Detailed Description

Scope for atomic and fence operations with system-wide visibility.

When used with atomic operations, all threads in the system (potentially across multiple devices) will see the updated value. When used with threadFence, it ensures that all writes from the current thread are visible to all other threads in the system.

Attention

System operations are only visible to other threads of the same device kind. Operations executed on a host compute device will not be visible to threads in, for example, CUDA/HIP or oneAPI kernels, and vice versa.

Note

This is the strongest scope, analogous to CUDA's atomicAdd_system and the strongest fence.
