Hi Alain,
Thanks. I would indeed be interested in your compiled VM.
Regarding running it on Mac, indeed I can do that, but I will have to wait until next week to get access to the image due to holidays.
Another bit of information is that the image was built and saved without a problem on the same machine where now it does not work anymore.
pass the image to me. i can play with it on windoze.
Cheers, Doru

I thought he was able to start it on a Mac that's why I suggested to this on a Mac and see if memory consumption was reduced. BTW I have rebuild a cog vm with 2Gb ram for MAX_MEMORY and it runs ok on my 1Gb netbook

Doru, if you can evaluate something in a workspace, you may also try SpaceTally new printSpaceAnalysis and then check the STspace.text  that is next to the image. That way you acn see if there are certain classes that have a lot of instances.
Can you evaluate "Smalltalk garbageCollect " and tell me the answer? Â just curious....
thanks

BTW there must be some hanging references in memory and perhaps youd should do some PointerFinder on it. A very handy script I found (on Ramon Leon's blog or elsewhere I don't remember) could help you. You can try it in a workspace and see if it reduces your memory usage (after save and quit) comment unknown or unwanted commands :  | tasks |   tasks := OrderedCollection new         add: [MCFileBasedRepository flushAllCaches];         add: [WARegistry clearAllHandlers];        " add: [SMSqueakMap default clearCaches];"         add: [Smalltalk removeEmptyMessageCategories];         add: [Workspace             allSubInstancesDo: [:each | each setBindings: Dictionary new]];        " add: [Undeclared removeUnreferencedKeys];"        " add: [Categorizer sortAllCategories];"         add: [ODBCConnection cleanAll];         add: [Symbol compactSymbolTable];        " add: [ReleaseBuilderDeveloper new fixObsoleteReferences];"         add: [Smalltalk garbageCollectMost];         add: [Smalltalk garbageCollect ];         add: [Smalltalk garbageCollect ];         add: [Smalltalk garbageCollect ];  add: [EventManager actionMaps keys do: [:each| EventManager releaseActionMapFor: each] ];  add: [Debugger closeAllDebuggers];  add:[Debugger allInstances do: [ :d | d release ] ];

Should I to understand that the only way to enable more memory is to recompile the VM? Does that mean that there is no way to pass this information as a parameter like we can on Mac?
The problem is that I cannot recompile the VM because I have no access to a Windows machine. Is there one available that provides more memory?
Cheers, Doru

Hi Tudor,
There is a constant in sqWin32Alloc.h (platforms\win32\vm) : #define MAX_VIRTUAL_MEMORY 512*1024*1024 you can change it to whatever you want and rebuild the vm, for exzmple give all the available memory less 256 M .
HTH

We have no specific startUp: methods in Moose. In any case, the issue with opening the image does not seem to be related to startUp:.
Is it really true that the Cog VM is limited to 512MB of memory?
Cheers, Doru

Hi again,
I did not say what the problem was :). The problem was that when opening the image on Windows, he got a Space is low message and the image was not usable (see attachment).
That's weird. Does moose have something on the startup list? Â something that can be bothering there?
Not that I know of. Is there a way to check this?
Classes should be registered using Smalltlak addToStartUpList: aClass Then aClass class>>#startUp: is executed at startup. So implementors of #startUp: on Moose classes should give you the answer.

Actually, using exactly the same process some days ago he produced an image of 190MB. This one works just fine on Windows. The only difference between the two is the size of the loaded data.
It would be really bad news if the Windows vm would be so severely limited in terms of memory.
Cheers, Doru
On Mac it worked just fine.
Cheers, Doru

Hi,
I received a question from someone running a 200MB image on Windows using Cog 2361.
If I open the image on Mac, it works just fine. Unfortunately, I do not have a Windows machine around, and I cannot test but I believe it should be solvable by increasing the allocated memory.
On Mac, I would run it with: ./Croquet -memory 1500m
Can anyone help me with the right incantation for Windows?
Cheers, Doru
