.net - Garbage collector performance on different machines -

-

i have large memory consumption .net 2.0 application. ussually gc handles cleaning of memory well. however, have case application installed in 2 different machines, 1 2gb of memory , 1 3gb of memory. in 3gb of memory crashes out of memory exception, while in 2gb nevers fails. .net runtime same in both machines , application installation same. possible when there more memory trigger start grabage collector not raised on time?

the amount of ram has nothing amount of memory available .net program. modern operating systems provide virtual memory. on windows, typical amount of virtual memory available program bit less 2 gigabytes. there's special boot option (/3gb) increases 3 gigabytes, @ cost of taking addressable memory away operating system. doesn't work anymore on modern machines, video card tends eat addressable physical memory. isn't impossible less 2gb because of this.

if machine runs 64-bit operating system you'll close 4 gigabytes if code runs in x86 mode. , oodles of virtual memory in x64 mode, limited maximum size of paging file.

these virtual memory sizes independent of actual amount of ram installed on machine. if have less ram addressable virtual memory space, common 15 years ago, possible invoke so-called 'paging file thrashing'. see operating system trying provide enough available ram honor program's need use virtual memory @ same time. swaps data between ram , paging file. can severely slow down machine, run out of patience before run out of memory.

an outofmemoryexception tells program ran out of addressable virtual memory. typical cause not depleting address space, running out of holes big enough fit object you're trying allocate. virtual memory can become fragmented. sysinterals' vmmap utility can give insight in how virtual memory of program divvied-up.

running out of virtual memory quite difficult deal with, asynchronous exception cannot recover from. exception of doing loading bitmap, kind of object requires lots of (unmanaged) memory , therefore has trouble finding large enough hole. in general, program should never closer using half of available space. that's not difficult, gigabyte lot of memory. when program's needs fundamentally beyond limit must specify 64-bit operating system requirement program. 2 hundred dollar solution.

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.

i have simple application. have button , label in ib. have ibaction onclick calls settext on label. there's outlet label. connected in ib. crashes app first time in simulator. when launch again, sets text. crashes again next time. crashes on actual device. should simple, i'm not sure i'm doing wrong. thanks. in .h file : #import <uikit/uikit.h> @interface untitledviewcontroller : uiviewcontroller { iboutlet uilabel *label; iboutlet uibutton *button; } @property (nonatomic, retain) uilabel *label; -(ibaction) onclick1: (id) sender; @end and in .m: - (ibaction) onclick1: (id) sender { //[label settext:@"hello world!"]; label.text = @"hello world!"; //[button settitle:@"clicked" forstate:uicontrolstatenormal]; } sorry, i'm new site. how crash log , stack? thanks. edit : while answer technically correct, doesn't answer question @ :( sorry < warning - guess > if you're
