Are DUAL-CORE computers more quickly during multitasking?

• Error during asynchronous script runing DIAdem of labview on dual core processor

  Need urgent help / advice here!

  A kernel works well... double heart generates error: error in (line: column 17,: 1): error opening object. The currently open object has no subobjects. Forgotten ObjClose?

  The main software built in labview for data acquisition and analysis generates a PDF report at the end of a test, using DIAdem. For this I use the tiara express vi in labview to generate a report of multi page, in which case I use for loop to go through an array of strings for each page. This loop has a registry change too. After each page I run a script to set a few parameters such as linear/log, start/end and line thickness using the DIAdem Connectivity Toolkit. See the script below:

  Call GraphObjOpen("2D-Axis1")
  Call GraphObjOpen ("2DXAxis8_1")
  D2AxisXDivMode = 'linear '.
  D2AxisXScaleType = "start/end of manual.
  D2AxisXBegin = 20
  D2AxisXEnd = 20000
  Call GraphObjClose ("2DXAxis8_1")

  Call GraphObjOpen ("2DYAxis8_1")
  D2AxisYDivMode = 'linear '.
  D2AxisYScaleType = "full automatic".
  D2AxisYBegin = 0
  D2AxisYEnd = 0
  Call GraphObjClose ("2DYAxis8_1")

  C = 1 to CurveNoMax
  If D2CurveObj (c) = "" then exit for ' c
  Call GraphObjOpen (D2CurveObj (c))
  D2CurveLineWidth = 0.75
  Call GraphObjClose (D2CurveObj (c))
  NEXT ' c

  Call GraphObjClose("2D-Axis1")

  There is also a screenshot of the vi: (script file is generated by the Dscript vi and saved on a disk. then the path is passed to the tiara script vi.)

  

  I think it is, after the first page of the report is complete to the second page tiara ALWAYS shows error as shown above. However, on my P4 laptop with single core (without hyperthreading) its works very WELL EVERY TIME with a given number of channels/pages of the report.

  My chain of thought is the ultra-fast dual core is something in parallel, so no waiting for page previous complete or complete his purpose of closing! However, in my loop for, I use a shift as before named register, certainly this kind of loop can be divided on multiple threads of carrots/parallel? because it must wait for the answer from the previous. ! ? ! ? Im running LV 8.6 on WinXP for this project and I don't even think treatment multicore for loops for is included in this version.

  The other thing is... This script allows to launch at the end on the dual core until I added the last part that uses a loop for to get all the lines of the chart to be the thinkness I need. What this loop for the guilty? Can I stop to run on multiple cores/threads? I read a post by saying that there is tiara 8 support multi core. This triggered my doubt

  As always, your comments are most appreciated

  Hi Al,.

  I have a theory, but only you can test.  In your screenshot of the VI, you have the Boolean value of entry for the tiara run with asynchronous Script.vi = TRUE.  My theory is that if you modify this boolean (and all others like him) asynchrous = FALSE, the error will not occur on the multicore computer.  The other thing you could try would be to consolidate all orders report that relate to a REPORT page in a single call to tiara ActiveX.  In the screenshot below, you have at least 2 distinct call of screw DIAdem, so it's at least 2 separate ActiveX calls for a REPORT sheet.

  Here's what I think is happening.  On a multi-core computer, there is the potential for different orders of LV ActiveX tiara to run on different hearts, which can lead to a problem of synchronization on the side of the tiara.  DIAdem 11.x and earlier works exclusively on 1 CPU, so incoming ActiveX controls should be properly sequenced by the tiara ActiveX task list.  Theoretically, tiara must serialize all incoming ActiveX controls (no matter which CPU processed them) in the order that they arrived at the Server ActiveX DIAdem.  The side sending, the execution of LabVIEW data flow should theoretically ensure that all ActiveX applications are sent in the correct order.  But it is theoretically possible that queue processing ActiveX of the operating system cannot send all the ActiveX controls to DIAdem in order that he receive them LabVIEW - IF YOU have SELECTED PROCESSING ASYNCHRONOUS.

  See if these clues help you,

• What drivers are needed for windows 7 recognize a system with 4 processors, dual-core?

  I have a HP ProLiant DL580 G4 with the following CPU specifications:

  Four dual-core processors Intel Xeon 7140 M. All of them identical, but the specifications can be found here

  I'm running Windows 7 ultimate or Windows 7 Enterprise, but the recognition of all the 4 physical processors is a MUST.

  I can run windows on it very well, but he acknowledges that 2 of the 4 physical processors.

  It seems it would be a driver issue, as Device Manager shows two devices having the status of 'unknown '.

  If it is, in fact, a driver problem, does Microsoft have all the drivers available, or shall I seek third party?

  I would appreciate any advice you can offer. Thank you!

  I hope that someone will know better, but (from the search), so it seems that it only supports two:

  "Computers with multiple processors (CPU):
  Commercial servers, workstations and other PC high-end may have multiple physical processors. Windows 7 Professional, Enterprise and integral allow two physical processors, offering the best performance on these computers. Windows 7 Starter, Home Basic and Home Premium edition recognizes only a single physical processor. "

• Can Satellite L300D 21 X receive a CPU upgrade - to dual-core?

  I want to make my laptop more faster to use software for creating games.

  To do this, I need:

  (1) 2 GM RAM - which I know I can upgrade and does not seem to be a problem.

  (2) adequate graphic/video card

  (3) dual Core processor

  or

  (4) a new compatible motherboard

  Is it possible and if yes, what parts are compatible, and can I do that I can't afford a new computer?

  I search google for hours before coming here and there is really no conclusive answers out there anywhere that I can see.

  see you soon

  > Is - it possible and if yes, what parts are compatible, and can I do that I can't afford a new computer?

  You can upgrade the RAM it would not be a big problem.
  You should be able to update the RAM up to 8 GB (2 x 4 GB)
  RAM DDR2 800 Mhz must be compatible.

  Upgrading the graphics card is not possible.

  The new update of motherboard? Well, first you must use the same motherboard made for L300/L300D series due to the layout.
  Second in my opinion it is completely useless since the new motherboard is expensive and would cost between 250-350. Before you spend 300 for the new motherboard, I recommend buying the new notebook

  Upgrade CPU? It is a question of the compatibility of the chipset
  Since the laptop uses an AMD chipset, you can only use AMD processors.
  The laptop seems to be equipped with an AMD Sempron for Notebooks - 40 2 GHz CPU
  If you really want to upgrade the processor, you must use the CPU of the same family

  But even if you want to use the new processor from the same family, there will always be a BIOS compatibility issue.

• Audio Software OR Traktor - freezes for about half a second because of Dual Core

  Hello

  I've been test Native Instruments Traktor DJ Studio 3 and very often the audio timeline would freeze for about half a second and the game continues. I also have a good low latency soundcard PCI card, so that does not these breaks.

  I managed to get rid of this problem by disabling the second processor core in the BIOS setup. However, I don't like the fact that I'll have to do each time that I use Traktor.

  Is it a hardware problem or software? Software that does not use the two hearts should be able to run without problems, but apparently, there are a few interruptions happening that prevent some programs smoothly.

  That's why I'm posting here instead of the forums of NOR.

  Hello

  Why wouldn't be a hardware problem?
  The fact is that the processors with dual core Intel design and it will appear in Device Manager. Also I m sure that Intel will design with double CPU and core more in the future.

  However, I think and I'm sure it's only a software problem. Software developers have overlooked this fact that there could be another type of processors. In my opinion, you must contact the software manufacturing support to clear this problem. Maybe a few updates are available.

  That's all I can suggest.

• AMD turion x 2 dual-core rm-74

  Hello.

  I have a HP Pavilion Dv5 1210ep and CPU (AMD Turion X 2 Dual - Core Mobile RM-74 2.2Gbz) need to be replaced. The problem is that I have trouble to find this processor because I think it has been discontinued. I do not understand the processors who can I use to replace this one and need my laptop with urgency. Please can you help me?

  OK firstly what makes you think that the processor needs to be replaced? Processors to come out once in a blue moon. It is much more common for the defective motherboard and it will often masquerade as a CPU problem.

  If the CPU here is one on ebay:

• My Pentium Dual-Core E5200 showing as Single

  Good to start with my computer information-

  Windows XP
  Home Edition
  Version 2002
  Service Pack 3

  I have a Pentium (r) Dual-Core E5200.

  My Device Manager shows two hearts, but my Task Manager displays only one and my computer is slow massively. I had a problem a month ago and reinstall windows. It took me a week to get installed and working properly. My bios has Multicore multiprocessing (SP?) active. My Manager to design shows my computer (Advanced Configuration and Power Interface (ACPI) PC. I have a second option for Standard PC. I also tried to find other solutions to get it working properly, but it forced me to change my boot.ini file and I have no one. Yes I did all the stuff to show all hidden files and the only one that shows is C:\WINDOWS\pss and is called boot.ini.backup. All the solutions or who need more information help get my processor works properly. I at one point had show as a dual-core in my task manager. That was before resettlement.

  Hello Stephen,

  I have taken note of the fact that you do not have a boot.ini file.

  Windows XP is able to boot without a boot as long as the boot drive is on multi (0) disk (0) rdisk (0) partition (1) \WINDOWS.

  If the machine has a floppy drive, it may be useful to create a boot diskette to try the steps mentioned in the article that you have found-in this way, you can change the boot.ini without fear of being unable to start abruptly.  You will need to create a new boot.ini file by using the following article:

  http://support.Microsoft.com/kb/289022

  You should be able to use the boot.ini file example text with a certain degree of success, there is always a certain amount of trial and error with this.

  This is being done, you can create startup disk that will allow us to experiment with the boot.ini file:

  1 format a diskette on another Windows XP computer with the same service pack.

  2 copy the NTLDR, NTDETECT.COM, and BOOT. INI files on the disk.
  These are placed in C:\ and most likely will be hidden.

  3. you can then use this diskette to a distressed boot.
  Note that you must work with the path of startup in the boot.ini file, until it works.

  Alternatively, you can create this disk of your Windows XP machine until problems arise and make it available as a "just-in-case measure.

  Let us know how it goes.

• Dual Core processor problem

  Hi, I have an Acer Aspire 5720Z computer ultralight laptop with dual core on windows Vista. By a stupid mistake, I stopped him while he was updating software, so now whenever I try to turn it on, the screen goes black and it does not start.

  As it is a dual core, I keep all of my personal information in the D drive (+ photos, docs, etc.), so my question is: if I restore the operating system, are my deleted information even if it is registered in the D drive (not C)?

  I hope you can help me! Thank you

  CR

  Hello

  Dual-core refers to the processor on the motherboard, not to your problem or your disks.

  C: and D: are two partitions on your hard drive Acer; D: as for data on an Acer Acer has a "hidden" recovery partition

  And Yes; If you restore / recover (new) factory settings, you will lose all your data, such as C: and D: are removed and reinstalled like new during the recovery operation.

  Try a system restore to before that the problem using the F8 method (put your Acer in time, NOT again by reinstalling the operating system) in Safe Mode:

• CPU dual core quad core replace on the radiator? Mini Tower Optiplex 755

  Hi, I am currently using a dual core 6850 and I think to buy a quad core. I have a 500W PSU as a spare.

  Can I replace the CPU on a Quad Core without changing the cooling system?

  heinflhs

  Here are the specifications of the replacement PSU part. Are they not better than the original power SUPPLY Dell block?

  This power supply is ATX and not EPS12V

  Better is not the issue.  Dell power supplys 80% efficient are not 70% ATX.  The - 5v rail is a question too although it may cause a fire from the motherboard or damage your system.  Its a dead giveaway that this is a power ensure between 1990 and 2000.

  This current is on track is not negligible. There is a single 12V RAIL on that unit and its maximum is 17A

  EPS 12V units have multiple @ 18 amps 12V rails each.  MAX Power on 12V rails is 264w not 204w

  This unit has much more on the 5V and 3.3V rails at the expense of the independent 12V rails and CPU 4 pin. So not this emergency equipment is not likely to work well or not at all.

  

  Recommended update or replacement is EVGA 750B 1

  

• What happens if there is multi-core or Dual-Core coupling processors to the top with Windows 7 Home Premium?

  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:

  1. Open the Task Manager by right-clicking the taskbar, and then click Start Task Manager.
  2. 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:

  Hope this helps to answer your question!
