is it atomic for writing a struct to same global memory location in CUDA? -

-

for example:

struct point {     int x,     int y; };

if threads write own point same location in global memory in same time, possible final result point in location has x value of thread , y value of thread b?

this question closely related concurrent writes in same global memory location , is global memory write considered atomic in cuda?

[this answer copied comment should have been answer.]

is possible final result point in location has x value of thread , y value of thread b?

yes. avoid such scenario need write point single atomic value (ie, reinterpret point double or int64 , use atomic set).

this question has answer here: what's mongoose error cast objectid failed value xxx @ path “_id”? 7 answers even though has been asked many times because entity has no valid objectid field. i came across situation objectid set value can casted objectid still error. the schema: var serviceschema = parammongoose.schema({ servicename:{ type: parammongoose.schema.types.objectid , ref: 'servicenames',required:true } }); pseudo code: servicefromdb=new service({servicename:'some name'}); servicefromdb.servicename='000000000000000000000001'; servicefromdb.save(function(paramerror,paramdata){ if(paramerror){ console.log('but but...',servicefromdb,paramerror) } }); the output of code is: but but... { servicename: 000000000000000000000001, _id: 55079a90286f49280364f78b } { [casterror: cast objectid faile...

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...

i have been using method of resizing uibuttons depreciated, , not robust. , other reasons, want sizethatfits work uibuttons. i've read online, i'm not sure if should work (seems working some, not others, difference maybe between style, i'm using custom). here simple test code recreate issue (i put in viewdidload test, shouldn't matter, , real code part of large project): uibutton *btn = [uibutton buttonwithtype:uibuttontypecustom]; [btn settitle:@"this test long title need word wrap more single line when displayed on tiny ipod in portrait view." forstate:uicontrolstatenormal]; btn.titlelabel.linebreakmode = uilinebreakmodewordwrap; // depreciated - nothing replace it? cgrect r = btn.frame; r.origin.x = 0; r.origin.y = 0; r.size.width = 320; r.size.height = [btn.titlelabel.text sizewithfont:btn.titlelabel.font constrainedtosize:cgsizemake(r.size.width,100000) linebreakmode:btn.titlelabel.linebreakmode].height; // returns approx 86 , changes correctly ...
