Function cuFlushGPUDirectRDMAWrites

pub unsafe extern "C" fn cuFlushGPUDirectRDMAWrites(
    target: CUflushGPUDirectRDMAWritesTarget,
    scope: CUflushGPUDirectRDMAWritesScope,
) -> CUresult

\brief Blocks until remote writes are visible to the specified scope

Blocks until GPUDirect RDMA writes to the target context via mappings created through APIs like nvidia_p2p_get_pages (see https://docs.nvidia.com/cuda/gpudirect-rdma for more information), are visible to the specified scope.

If the scope equals or lies within the scope indicated by ::CU_DEVICE_ATTRIBUTE_GPU_DIRECT_RDMA_WRITES_ORDERING, the call will be a no-op and can be safely omitted for performance. This can be determined by comparing the numerical values between the two enums, with smaller scopes having smaller values.

Users may query support for this API via ::CU_DEVICE_ATTRIBUTE_FLUSH_FLUSH_GPU_DIRECT_RDMA_OPTIONS.
