Memory model ordering and visibility? http://stackoverflow.com/questions/7461484/memory-model-ordering-and-visibility has implemented c 11 thread and mutex library A fence with memory_order_seq_cst does not enforce immediate visibility to other threads and neither.. ordering constraints are just that ordering constraints. memory_order_seq_cst operations form a total order but there are no restrictions.. headers atomic memory_order.html From what I can tell std memory_order_seq_cst inserts mem barrier while other only enforce ordering of the..
How to use std::atomic efficiently http://stackoverflow.com/questions/8749038/how-to-use-stdatomic-efficiently the compiler optimizations. If you use the default std memory_order_seq_cst then one or both of these operations will incur the synchronization.. but other implementations may choose differently . However memory_order_seq_cst operations are easier to reason about due to the single total..
Concurrency: Atomic and volatile in C++11 memory model http://stackoverflow.com/questions/8819095/concurrency-atomic-and-volatile-in-c11-memory-model return a stale value. The default memory ordering of std memory_order_seq_cst provides a single global total order for all std memory_order_seq_cst.. provides a single global total order for all std memory_order_seq_cst operations across all variables. This doesn't mean that you..
