.4 Ghz (with this processor for example). Could someone please shed some light on this subject? I would greatly appreciate it.

No, a quad-core 2.4 GHz processor has four "cores" capable of executing code in every 2.4 Ghz each.

Hey guys
I'm looking for a little clarification on an issue with parrell treatment in LabView. If I have a dual processor with two 4 core CPU computer will be able to access all 8 cores in the LabView environment. I presume he can use carrots that can see the operating system?
Thanks for the help,
Tom
Norbert B has written:
It is the work of the operating system that applications may use all of the hearts, if necessary. So for the application itself, it should make no difference if the system (hardware) is MultiCPU, multicore, or even simply Hyperthreaded...
Norbert
It's true, but I would like to add my 5 cents here.
Lets say, if you have a simple loop like
While (true) {}
do something
}
then OS will get a chance to run in multiple threads. So you get max 12.5% CPU load to 8 core PC or 50% max on dual core PC.
I have dual core PC now and allows to check:
Thus, as we can see - 50% CPU load reached (a single core charge more, but its a different story).
Well, if we are going to use two while loops, then we will get 100% load:
Of course, if you need to load all 8 cores, you should have 8 parallel loops.
Compare BD above with the following:
We have two functions of minmax table and they independently, but we have only 50%.
Well, you can get also the 100% CPU utulization inside while loop. In th example below, you have two sub - VI, who called in the same loop:
Here we have 100%. Important, these screws must be reenterant!
See what happened if they reeenterant not:
Now a little about the Vision. Most of the SubVIs Vision behind are DLL calls. Some features of Vision already optimized for the multicore performance. For example, the convolution:
On the comic above, we have a simple loop with a Subvi, but two cores are used (convolute itself already optimized for the core multi car).
Remember, not all functions of Vision optimized yet. For example, low-pass still single-threaded (compare this BD BD above):
Of course, we can use multi hearts - just perform a parallel execution (you must split the image for both parties, and then to unite and so on):
Remember, SubVIs must be reeentrant, and all calls DLL must be thred safe (not in the UI thread). Also good idea to stop debugging in such experiences to eliminate the additional CPU load.
Another point on 8 cores. As far as I know, LabVIEW (and application on LabVIEW) will support only 4 cores within a default delivery system (at least before LabVIEW 2009). If you have need for all 8 cores, then you must add a few lines in LabVIEW.ini. See the thread next where you can find more details:
Interpolate 1 d slow on computer 8 hearts
Hope that everything written above was correct.
Thanks for reading and best regards.

NB100 - multi-core of BIOS settings & battery discharge while off
Hello, I bought the N100-R there are several monts. The unit is very reliable, but when taking take a closer look at the settings of the bios a few days ago I noticed that the multi-core enabled, while the processor is a single-core. After turning off I found that the drive produces some frequent hickups so intense, that the cursor starts jumping.
Overall performance seems to be less catchy with multi-core disabled.
The logs say nothing about the problem of hard drive, so I made a recovery today including about 168 updates in a row (as a nice side effect the update manager seem to be able to find the files of package again, which was not the case for two weeks or more).
My question is, why the multi-core is enabled on a machine simple heart?The biggest problem is the issue of discharge while the device is in standby mode or even turned off.
Some entries to mention this issue recommending upgrades the core among others), and I wonder if Toshiba is about to face in the near future.
Here, even once, I played with the settings of the bios and disabled option wake-up-on-lan, such as recommended, however nothing has changed.
Thanks in advance.Although single-core CPU, I thought they were hyperthreading (with what looks like two hearts to the BONE). In this case I guess that this setting disables hyperthreading?
168 updates? What is the first set of updates never applied? Sounds like a lot!

Re: Qosmio G50-10 t: How can I use the Quad - Core CPU Toshiba HD?
Hello.
And how you can use several Toshiba Quad Core HD processor with four RISC SIMD 128-bit processors in the Qosmio G50-10 t except that: enables support for H.264 encoders / HD / MPEG2 decoders, with functions for convert, transcode, navigate using the face (Face Navigation) detection and control actions. INJURY is not used!
Maybe someone knows some software sales in which it could be used.
Hello
This Quad Core CPU is an additional processor that is not always in use.
It was designed in the order using the main processor in some of the media process.
For example, the Quad Core CPU works during the encoding or decoding of certain video standards. If you want to change it the standard of the video, the Quad Core CPU helps you complete this quick procedure.In addition, it improves the quality of the video (not HD). So, theoretically, you can view the videos in HD quality.
Of course, you won't get the same quality as a film that has been recorded in full HD, but the Quad Core helps you improve the 576i pictures. -
Can satellite U400 - I switch to a quad core CPU?
Hello
I recently bought a Satellite U400, and I was wondering if I could move the CPU on a quad core processor.
* is it physically possible? that is, fit the plug? It seems that the Q9xxx and the T5750 share the same socket but maybe he ore other parameters to look for.
* How can I check if the motherboard supports the Q9xxx? I should probably need a BIOS upgrade: what is the difference between a win32 and win64 bios? I could guess that has something to do with the target OS, but should I assume that the "win64" adapts to any OS 64-bit-ready (i.e. linux, * bsd)?
* are there significant losses in the battery life?
Thanks in advance> in any case, is there a way to check if the BIOS / motherboard supports a quad core CPU?
You will not find any information about the BIOS and CPU support on Toshiba pages.
The BIOS has been designed the U400 and CPU that is equipped with the U400 series.I put t know which chipset your U400 is compatible but my U400 supports Intel GM965 chipset, and the Intel GM965 supports the same features as Intel PM965 chipset.
http://www.Intel.com/assets/PDF/datasheet/316273.PDFThe Intel PM965 chipset supports the processor Intel Core 2 Duo Mobile for Mobile Intel 965 express chipset family.
The Quad core CPU is not mentioned. So, it seems that these processors are not supported!Cheers mate

LabVIEW 8.6.1 AMD Multi Core Crash with call loops
Hi all
I tried, but I couldn't find all the messages with my exact situation. Here it goes:
I have a multi-core AMD Phenom 64 processor and I'm running Windows 7 64 and I am running an application in LabVIEW 8.6.1 in compatibility mode. (I know, not a good idea) I have a pretty complex application with several timed loops and the different ways to talk to FieldPoint (FieldPoint 6.0.6 and experimentation with Modbus talk to cFP-180 x). You may be wondering why I'm using call loops. It is an application of RT which can also run on Windows using structures conditional disable, etc.
I had met sporadic crashing earlier in my files executable for more than a year and used a lvalarms.dll in only patched version my executables. It was on a totally different processor and we were running Vista at that time. Now, I notice a very similar behavior on 8.6.1, except now the development environment all crashes or breaks down my executable compiled as well.
I found this KB, but he was referring to problems observed on LabVIEW 8.5, and the utility of the OS is only for Windows XP. As recommended in the KB, I used BCDEdit to set the flag onecpu and now everything seems to work normally. My PC is now significantly slower, however, and I wonder if there is another workaround solution that I might be able to try.
If you have read so far and who have followed my description you already have my gratitude. If anyone else has experienced this? Someone at - it ideas?
Thank you very much
Jim
Alright. In case someone else runs into this apparently dark scenario, here's workaround solutions I've found:
1. see if the problem goes away by setting the processor affinity using the Task Manager. Open the Task Manager, look under the "Processes" tab and right-click on the process. (for example LabVIEW.exe or your executable) Under the context menu which select "set affinity...". "and select only the CPU 0. In my case, I have a quad-core processor, so I up to four logical processors that are displayed in the dialog box that results.
Run your application code or the executable file for a while, and if everything seems to be stable, it would seem that you have isolated the problem successfully.
2. one of the solutions is to disable additional logical processors for the entire operating system, although there may be negative implications on performance. In this case, try the steps in the lower part of this KB. I have Windows 7, so I used the utility of command-line bcdedit with no problems.
3. Finally, a really interesting option that is well worked for me should automatically set the affinity of the processor for each individual process. There is at least a utility available to achieve this. I've now changed my LabVIEW 8.6 shortcut to call RunFirst, which sets the processor affinity for LabVIEW to automatically use the first logical processor. This way I can still use my processor image for all it's worth except in applications that have problems with it.
I hope this helps someone else out there one day.

I have problems running games on new computer (and some older) on vista 64-bit. Either the game starts to slow down and "jump" a bit, until she (usually) suddenly freezes (also sound), while single force-rotation - in the distance, the computer is the option. Another time a game just leaves for windows where a message arrives "is a problem and the program must be closed. Is this a classic vista problem? The computer is multi-core. Should I upgrade to Win7?
Hi Mhusoy,
Welcome to the Microsoft Answers site!
You have installed the latest drivers for the graphics card?
Is - what your computer crashes alone while you play games or of otherwise?
You can if check if the games you try playing are compatible with Windows Vista or not. Follow the link and check the details.
http://www.Microsoft.com/Windows/compatibility/Windows-Vista/default.aspx
You try to install the games you play in Windows XP mode and check if you get the same question.
Run the program compatibility Wizard
- Open the program compatibility Wizard by clicking the Start button, click Control Panel, clicking programs, and then clicking use an older with this version of Windows program.
- Follow the instructions in the wizard.
If you are unable to install a program, insert the installation for the program and, using the wizard disk, navigate to the program setup file, usually called Setup.exe, Install.exe, or something similar. The wizard is not designed to work on programs that have an .msi file name extension.

How can I configure a program to run on only one heart of my multi-core computer?
Hello
I have a multiple basic computer, except a very processor that is only designed to run on one heart program (maybe you have heard of him; Dwarf Fortress. Otherwise, it is not really necessary, but good). Now I wonder, how can I set the program to run only on a single heart, whenever I start it? I have a shortcut on my desktop, so if it is not possible to change the parameters of the program or other stuff like in Windows itself, I don't have the ability to change the shortcut to make it work on a carrot.
Hello Drake1500,
Thank you for using the Microsoft Windows Vista Forums.
Since given as each program/software is configured differently to work on mulit or transformation of a nucleus there is nothing that Vista can do to change that. You need to change something in the formula of the show itself. I enclose a link below which talks about this issue. Please let me know if you have any other questions.

So if I have a Windows7 Home Premium 64 - bit operating system and I use a processor dual core (Intel Dual Core e5300 CPU) are fully compatible or how they work together, given the fact that Windows 7 recognizes that one of the two processors? Playback of the system is expressed in the fact that it has two current processors. Both processors work simultaneously to form a combined data stream is a dormant or they turn on and off opposing to another so that each works half the time? Many scenarios as possible, but I would like to know... the real answer as to what needs to be changed eventually to bring together a system more fluid? My main question is the operating system and the processor may be an incompatibility problem that has not yet been addressed? I can't find any answer in the Center Compatabiity of Windows 7 or anywhere else. Or is the limitation of windows 7 Home Premium and only be able to support an unfounded processor see the fact that there are many systems that are in work today with these components. ?
Hey Randy,
If your system has two separate physical processors (not hearts) and you are running Windows 7 Home Premium, the second processor is completely ignored. It turns on and turn his fans, but it does not all rights for the computer. Windows 7 Home Premium will not take advantage of a single processor.
However, if you have a single physical processor with multiple cores, Windows 7 64-bit will benefit from up to 256 cores. It is very probably the type of machine that you have because it is quite rare to have multiple processors co-location in a workstation computer.
In this scenario, Windows will use two cores for separate tasks. Applications will be evenly distributed between the carrots, unless the application has been written to take advantage of multiple cores. The two hearts are turned on and both are used when the system is running.
You can check if Windows has recognized the two hearts looking Manager of the tasks of your system:
- Open the Task Manager by right-clicking the taskbar, and then click Start Task Manager.
- Click the performance tab.
The top two graphs show how much CPU is used, as well at the moment and for a few minutes. If the CPU usage history graph seems shared, your computer has multiple processors, a single dual-core CPU or both.
Windows 7 system requirements also go in a little more detail on how many windows cores/processors can take in charge:

Intel i5 750 CPU supports FT?
Hi all
The Intel i5 750 processor is not explicitly mentioned in "processors and operating systems that support VMware Fault Tolerance"
I would like to know if it can be classified as 'Intel Xeon based on categories of Microarchitecture Core i7'?
If not, I'm just wondering why the i5 (Clarkdale) is included and the i5 (Lynnfield) is excluded.
In addition, one can explain the difference between "any series processor here may be used" and "each series of processor must be used separately" under the heading "Categories of Microarchitecture Core i7 '? Then a form of processor Nehalem/Lynnfield FT with Westmere/Clarkdale processor?
Kind regards
Terui
Processor Intel i5 750 is not on the HCL for ESX, so it is also not supported with FT.
The statement "each series of processor must be used separately" means that there is no interoperability between the processors on the list. In other words, you cannot use a 36xx with a 56xx, you can have pairs of feet with processors of same exact for this game. We hope to lift this restriction in the future.

Quad Core CPU - how is used by workstation?
I just bought a new machine with a quad core CPU.
I know that Workstation only supports a maximum of two hearts. What I don't know is: what does that mean? That means, that if I would have four virtual machines running...
they all do they share only the first two nuclei of the four cores available?
.or each of them uses a distinct nucleus? (or two hearts arbitrary if I would assign two to a virtual machine)
Please enlighten me!
WhiteKnight wrote:

No, my computer supports a maximum of two virtual processors. All physical hearts are deemed be a CPU for the guest operating system. So if your have four hearts in your application assigned to the guest host and two vCPU it there always uses two cores at one point of time.
