Allocation of memory to the VM

• 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 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!

• Allocation of memory consumes items regarding the generations

  Hello
  
  I am trying to understand how the GC and VJM address allocation and GC of large objects. I strive to be able to do the following:
  
  1 start with a small lot size
  2 allocate large object-> results by increasing the size of the heap
  3 stop using large object
  4 run GC and ultimately without the large object and also reduction of the size of the heap
  5 you end up with a size of small piles
  
  To achieve the above, I'm trying to get the object to be allocated to the part of the younger generation.
  
  a. However, although I put the - XX: MaxNewSize = to a value greater than the size of the object, based on - verbose: gc output, the object is given in the part of the generation tenure, and after GCed, the size of the heap does not decrease.
  b. If I put the value-XX: NewSize = to a value larger than the size of the object, and then based on - verbose: gc output, the object is indeed attributed to the part of the younger generation. However, the heap is not diminished after GCing of the object, because it is the minimum size is set to a value too large.
  
  Y at - it a bug in the behavior above - especially in one. ? Given that - XX: MaxNewSize = is greater than the size of the object, the virtual machine to increase the size of the part, rather than to assign the object as a Professor, I would have expected.
  
  I was also wondering if there is another way to get the desired behavior.
  
  Best wishes
  Firas.

  Although largely correct, a common misconception is that this will result in memory "rejection" to the BONE. This is not the case. Actually virtual memory is allocated to the JVM on start up (to maximum size) however that this memory is used allocate pages of real memory to the JVM. When you reduce consumption, "free" memory reported by the operating system will not change. The virtual memory of the application has not changed and the real memory will be released to other applications if they require it (your memory "liberated" may be reversed on the disk that will be a big hit to your application if you need it again)

  a. However, although I put the - XX: MaxNewSize = to a value greater than the size of the object, based on - verbose: gc output, the object is given in the part of the generation tenure, and after GCed, the size of the heap does not decrease.

  You should see the amount of free memory in the increase of the jVM.

  Y at - it a bug in the behavior above - especially in one. ?

  No, the JAVA virtual machine has always worked this way as it is the number of channels C works.

  Given that - XX: MaxNewSize = is greater than the size of the object, the virtual machine to increase the size of the part, rather than to assign the object as a Professor, I would have expected.

  He will place always large objects in space holds no matter how big the NewSize is. BTW: the new size is the sum of the eden and the spaces of two survivors. You need the new size large enough to make the free eden is superior to your object until it had a chance (or decrease your ratio of survivor)

  I was also wondering if there is another way to get the desired behavior.

  My suggestion would be to not allocate and release the large objects repeatedly. If possible, recycle and reuse large objects so they are created once at startup.

• Use of memory in the guest virtual machines

  Hello

  I don't have any background on VMware technology, but we are using a facility of dynamic cloud based on vCloud Director to the company where I work.

  The group that operates the server publishes the offer with a 'pay per use model"of service.

  This is true for the CPU resources, as we pay only what we use in the month. But in my opinion, it does not for the use of the RAM.

  We have Linux VMs that allocate a 4 GB of RAM 'physical' and our monthly bills show that the RAM usage is at 100% for all the month. But when you look at the tools of memory for the virtual machine, you can see that most of the time 50% or even less is used by the guest operating system process.

  This means from a user perspective the RAM price per month should be half of what we are responsible now. Ask operators on the 'question', we always get the answer that the use of the RAM is not dynamic and we need to pay for the use of 100% from the point of view of the server host.

  Could someone share some light on this subject? Is there really no way to make use of the dynamic RAM as the CPU usage?

  Thank you

  Michael

  Evening,

  As a service provider, I'll let you in on the secret:

  It depends on

  vCloud takes care of three models of default allocation.  Your provide may use other

  -Pay for what you use. -pay as you use

  -Allowance - you get resources, but can burst more

  -Booking - you get allocated resources and is

  Chargeback depends on model (in out of the box chargeback... your provider might have something custom)

  Pay as you use - charged on the basis of the resources used

  Allowance - remuneration based on allocation and additional for burst

  Allocate pay based on booking-

  There in the last two models really no way to load except full allowance (i.e. 100% cpu and RAM)

  Statement, I think you have something along the lines of the compensation you are using you mixed with a price system vendor.

  From my experience the resource more used in ESXi clusters in the RAM.  That's really what I buy in clusters of resource... I always need more RAM.  I need no more CPU. In addition, distribution of the CPU to vcloud is made via Ghz is not CPU.   RAM is allocated by GB.   So those set up and I think you suppliers is betting that they will always have to RAM so they charge based on usage not allocation.  While CPU, they have tons while they charge by usage.

  Really, it's just my thoughts... What can charge you on:

  -Ghz processor

  -GB of RAM

  -GB of storage

  How can recharge you:

  -Used

  -Allocated

  So bottom line... they can charge by opportunity they choose not too...

  It will be useful,

• recommendation of the memory for the guest operating system

  Hi guys,.

  I need some advice

  I have a pile of vsphere 5 made of 2 servers on each server that I have on 5 VM

  (1) domain contoller 2008 standard edition + dhcp + dns

  2) exchange 2010

  (3) file server

  (4) primavera

  My question is what is the recommended memory and cpu for these VM configuration? I'm a bit confused

  What happens if I don't set up the limits and booking hotel and leave all default? What is the point of the week in this configuration? If I leave all default each VM does not use memory a cpu as it needs?

  Thank you specify in advance

  To add the tips of memory... Many people allocates memory for the virtual machines that will never be used, and ultimately you consume the memory of your host much faster than necessary. Start low when allocating memory to a virtual computer. Adding memory is simple to make, after you have collected on the functioning of your host performance data. The Performance tab will show you what is happening.

• Question about the use of the memory of the host and the VM memory limit.

  Well, I have so vCenter PAHO running in my environment.  My host started to have a little low on available memory and the server of the OPs was the biggest pig, so I thought I could try to corral it a little.  Here is some info documents and help than I thought.

  ESX host has pointed out, looking at the level of the ops vc server:

  Host of Mem - MB: 7364

  Guest member - %: 3

  With the virtual machine has highlighted:

  Consommé of host MB memory: 7378

  Client active memory: 573 MB

  So I understand these numbers as such: the memory of the host is the amount of physical memory that has been allocated to the vm, and the memory of comments is the amount of memory allocated is really active in the guest operating system being used by the process.  Please correct me if I'm wrong.

  My solution was to set a limit on this virtual machine with 4 GB of memory, freeing up about 3 GB of memory to the host, but after the change is made, consumed host memory never came down.

  What Miss me?  Thanks in advance for the help.

  I understand that. Can you turn off this guy and turn on the power?

• 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.

• CC of Photoshop-&gt; performance down, use of memory to the top.

  I've recently switched to Photoshop CC.

  I noticed the performance was slow, memory usage has been huge. At first I thought it would be because I'm a little bit bigger than the previous panoramas processing (e.g. merger of 25 images at 21 Mpx each).

  Then my SSD drive crashed when the sysem ran out of memory, and I can't get it back.

  I reinstalled Mac OSX 10.7.5 on the original HD and re-installed PS now, my bandwidth jumped below 1 GB downloaded per day, at 20 GB, 30 GB, 44 GB downloaded.

  I don't know how this can be traced to CC PS, other than to slow performance and high memory usage, but it ' a coincidence is suspected.

  Tom Legrady

  That would be because the memory usage is the same as previous versions, and we know not all major leaks memory in Photoshop CC (we do a lot of testing to find and eliminate memory leaks in Photoshop).

  And because we have seen third-party drivers and third party plugins with memory leaks.

  If Photoshop is consuming that amount of RAM without opening documents - so you have about 6 GB of presets being loaded at the launch (which is predefined settings that you have added, because by default Photoshop doesn't load that many presets and consumes less than 300 Meg to the launch).

  If you mean Photoshop costume that much after the closing documents - then this is how you allocated to Photoshop and used in your documents.  Photoshop does not free memory in the system until the output is perfectly normal behavior (otherwise it would be much more slowly).

  We can try to help you determine which consumes memory on your system.

  But by emphasizing the fact that Photoshop is the cause, when it is easily verified as not the cause, will not help you.

• 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 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. »

• the memory of the VM concept

  in the summary of a virtual computer, we can see three memory settings, for example: memory overhead(99MB), memory usage(72MB), memory usage(564MB) host comment, what is the meaning of them?

  Explanation of the Dragon is about right. There are a lot of technical details which are difficult to transmit through the forums, it would be nice if someone put together a little demonstration flash of operating memory allocation & free lists, balloning, pinning, etc.. There was a demonstration of fantastic at VMworld 08, session TA1401, "Understanding host" and Guest memory usage and other memory Management Concepts by Kit Colbert. He did a great job explaining the relationship between the virtual memory (app), the physical memory (os) and the machine (vmm) memory... How the pages are allocated and followed everyone later... etc.

• A question of memory to the VM

  Hello

  What is the difference between "Memory usage" and "Active memory" of a virtual computer?

  Concerning

  What is the difference between "Memory usage" and "Active memory" of a virtual computer?

  Memory usage is the amount of memory claimed by the virtual machine to the host.  Active memory is the actively used by the guest operating system.  Active is detected by VM Ware as memory used by running programs and use global memory allocated.
