2.7.2. Area Report Message for Function Overhead
The area report identifies the amount of logic that the generates for tasks such as dispatching kernels.
Message | Notes |
---|---|
Kernel dispatch logic. | A kernel that includes the max_global_work_dim(0) kernel attribute contains no overhead. As a result, this row is not present in the corresponding area report. |
