To implement a lock free code for multithreading application I used volatile variables, Theoretically: The volatile keyword is simply used to make sure that all threads see the most updated value of a
I am reading these days about memory fences and barriers as a way to synchronize multithreaded code and avoid code reordering.
In \"C# 4 in a Nutshell\", the a开发者_如何学运维uthor shows that this class can write 0 sometimes without MemoryBarrier, though I can\'t reproduce in my Core2Duo:
My code is simple as below.I f开发者_StackOverflowound rmb and wmb for read and write,but found no general one.lwsync is available on PowerPC,but what is the replacement for x86?Thanks in advance.
I am trying to improve my understanding of memory barriers. Suppose we have a weak memory model and we adapt Dekker\'s algorithm. Is it possible to make it work correctly under the weak memory model b
I read recently about memory barriers and the reordering issue and now I have some confusion about it.
Previously I\'ve written some very simple multithreaded code, and I\'ve always been aware that at any time there could be a context switch right开发者_如何学Python in the middle of what I\'m doing, so
Referring to my earlier question on incompletely constructed objects, I have a second question.As Jon Skeet pointed out, there\'s an implicit memory barrier in the end of a constructor that makes sure

I\'m looking at this bit of text in th开发者_JAVA百科e documentation for Visual C++\'s _ReadWriteBarrier intrinsic:
