Keep in mind that, depending on how images are loaded, you won't be able to load images larger than about 2gb... you might want to test that. On 7/19/14 13:39 , Tudor Girba wrote:
Wow! I will certainly try this patch.

Well,
I fixed the problem by modifying the Pharo.exe file with the 4GB patch program (http://ntcore.com/4gb_patch.php).
As mentioned before, I think the best solution is that Pharo vms must be compiled with the flag LARGEADDRESSAWARE, so more memory space is enabled for 64bits Windows OSs.
Thanks guys

I worked on that switch before, and IIRC it's just a linker switch that marks executables a certain way. So, if you have imagecfg.exe handy...

Well. It seems that Pharo vms must be compiled with that option :/

Hi,
I'm using Windows 8.1 (update1) 64bits with 4GB of physical RAM. I only need 1.5GB of RAM, so I think I don't need to configure my OS to take /3GB of RAM.
Well my experience (and others) is that one can't grow the heap much above 1.1 Gb without using the /3Gb switch on Windows XP. I can't talk for 8.1. But if 8.x also limits memory to 2Gb/process unless the /3Gb switch is in effect then yes, you'll need to use the /3Gb switch.

Hi guys,
I'm running some experiments in Pharo. My data is aprox. 1.3GB. When I load my image on Mac, everything works perfectly. But, when I try to load the same image on Windows, I get this error:
Unable to commit memory (1326649344 bytes requested)
I tried the Pharo VM, cogMT and NBcog with and without the option
AddressSpaceLimit = 2048
in the ini file
Please help.
What OS are you using? Have you read e.g. http://msdn.microsoft.com/en-__us/library/windows/hardware/__dn613959(v=vs.8... <http://msdn.microsoft.com/en-us/library/windows/hardware/dn613959(v=vs.85).a...>

Here are some additional links...
/LARGEADDRESSAWARE (Handle Large Addresses) http://msdn.microsoft.com/en-__us/library/wz223b1z.aspx <http://msdn.microsoft.com/en-us/library/wz223b1z.aspx>
Memory Limits for Windows and Windows Server Releases http://msdn.microsoft.com/en-__us/library/windows/desktop/__aa366778(v=vs.85... <http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).as...> I learnt something new reading this article. For Win 8.1 64-bit, the /3GB switch is not applicable or required. However the /LARGEADDRESSAWARE linker option is critical for both 32-bit and 64-bit VMs. Its only the default setting that changes between compiling 32-bit or 64-bit applications. Some extracts...
Limits on memory and address space depend on whether the IMAGE_FILE_LARGE_ADDRESS_AWARE value of the LOADED_IMAGE structure and 4-gigabyte tuning (4GT) are in use. IMAGE_FILE_LARGE_ADDRESS_AWARE is set or cleared by using the /LARGEADDRESSAWARE linker option. 4-gigabyte tuning (4GT), also known as application memory tuning, or the /3GB switch, is a technology (**only applicable to 32 bit systems**) that alters the amount of virtual address space available to user mode applications.
On x64-bit MS Windows, User-Mode virtual address space for each 32-bit process 4 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE set 2 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE cleared (default)
On x64-bit MS Windows, User-Mode virtual address space for each 64-bit process 8 TB With IMAGE_FILE_LARGE_ADDRESS_AWARE set (default): 2 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE cleared
