        <h2>Description</h2>
        <p>
            The OpenCL C programming language implements a subset of the C11 atomics (refer to section 
            7.17 of the C11 specification) and synchronization operations. These operations play a special 
            role in making assignments in one work-item visible to another.
            A synchronization operation on 
            one or more memory locations is either an acquire operation, a release operation, or both an 
            acquire and release operation. (The C11 consume operation is not supported.)
            A synchronization operation without an associated memory 
            location is a fence and can be either an acquire fence, a release fence or both an acquire and 
            release fence. In addition, there are relaxed atomic operations, which are not synchronization 
            operations, and atomic read-modify-write operations which have special characteristics
        </p>
        <p>
            The enumerated type <span class="type">memory_order</span> specifies the detailed regular (non-atomic) memory 
            synchronization operations as defined in section 5.1.2.4 of the C11 specification and may 
            provide for operation ordering. Its enumeration constants are as follows:
