• 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.

• 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).

• Free version of ESXi 4.1 CPU with 8 cores

  Hello

  I would like some advice on the question of whether the free version of ESXi 4.1 supports servers with 4 CPU core CPU 8, because I find some contradictory documents on some he said supports only 6 core CPU and not 8. Can someone advise or confirm.

  I think the EULA may need to be clarified.  If we ignore free ESXi for awhile, this document - https://www.vmware.com/download/eula/multicore.html - suggests that it's OK to run vSphere Standard for example on processors with 12 cores.   I only give 2 CPUs per physical CPU licenses as each license would cover only 6 of the 12 hearts.  Here is the example that includes the document

  > Example: A customer has already purchased vSphere Enterprise license. Remember that each license of vSphere Enterprise can be deployed on a > processor with up to 6 cores. However, the customer now wants to use these licenses on a newly acquired server with processor with 12 cores. > The client has two options:

  > Upgrade from the company of vSphere vSphere Enterprise Plus license, which provides a right to 12 strands and extra GOLD

  > 2 two vSphere Enterprise licenses for each processor with 12 cores.

  It would not appear that vSphere 6 basic editions are hard coded to ignore carrots on it 6 but rather you must just the correct license in place.  With ESXi free since you can register an unlimited number (99 I think?)  processors and in essense, you have enough licenses processors to double for each physical processor.  It would not be what they want and it can be "fixed" in the future, but I'm not sure it would be a EULA violation vSphere.  The doc covers products 'vSphere '.

  This affect which products VMware?

  > This strategy affects the VMware vSphere products i.e. vSphere Essentials, vSphere Essentials Plus, vSphere Standard, Enterprise vSphere, vSphere > advanced and vSphere Enterprise Plus

  so maybe they need to clarify their position for free ESXi.

• 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!

  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.

• 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.

  If this point of view to the table, I've found metric to the graph view.

  But when we ran the report, values showed n/a, unfortunately. For the cluster option, I can't use superior even to the table view.

  Some can help me pull vFoglight report.

  Virginia Reynaud

  One way to do this easier would be to create an array with the elements you want on it, as the name of the virtual machine, the use of the processor etc... and then you can filter/sort by CPU utilization, memory usage etc. and only have the Top 10 or anything else you like.

• ESXi hypervisor fere CPU limits

  Hi all

  Could someone me if the free version of vmware esxi hypervisor could use all the range of two quadricoeurs xeon processors 6-core CPU?

  I know I can create a VM with only 4 logical processors. But vmware uses my two processor six hearts?

  Virtual machines are limited to 4 vCPUs unless you upgrade to Enterprise Plus.  In this case, you can configure 8 vCPU VMs.

• 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.

• Tecra A9: Cannot enable or disable Multi Core processing in the BIOS

  I have a Tecra A9 and want to swicht out of the Multi Core Processing in the Bios, but it is impossible.

  To the old Bios version (1.50), it has been possible.

  Now I use the most recent (2.10) and I can't move the cursor to this selection.

  The special key strokes?

  If this isn't the case - where can I download the previous version of the bios where this selection is possible?

  Thank you

  Ulli

  Hello

  > Otherwise - where can I download the previous version of the bios where this selection is possible?
  This is not possible because it is always the newest available BIOS can be downloaded.

  With regard to the option in the BIOS.
  Do you mean you are not able to choose this option or you can't change the value?

  Toshiba BIOS:
  Usually the buttons PgUp / PdDn would change the BIOS page. The arrow buttons to select items. SPACE or BkSp can be used to change the values.

  But note; You can only change the value if it s interchangeable. But many options appear in the BIOS but is not editable.

• 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.PDF

  The 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!
