`#include <semaphore.h>`

## Public Member Functions
CUTLASS_HOST_DEVICE | Semaphore (int *lock_, int thread_id)
| Implements a semaphore to wait for a flag to reach a given value. More...
CUTLASS_DEVICE void | fetch ()
| Permit fetching the synchronization mechanism early. More...
CUTLASS_DEVICE int | get_state () const
| Gets the internal state. More...
CUTLASS_DEVICE void | wait (int status=0)
| Waits until the semaphore is equal to the given value. More...
CUTLASS_DEVICE void | release (int status=0)
| Updates the lock with the given result. More...

## Public Attributes
int * | lock
bool | wait_thread
