I\'m new to using gcc inline assembly, and was wondering if, on an x86 multi-core machine, a spinlock (without race conditions) could be implemented as (using AT&T syntax):
I load image by NSOparationInvokation and call out method in the main thread, which adds this image to scroll view, but app hardly lags. If I load image but not add it view,开发者_如何学JAVA app works
I had a look at the concurrent col开发者_运维知识库lections but they appear to use normal locking underneath the hood. Are there any good examples in the .Net framework that use this locking construct
I think both are doing the same job,how do you decide开发者_高级运维 which one to use for synchronization?The Theory
I\'m currently working on a cross-platform task scheduler, but I\'m having a problem with sem_wait spinning while waiting for the semaphore. On Windows, I\'m using WaitForSingleObject, which yields th
Using .NET reflector, I find that the SpinLock structure has a lot of cases where it calls Thread.BeginCriticalRegion and doesn\'t call Thread.EndCriticalRegion.
Having been reading through Understanding the Linu开发者_如何学Gox kernel (Bovet & Cesati), the chapter on Kernel Synchronisation states that the spin lock acquisition code boils down to:
consider a program with optimal thread count running on dedicated server, so if one thread is locked there\'re no others (almost) waiting for 开发者_Python百科CPU time. does spin lock provide better p
I\'ve recently read section 5.5.2 (Spinlocks and Atomic Context) of LDDv3 book: Avoiding sleep while holding a lock can be more difficult; many kernel functions can sleep, and this behavior is not a
Check My Understanding of semaphores, please! I understand the idea behind counting semaphores and bina开发者_运维问答ry semaphores. However the difference between a spinlock and semaphore implement
