I have a bunch of threads that are doing lots of communication with each other. I would prefer this be lock free.
This needs to be lock free as it has to run in the interrupt handler of an SMP system. I cannot take locks.
I have a question about the following code sample (m_value isn\'t volatile, and every thread runs on a separate processor)
In the following code sample, does the memory barrier in FuncA is required to ensure that the most up-to-date value is read?
Does someone know of a good resource for the implementation (meaning source code) of lock-free usual data types. I\'m thinking of Lists, Queues and so on?

I read somewhere (can\'t find the page anymore) that lock free data structures are more efficient \"for certain workloads\" which seems to imply that sometimes they\'re actually slower or the gain fro
x86 and other architectures provide special atomic instructions (lock, cmpxchg, etc.) that allow you to write \'lock free\' data structures. But as more and more cores are added, it seems as though th
Obviously, atomic operations make sure that different threads don\'t clobber a value. But is this still true across processes, when using shared memory? Even if the processes happen to be scheduled by
