Can how many processor cores I use?

Hi all

I have installed a virtual machine with Windows 7 on an ESXi 4 host:

  • I can select up to 8 cores in the settings of virtual machines.

  • ESXi 4 has a vSphere advanced license key.

However, the virtual machine shows only 2 processors with 1 core each. Can I use only two hearts in ESXi4, even if I use a vSphere license?

If so, why I can select up to 8 cores?

Thanks in advance,

Andreas

You can assign the number of vCPUs is determined by the level of license - http://www.vmware.com/products/vsphere/buy/editions_comparison.html, but you must always take into account the comments OS CPU licenses.  Windows see 2 vCPUs as physical processors and so just to use them.  To move, you must use the parameter of cpuid.corePerSocket - http://www.yellow-bricks.com/2009/06/04/per-processor-licenses-for-your-application/.

  • to seal, decide how many processors

    When deciding on your working process, you need to know how many processors you have then 'add two '.

    On Linux:

    cat/proc/cpuinfo | grep processor | WC-l

    8

    This is the "number of processors".

    To get the number of "cores".

    grep "^core id" /proc/cpuinfo | sort -u | wc -l
    4

    To get the number of physical processors "from".

    grep ' ^ physical id "/ proc/cpuinfo | Sort u | WC-l

    1

    So, how many processors we use?

    I would like the best resources to use for a next session updated, and the question of the CPU has always been an area of shade for me...

    As mentioned in the standard recommendation is 2 * #CPU, if you select a value that is too high, you will see reduced yields. You can always test this point with a wide spot to see the difference for yourself.

    There are several other notes on the reduction of the time to patch which may have an impact more important overall. Don't forget to focus on things like the Patch use merge to combine all the patches, use the hot fix was possible to also reduce downtime.

  • How many processors the TimesTen on Exalytics can be used for the operation of 1 request?

    Dear

    I am analyzing the deployment scenario (2 t, 40 processors) Exalytics cluster - two machines.

    After reading the discussions on this forum and a part of the documentation available for my Oracle Partner login information.

    A doubt is:

    When you run SQL against TimesTen.

    To search for and return the data - OBIEE server, the TimesTen will use as many processors in this operation?

    Thank you

    MMB

    TimesTen (11.2.2) currently does not support a parallel query, so a single query will use one processor, but it will still be very fast because of the nature in memory of TimesTen. And you can run 40 these applications simultaneously without overloading the machine.

    Support for a parallel query is in our roadmap for a future version.

  • How many counters should I use at the same time?

    I have the cDAQ-9172 and 9411.

    There is the specification of 9411, 6DI 9411 channels.

    The NOR-DAQmx help tell

    Note  Terminal PFI are available when the unit is installed in the location of a chassis OR cDAQ-9172 or Groove 5 6.

    So, I don't know if this means 9172 has 2 meters can be used simultaneously.

    My question is 9411 6DI channels, it can be used as counters simultaneously?

    I have more device 2 generate frequencies that must be acquired.

    I hope someone here can help me or give me a hint.

    QIA

    Hi, QIA.

    The cDAQ-9172 has 2 counters that can be used simultaneously, and you are right that install your NI 9411 in slot 5 or 6 slot will allow you to access these counters.  6 DI lines on your 9411 may be used to access the entries to each meter.

    I do not know if you say you have more than 2 signals to measure the frequency on. If this is the case, after a little more info about your application (how times do you need to read the frequency?  How many channels?) and we can try to find a good solution.

    Kind regards

  • How many computers (PC, MAC) use my creative cloud

    Hello

    I would like to ask how do I know how many stations now use my CC, I want to know if I can install it on another PC, but do not know if I have already used all the (2 licenses).

    Thank you very much

    You can install it on as many machines as you want.  All of these machines, you can have two of them signed at the same time.  If you try to connect to another, you will receive a notification that you have already two active so that you can disconnect one of the others.

  • How the processor cores and RAM work?

    I'm abit confused as to how work the processor cores and RAM work? What is selecting 2 hearts the mac was still 4 processors and virtualization of Windows is limited to 2 hearts or virtualization of Windows has 2 cores and running the CMA may have 2 hearts ? The same for both RAM and also when is suspended the RAM of virtualization Windows continue to use mac RAM?

    Kind of a newbie question, but I'm new on this and have tried searching on Google and could not find anything on this subject, it was that most do just enough carrots or RAM rather than information.

    Best regards

    -Mark

    Welcome to the community - operating system MAC will always use all the cores by default. Fusion is an application running in the operating system, and when you run a virtual machine and it needs time processor, the operating system will set the virtual CPU on a core - and if you have 2 vcpus assigned it will plan each thread on separate kernel - memory is done in the same way that the virtual machine when it is necessary the OS it will plan to the applicattion.

    When you suspend a VM from virtual machines running it will still use some memory - to suspend the virtual machine, it is better to merge.

  • Adding RAM to an HP Z800 - how many slots should I use?

    I'm about to add more RAM to an HP Z800. The computer has 12 memory slots. Today, I have 12 x 2 GB RAM modules, IE 24 GB of RAM. The processors are 2 x Intel X 5670 (processor-core/6). I have the BIOS version 3.21.

    I want to upgrade to 48GB of RAM and wonder if I should buy 6 @ 8 GB memory strips or fill all 12 slots with 4 GB modules. Both options give me 48GB of RAM. So the question is if I lose any performance using only 6 of the 12 sites of memory and if so about how much? What is the pros and cons with the help of 12 locations compared to the use of only 6 sites while leaving 6 unused when fill a system with the same amount of RAM?

    Intend to purchase Kingston memory, 2 x KTH-PL313K3 / 24G or 4 x KTH-PL313SK3 / 12G.

    Any useful response is appreciated!

    / Roger

    Roger,

    Because the price is not the issue here, they are substantially the same, I would look in the documentation for the HP. Should I use mode memory channel single, double or triple with 6 or 12 slots populated? With 12 slots, you are sure to use the memory in triple mode, with 6 I don't know, but with only 6 slots populated, you have opportunities for expansion in the future.

    There is a definite advantage in the use of 48 more than 24 GB, but is it wise to invest in this memory with your specific mobo and CPU, or wait for the SB-E as an alternative with 32/64 GB of memory, although at much higher prices but with OC-ability, you must decide which.

  • HOW MANY BUTTONS SHOULD I USE IN STILL CS5

    Thank you!

    DANIEL

    The ceiling of button's menu.  So, you could make your menu 25 button in 4:3, but not 16:9.  Easy enough to split the C menu in multiples in a letter of the alphabet.

    Keep in mind that you have a limit of 1 GB for all elements of the menus/movement for the project.

    You also have a limit of 99 chronologies by project in Encore.

    Almost all past and current PC applications are only one processor/heart aware.

    Multi-threading...

    http://en.wikipedia.org/wiki/Multithreading _(computer_architecture)

    This may explain better...

    http://www.Intel.com/content/www/us/en/architecture-and-technology/Hyper-Threading/Hyper-Threading-technology.html

    And this...

    In order to use multiple cores, the Application must be written to do. A unique set of thread on a basic multi computer installed will cause only 1 core used by the game. There is an advantage that the BONE may assign other duties to the idle Lossnay. If the game can have the attention of 1 core. This isn't a bad thing and gives rise to real performance improvements. But because the game itself doesn't "understand" 1, then it will use only 1. It's him you use XP or Vista. Almost all past and current PC applications are only one processor/heart aware. This will change over time, for sure. But in many / most cases, it will require developers to write completely new applications.
