I am confused that Microsoft says memory alignment is required for InterlockedExchange however, Intel documentation says that memory alignment is not required for LOCK. Am i missing something, or w...

Is there any way to implement a type of reference whose value can be exchanged with another atomically? In Java we have AtomicReference which can be swapped with a local variable but not with an...

I have some code which must be thread safe whose behavior resembles this: protected long m_RunningValue protected long m_RunningCounter protected object m_Lock = new object(); public long Runni...

I've been using C# for a while, and have recently started working on adding parallelism to a side project of mine. So, according to Microsoft, reads and writes to ints and even floats are atomic I...

I've been reading the answer to a similar question, but I'm still a little confused... Abel had a great answer, but this is the part that I'm unsure about: ...declaring a variable volatile makes...

Disclaimer: My posts are apparently always verbose. If you happen to know the answer to the title question, feel free to just answer it without reading my extended discussion below. The System.T...

I've written a low lock list in C++ on windows 32-bit. I'm getting BIG improvements over using critical sections but I'd like someone to sanity check that what I'm doing is correct and there aren't...

In other words, can I do something with a volatile variable that could not also be solved with a normal variable and the Interlocked class?

Two Windows processes have memory mapped the same shared file. If the file consists of counters, is it appropriate to use the Interlocked* functions (like InterlockedIncrement) to update those coun...

I'm just wondering whether this code that a fellow developer (who has since left) is OK, I think he wanted to avoid putting a lock. Is there a performance difference between this and just using a s...

Win32 api has a set of InterlockedXXX functions to atomically and synchronously manipulate simple variables, however there doesn't seem to be any InterlockedRead function, to simply retrive the val...

While reading about the function InterlockedIncrement I saw the remark that the variable passed must be aligned on a 32-bit boundary. Normally I have seen the code which uses the InterlockedIncreme...
