Re: [Pharo-project] out of memory - cog on windows

by Andres Valloud

Yeah, not all operating systems and application environments are the same. What happens when you let a 512mb image loose in an environment where you have 10 images running on a 4gb machine? Ouch. What happens when you let a 2gb image loose in a 1gb machine and you get an infinite recursion bug? Ouch. But, at the same time, a 512mb limit can be useful precisely to prevent an infinite recursion from killing your machine. I hate to brag, but I have been working on memory policies and memory management for quite a while on VisualWorks, and the edge cases do matter a lot. It's not so simple as to "let's just increase the max memory to 4gb". Also, you can recompile your VMs with different settings and what not, but how do you know they will work? Is the compilation environment standardized somewhere so that I can reproduce an "official" VM build if I want?

Re: [Pharo-project] out of memory - cog on windows

by Alain_Rastoul

Apparently, the vm allocates MAX_VIRTUAL_MEMORY and reduces by steps of 128M until it succeeds. so I suppose it could be possible to allocate 2Gb and see how it runs on a 1Gb system and if this is not too much stress for the system (thinking of the pagefile) ? Tudor is your vm a cog or non cog vm ?

Does that mean that there is no way to pass this information as a parameter like we can on Mac? As far as I know you can pass a parameter, but even so, it won't be able to allocate more than 512MB. I can compile the VM for you with this change in 5 minutes. But I am not sure that such simple code would make it work. I think such limit is there because of something. Otherwise, it sounds stupid imposing a limit just because. 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? I don't think so, but start cc'ing the VM mailing list. You'd probably receive more help.

Re: [Pharo-project] out of memory - cog on windows

by Mariano Martinez Peck

Alain: as far as I understood, he cannot even start the image...so he won't be able to open a workspace and evaluate something. 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? just curious.... thanks mariano On Thu, Apr 21, 2011 at 10:36 PM, Alain_Rastoul <alr.dev(a)free.fr> wrote: > Mmm, you are right, in old squeak versions, there was a parameter > -memory: xx (xx inMB) > but I don't know if it is still in use. > > 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 ] ]; > > yourself. > UIManager default > informUserDuring: [:bar | tasks > do: [:block | > bar value: block printString. > [block value] > on: Error > do: [:error | Transcript show: error; > cr]]]. > > Regards > Alain > > "Tudor Girba" <tudor.girba(a)gmail.com> a Ã©crit > dans le message de news: 6AA1F065-3996-433B-AB7C-1640C08D5A7B(a)gmail.com... > Hi, > > Should I to understand that the only way to enable more memory is to > recompile the VM?
