Hi, I've spent today looking into lockless queues. I have a multiple producer, multiple consumer situation. I implemented, for testing, a system using the Interlocked SList thing under Win32 and it doubled the performance of my heavily threaded task based code. Unfortunately, though, I wish to support multiple platforms. Interlockin...
I'm pretty new to lockless data structures, so for an exercise I wrote (What I hope functions as) a bounded lockless deque (No resizing yet, just want to get the base cases working). I'd just like to have some confirmation from people who know what they're doing as to whether I've got the right idea and/or how I might improve this. clas...
I have lockless queues written in C in form of a linked list that contains requests from several threads posted to and handled in a single thread. After a few hours of stress I end up having the last request's next pointer pointing to itself, which creates an endless loop and locks up the handling thread. The application runs (and fails...
I was thinking, is it possible to have a lockless queue when more then one thread is reading or writing? I seen an implementation with a lockless queue that worked with one read and one write thread but never more then one for either. Is it possible? I don't think it is. Can/does anyone want to prove it? ...
Hi, I have some data that is both read and updated by multiple threads. Both reads and writes must be atomic. I was thinking of doing it like this: // Values must be read and updated atomically struct SValues { double a; double b; double c; double d; }; class Test { public: Test() { m_pValues = &m_value...
