This implementation does not use locking or condition variables internally; it's purely based on atomics and futexes. Notably, concurrent sem_wait() and sem_post() calls can run *completely in parallel* without slowing each other down, as long as there are empty slots for them all to succeed without blocking. Additionally, sem_wait() never executes an atomic operation with release ordering, and sem_post() never executes an atomic operation with acquire ordering (unless you count the syscall). This means the compiler and the hardware are free to reorder code *into* the critical section. |
