• Allocation of memory - unlimited option resources

  Looking for assistance with a script that will run on all virtual machines and show where the unlimited option is checked/not checked for the allocation of memory resources.  Any help is appreciated.

  Thank you

  You can get a list of virtual machines and the setting of memory resource allocation with:

  Get-VM | `
  Get-VMResourceConfiguration | `
  Select-Object @{N="Name";E={(Get-View $_.vmid).name}},MemLimitMB
  

  If the value of MemLimitMB is - 1, this means unlimited.

• Allocation of memory for a class system (avoid new/delete)

  My plugin has been crashing a lot, but only under Windows. I realized that the culprit is in my code for the creation of a bitmap GDI + drawing.

  The code I use is:

  ...

  Bitmap image * tempImg = NULL;

  try {}

  tempImg = new Bitmap (width, height, bitmap_bytes_per_rowL, PixelFormat32bppPARGB, reinterpret_cast < BYTE * > (bitmap_dataP));

  } catch (A_long & e) {}

  Return PF_Err_OUT_OF_MEMORY;    Assuming that...

  }

  If (tempImg! = NULL) {}

  canvas = Graphics::FromImage (tempImg);

  delete tempImg;

  }

  In this case, bitmap_bytes_per_rowL has been calculated before, and bitmap_dataP refers to the memory correctly allocated (via host_new_handle()) where the drawing will happen. tempImg is an object Bitmap GDI + Windows, that is only used to create the object Graphics "canvas." Once it has achieved its objectives, it will be deleted.

  I'm 99% sure that it is the cause of my crashes. It crashes all the time and it is more likely when the code is compiled in release mode.

  So, I have two options:

  -Allocation of memory for the Bitmap object using host_new_handle (sizeof (Bitmap)), and lock up the handle to get a pointer to my bitmap object. Problem, it is, how to initialize, because I will no longer use the keyword "new"?

  -Create my Graphics 'canvas' object without starting by creating a Bitmap object. That would be my preferred method, but the only other way to create a Graphics object is via an HDC and HWND, neither of which I know how to access and then how do I associate my (real) memory of drawing?

  Thanks for the tips!

  Christian

  what you are looking for is called a 'new place '.

  Bitmap image * somePointer = new (someMemoryAlreadyAllocated) bitmap.

• Allocation of memory in ESXi 3.5 problem

  Hello

  Before I switched to using ESXi 3.5 to host my VM guest, I used VMware Server 1.0.6 to the guest virtual machines. However, I think that

  the VMServer could not allocate correct memory that I specified in the virtual machine settings, for example, I put 3 GB of memory to a guest

  OS, but I found that only 1200 MB of memory was allocated in the ohter handler.

  So I now use ESXi 3.5 to host 3 VMs, ESXi 3.5 host has 8 GB of memory, two of these VMs have the allocation of memory 1 800 MB and 4 GB.

  However, on ESXi console, I found that me, the 'use of memory of comments' are only 450MB and 778 MB only.

  It's really out of my expectation, it seems that the memory on the VMware product management is the same.

  Does anyone know how fix memory use such as ESXi comments will not control the dynamic memory allocation?

  In our case, it is not necessary to adjust the consumption of memory intelligently by ESXi from time to time.

  I have attached some screenshots for your reference to screen and hope that the screens are useful to explain the problem.

  Thank you for your kind attention,

  Raymond

  It is possble to use memory locking of operating system invited in a fixed allowance?

  Is called memory reserve.

  You can do this under settings of the computer virtual (tab "resources") or by using the list of resources.

• allocation of memory for the pointer in the dll

  Hello

  I am very new to LabVIEW and I was struggling with the third scheduled dll long enough. I am able to configure the device (but with a view of the insufficient resources error code), get the number of connected sensors and the ID of the sensor. But I can't receive data between the device and I think it might be the memory allocation problem.

  I use LabVIEW 2015 32-bit on Windows 10.

  This is the documentation provided by the seller, and the apdm_ctx_t seems to be a void pointer based on the API (typedef Sub apdm_ctx_t)

  APDM_EXPORT apdm_ctx_t apdm_ctx_allocate_new_context (void)
  Allocates memory a handful to be used by the libraries of the apdm.
  Returns
  Zero on success, zero otherwise

  Based on a previous post, I set up the return of the function above to be signed pointer size whole. And the following functions will receive this digital context and pass by value.

  In the attached png, the apdm_get_next_record requires a complicated structure. I have to do as a cluster and supply the function node (see figure).

  The sequence of the vi follows the Matlab code provided by the seller. I have no idea why the vi keeps returning the error code: no data received.

  Any thoughts would be great and I can give you more information if necessary. Thank you!

  Looking briefly at the provided code that I don't see glaring errors. Are you really sure that you do not have misinterprete all return as failuree values or maybe something in your actual System Setup prevents you to get the values you expect?

  You haven't really explained what you think you should get and what you get instead. The matlab example only also shows the use of apdm_ctx_autoconfigure_devices_and_accesspoint5() while you use apdm_ctx_autoconfigure_devices_and_accesspoint4() which I guess is not a big problem, as the example of Matlab is that pass an additional parameter to 0 to the function. However this example shows quite how you're supposed to call apdm_ctx_get_next_record() and then calls apdm_exit() to the end as you do anywhere.

  For now, it seems more a problem with the use of the functions of your DLL in the decree that something that should be fixed in nodes of library call to access your DLL and correctly. A suggestion to improve the screw, you have now would be to actually do the appropriate error handling. for now, these functions have nothing to do with the return value of functions. The right way would be to check the documentation and if a function returns or the return parameter can indicate an error for actually cause the error cluster spread a significant error code endorsements. And all functions except those which is intended to release all resources must have a business structure that incoming error, does nothing and doesn't send the error through.

  But don't blindly assume that, since the function 1 return 0, not for a mistake that all other functions are too. Some might actually return the number of resources found or whatever with 0 to indicate an error or no resources.

• allocation of memory for a LStrHandle

  Hello

  I know that this thing about memory allocation and LStrings has been much already posted but I couldn t find the answer to my question.

  Currently I am working with an external code (c ++) and calling a function of vi.

  I want normal c ++ channels:

  (1) declaring normal c ++ string

  (2) conversion c ++ string in a Lstring + pass it as Lstringhandle (this works very well!)

  (3) initialize a Lstrhandle for my result (it would work very well if I knew that the length of the resultant Lstring! but because the application is set to call ANY function of vi I don't know what the function and so I do not know the length of the result string)

  My problem is really basic, but how do I get the actual length of the modified LString?

  Let´s tell my function of vi concatenates 2 strings and returns the result, then the signature of my vi-function should look like this:

  void __cdecl Concat (LstrHandle * string1, LStrHandle * string2, LStrHandle result);

  at some point, so I need to know the length of the result.

  Any ideas?

  (it is important that the strings are Lstrings and they are passed as pointers!)

  I've tried usinig labviews functions of manager, but this won't work for all of the problem this toddler is integrated.

  I appreciate the ideas and help!

  Thank you...

  Hello

  If your function receives the string1 and string2 as input and returns the result, then the first two by reference and by value, it seems quite a bit back.

  Because string1 and string2 are entered, the function is supposed to use, they must be defined and allocated in any case properly by the appellant. But for output handles passed by reference, it is quite valid in LabVIEW since on version 6 to pass a NULL handle and LabVIEW code takes care of allocating a new handle in this case.

  So basically if you declare your function like that when, you create your LabVIEW DLLS:

  void __cdecl Concat (string1, string2 LStrHandle, LStrHandle LStrHandle * result);

  It is quite valid to call this function like this in your C code:

  LStrHandle string1; initialization of a string

  LStrHandle string2; initialization of a string

  Result LStrHandle = NULL;

  Concat (string1, string2, & result);

  and the result will contain a valid string descriptor on successful return.

  If the output parameter is declared by the value, then you obviously can't pass in a NULL handle because the function has no way to return a new handle. Then, you will indeed need to allocate an empty descriptor like this:

  LStrHandle result2 = (LStrHandle) DSNewHClr (sizeof (int32));

  This allocates a handle with the place for the numElm value and initializes it to 0.

• Number of allocations of memory of hexadecimal string

  I am convert a string to a byte array and then converting this array of bytes into a hexadecimal table using the built-in primitive like this

  

  What is the best way for a performance? When I run the DETT I see multiple memory allocations. I think that one for each element of the array. I think it has to do with the point of constraint. Also, it happens only if I connect to the chain of the indicator. If I run this without the indicator chain I don't see not all memory allocations. (Perhaps LabVIEW do not know the code because I don't do anything with the result)

  I just got the DETT and I'm not very sure of how LabVIEW allocates memory. But I do a test by running this code

  

  I see not all memory allocations in the DETT as I do with the number of hexadecimal string.

  
  

• Allocation of memory and CPU

  Guys,

  My question may sound trivial, but I need it to be clear.
  If I allocate a certain amount of RAM and CPU (without reservation) on some VMS, if virtual machines are not fully allocated amount, is used by other virtual machines.
  I am asking that more I VCOPs reports with a lot of oversized VMs and I also I know I must take measures to reduce the overhead of each virtual machine, I need to know if the memory and CPU are shared dynamically in case of needs of other virtual machines.

  Thanks in advance.

  Daniele

  Short answer Yes, if no reservation is defined, resources are allocated dynamically.  In case of contention, actions values will be used for the allocation of resources.  Virtual machines with lots of unused memory are taxed (income tax slowed) and claimed in a balloon.  The important thing is to know what the VM workload is running, and if VMs are memory aid for the contents of the cache, it is to say sql or exchange and these may consider oversized VMs.  Monitor the virtual machine during the period during the normal business cycle and the size of your virtual machines accordingly.

• Win 8 consumer overview allocation of memory

  I installed Win 8 in VM Player 4.0 on a laptop of HP under Win 7 Professional 32-bit with 4 GB of ram. (Yes, I know that Win 7 32 bit can only use 3 GB of ram).

  I initially allocated 2 GB ram (Max recommended) to win 8 and it ran OK, but there seems to be a lot of beating HD (HD swap?) past. I have reset the settings of virtual computer to allocate only 1 GB (recommended) to win 8 and it seemed to work much better. less derouillee and more rapid response when running win 8.

  So the question is: why to win 8 runs faster with less ram?  Is that because it uses only the "excess" 1 GB of ram that does not use Win 7? When I got the 2 GB allocated, he fought with Win 7 for memory space?

  > So the question is: why to win 8 runs faster with less ram?

  This is normal - each VM will go faster if you assign as little RAM if necessary

• Allocation of memory in vmware workstation

  I'm new to vmware.  I have a server I'll test this on.  I have a Server Windows 2008 R2 with 4 GB of memory.  If I install vmware workstation on it and install a virtual machine Windows XP with 1 GB of RAM allocated to it, does this mean that when the virtual machine is running the XP virtual machine has 1 GB of memory to use the host (Windows 2008) system will have 3 GB for himself to use?

  Thanks for any advice in advance.

  If your virtual machine is fully using the 1 GB or RAM, then Yes, you are correct - but remember that Workstation is just an application that runs on your server, so if the virtual machine does not all allocated memory, the application will require all this memory and so you will have more memory available for the physical host.

• Comments XP not recognize new allocation of memory and hard disk size

  I'm under Fusion 3 on a new IMac 21.5 "running 10.6.1 with 8G of RAM with XP SP3 guest.  Just migrated since late 2006 MacBook 2.06 merger to help Mac running migration wizard, then upgraded to Fusion 3.

  Main problem is that when I updated to the size of the hard drive of 40G per 100 G and changed the memory allocation of 2G to 6G, Windows operating system does not change.  Windows reports 3G memory and 40G hard drive.

  Other questions:

  OS (or VMware) is also unstable and crashes, sensitive sentence without indicating CPU heavy and sometimes does not restart, requiring force to leave.  Usually, will run 30-45 minutes before crash. One application I run is Revit 2010 (which is also unstable, has just installed service release 2).

  Tried to install new comments, but get the message "No boot device" - seen a thread for this and create the ISO image.

  David: I can't help you with the RAM, but I had the same problem when I expanded my virtual HD 20 GB to 30 GB.  Windows XP always thought 20GB and called the rest "unallocated space".

  There is a beauty of a freeware program called Easeus Partition Master - http://download.cnet.com/Easeus-Partition-Master-Home-Edition/3000-2248_4-10863346.html?tag=mncol%3bpop&cdlPid=10982635.  Run on the Windows side (at least it worked for XP) and it should show 2 discs.  Highlight the one you want to extend, click on (expand / resize), drag the divider to full size of HD and then 'apply' and he has done the partition in about 5 seconds for me.  Problem solved.

• Allocation of memory the hypervisor

  Hello

  If I have 2 or 3 servers running on a host computer, say a domain controller and a sql server - how much memory should a leave - or rather, not allocated to virtual machines?

  The hypervisor is VMware Esx4i

  If I leave 1 GB, would this be enough?

  Thank you

  ESX(I) may commit too much RAM. If at some point all the VMS ALL wanted their allocated RAM you would have a problem but under the heading of normal memory use fluctuate. ESXi wants a minimum of 2 GB.

• Allocation of memory in Windows Server 2003 Enterprise

  Hello

  I have installed Windows Server 2003 Enterprise Edition x 86 with 4 GB of RAM in a virtual machine running on ESX

  3.5 and the VM shows that 3.75 GB of RAM allocated. He also

  Watch he uses physical address Extension.How is possible to get this server to see the full 4 GB of RAM. RegardsDave

  Short answer is you can't.  It is based on the Intel Architecture.  It depends on the chipset and other factors, but basically the 32-bit operating system has a limitation in the 4 GB limit.  If Intel has planned no people would use this amount of memory in the x 86 original, therefore that the limitation exists.  Missing memory is tied up in video memory and other things that must be less than the limit of 4 GB.

  http://support.Microsoft.com/kb/279151

  SYMPTOMS

  If you use a computer that has more than 4 gigabytes (GB) of memory installed, system, Microsoft System Diagnostics (WinMSD) properties or other system utilities declare a value of memory which is 256 megabytes (MB) less than the total physical memory that is installed.

  Back to top

  CAUSE

  This problem can occur if a server uses the Intel Profusion chipset. In the dead (ROM) computer memory, memory 256 MB high region is reserved for mapped devices in memory of input/output (i/o). The amount of physical memory reserved may increase according to the number of devices of e/s that are installed on the computer. In general, a computer that has 4 gigabytes (GB) of memory real physics looks as if it has 3.84 GB physical memory total.

  The Profusion of Intel is a chipset eight-way symmetric multiple processing which is designed for enterprise-level server programs. It focuses on the power of raw processing and IO high speed performance that are commonly found in servers Dell, Compaq, Hewlett-Packard (HP) and 8-way IBM. The amount of memory consumed can be greater than 256 MB; However, the memory increases by increments of 256 MB.

  ____________________________________________

  "The MacBook Pro Core 2 Duo probably uses the Intel 945 PM chipset, which can physically handle the 4 GB of DDR2 RAM. However, a number of items that should be stored in and what RAM reached 4 GB physical RAM space, there are overlaps. In other words, in a configuration 3 GB of RAM, there is no overlap with the ranges of memory required for some features of the system. However, between 3 and 4 GB system memory tries to occupy space that is already assigned to these functions. For example, the allocation of PCI Express RAM occurs at a place about 3.5 GB of RAM and requires 256 MB of RAM. Thus, the virtual space between 3.75 GB of RAM and 3.5 GB of RAM is occupied by the PCI Express data. In a system with 3 GB of RAM, so nothing is wasted because the space required by PCI Express memory is always between 3.5 and 3.75 GB and installed system RAM does not violate this space. The net result is that at least 3 GB of RAM must be fully accessible, so that installing 4 GB of RAM, ~ 700 MB of RAM is bunk critical system functions, making it not addressable by the system. »

• Allocation of memory to the VM

  I have a Windows 2003 virtual machine with memory following values:

  Memory active: 357MB, granted memory: 2 GB.

  When I look in the Task Manager I see a process uses 1.2 GB of RAM.

  How it is possible to have a process consuming 1.2 GB if Active memory is 357 MB? The VM not the paging memory inside the guest OS.

  What you see in the Task Manager, is the amount of virtual memory is allocated/paid to the process.  This does not mean that memory is very active.  In addition, memory is granted in pieces, and therefore generally a page is marked in memory for the entire piece.  Thus, pieces is awarded under a page are marked.  Thus, memory granted to a process does not always mean memory actively used.
