Given the following simple lock-free linear allocation algorithm I made: I would like to improve it further to be wait-free on the fast path, disca ...
I am considering concurrent multi-producer multi-consumer data structure that has two methods: success = try_put(elem) and success = try_get(&elem ...
If T is a C++ fundamental type, and if std::atomic<T>::is_lock_free() returns true, then is there anything in std::atomic<T> that is wait- ...
On x86, atomic RMW instructions like lock add dword [rdi], 1 are implemented using cache locking on modern CPUs. So a cache line is locked for duratio ...
I have a producer thread that produces objects at a rate that might (temporarily) be too fast for the consumer thread to consume. Therefore, I'd like ...
So, if multiple processes execute FAA, is there any guarantee that this FAA instruction will be executed in a wait-free manner? What if processes that ...
I am reading the docs for spsc_queue and even after reading a bit elsewhere I am not completely convinced about the meaning of "wait-free". What exa ...
I was working on some concurrent programs for the past few weeks and was wondering if there is any tool that can automatically detect what type of pro ...
I am new to multitasking and IPC and I am trying to construct an approach for fast inter process comunication using shared memory( at first I was rese ...
I've been trying to use already written Wait-free queue by Alex Kogan and Erez Petrank taken from here, but faced the problem. I can't understand that ...
To perform lock-free and wait-free lazy initialization I do the following: and it works pretty well except for one thing: if two threads see inst ...
