How to set the processor affinity and memory.

We have explicit recommendations of our application provider to set the processor affinity for one of our virtual machines running their product. However, this process is not quite clear to me despite the available docs. We are company ESXi 5.1 more.

By looking at the tab "resources" for the parameters of the virtual computer you see under CPU:

Actions (I would do that quite high so that it never goes to confront other good?)

Booking

Limit

The requirement is to set aside x cores for the virtual machine while it is never claim to waiting or resource. They would also potentially implement affinity memory related to the same socket for the effectiveness of the NUMA node.

We have a host with 2 8-core processors with 256 GB of memory. I'm not worried about the affinity of memory. This should be as simple as the control that the 'reserve any memory comments' correct?

Is it simpler just set up a pool of resources for cela CPU and memory? The only concern I have is it if the processor uses the same memory channels. We do not want a CPU into a socket using the channel memory of another plug for this virtual machine.

And it's too late to go back to physics for this system.

Eeghads! Just FYI, the processor affinity is almost never what a seller really wants, even if they think they do. I can imagine there are valid use cases, but I spoke with several vendors who recommend this, and they were all wrong.

From what I understand in your summary, the application is sensitive to the latency of the CPU. If the physical compute capacity, actions and reservations will address the latency. Latency is the only reason why they want to set the affinity, or are there others? If there is other, know what they are, because there is a good chance to those who are also invalid reasons. The processor affinity tends to exacerbate the problems you're having with loans time CPU and can often cause latency application MORE CPU than that without it. Yes, you can set up reserves of CPU to address these issues for this particular virtual machine, but you made life more difficult for the CPU scheduler. DRS involved in the loan time CPU, which means she won't necessarily move these other virtual machines on this host, even if they are jointly stop like crazy. While we're on the subject, this virtual machine would need to be excluded from automatic DRS migration, since you cannot vMotion with the processor affinity configured. It also means the virtual machine must be powered whenever his current host goes into maintenance mode.

In any case, verification 'reserve any memory comments' will not affect memory locality. Will just leave all the pages of virtual memory with physical memory pages (another side effect interesting is that creates the virtual machine is no longer a pagefile on the boot). If you REALLY have to set the affinity to the CPU/memory, memory affinity can be set by changing the settings of the VM, the tab "resources", select Advanced Memory, and you can configure NUMBER here. In addition, if you had already seen it, the processor affinity is configured in the tab "resources", under Advanced CPU.

I highly recommend you challenge the seller and ask if reservations CPU are sufficient. The planner of UC is already aware NUMA. VCPUs how they ask, anyway? Unless they want to more than 8, it is unlikely to split the virtual machine.

    I plan to upgrade my OS to El Capitan.  What are the processor speed and memory required for the operating system works well?

    I use a processor 2.3 GHz Intel Core i5 with DDR3 4 GB 1333 MHz memory.

    My last similar attempt on another machine resulted in a very slow computer.

    Thanks, Ron

    Apple says the following:

    General requirements

    • OS X 10.6.8 or later version
    • 2 GB memory
    • 8.8 GB of available storage

    For best performance, I would say not less 4 GB and preferably 8 GB or more.

    Your i5 is well able to support properly.

  • CPU Ready, the processor affinity, and why I don't seem to get the expected performance

    I have a host that is a physical 2 Quad core 2.66 Ghz socket with 10 GB of RAM.  3i ESX 3.5 is installed.  I have only 2 virtual machines on this computer.  Everyone has 4vCPU and 4 GB of RAM.

    When virtual machines are idle and the app is works not only I see low CPU utilization and CPU Ready is a modest 100-200 on each processor.  When the application is not running, the CPU usage rises to about 10,000 MHz as expected.   However, CPU Ready also climbs to 6000-9000ms, which is by FAR more than I expect.

    I have set the processor affinity for one of the virtual machines gets 0-3 and the other 4-7.

    Why CPU ready would be mounted so high?  With only these 2 VM I would expect ready to be almost 0 CPU.

    Remember however each VM has 4 vCPUs with your two virtual machines that you will use all 8 cores as well as the service (which is still running on cpu0) console and vmkernel so there will certainly be contention climb CPU ready time - first question do you really need quad vcpu? You can try a simple vcpu - if you need to start vSMP with dual vcpu virtual - also do NOT set affinity let the vmkernel annex vms approriately

  • ESX3.5 How do you set the processor affinity?

    Hi, runs 3.5 in a cluster DRS HA.  You can set the processor to a virtual computer affinity?  If so, how?

    Thank you

    not sure but if your using the drs and the VM moves his he loses affinity setting, I'll check, but I think that's conducive HA or DRS greays on the affinity option... Please confirm the guy

  • PES 10 times Organizer and editor crash on multi-core hardware. set the processor affinity unique mode fixed

    As I pointed out in thread http://forums.Adobe.com/thread/941128 I found the editor and organizer for PES 10 crash in basic multi environment, I'm WIndows 64 bit, latest updates (including sp1), I had the same problems with Windows 7 32-bit.

    Workaround is to set the affinity to a single processor.  From the Task Manager, select the "processes" tab, find the exe (for example PhotoshopElementsOrganizer), right click, select "set affinity...". "and reduce the number of CPUS selected (checked) for a single.  (Under different versions of Windows specific means vary, but the basic steps are the same).  It doesn't matter what cpu choose you, but if you are the editor and organizer, put it on different processors.

    Pretty much everything these days being multi-core material, my hypothesis is that Adobe test in a virtualized environment and therefore do not discover this type of unreliabillity.  Adobe really need to test their software further exactly the same problem exists in PSE 6, is hardly new to them.

    The solution is in what precedes.

    If Adobe read this, they should take note that a virtualized environment does not provide a decent systems CPU multi-core fidelity emulation.  The ONLY way to test the reliability of an application is on REAL hardware.

    Hello

    I have a PC Compaq laptop CQ56-110us.  Windows 7 says is has 797 MB video memory shared from the main memory of 2 GB.  I want to reduce the use of video memory, i.e. 256MB.  Is this possible?  If yes how.  I would appreciate help with this.

    Thank you

    Don

    Don, welcome to the forum.

    Built-in memory is allocated by the system.  As more video memory is required, is allocated.  There is no way that you can change.

  • How to set the printer online and keep it online in vista?

    I use my laptop with vista on a network.  When I turn on the laptop sometimes printer says offline and I can't connect unless I have reinstall printer.  There is nothing wrong with my printer or a computer.  The problem is vista not reconnected to the printer.  My XP computer connects again everytime.  I read there was a fix for the problem, but can't find it to download.  I'm not sharing of printer, I connect to the printer directly via the wireless network.  The network is fine and sees the vista printer, but does not connect online

    Go to the Control Panel, open Printers, click right your printer, and then click Create a shortcut. The shortcut will be placed on your desktop. Open the printer shortcut and click the printer in the menu and uncheck the use printer offline if it is checked. You can drag to the taskbar where it is no longer accessible and remove a Desktop or keep both.
