Detailed Description
The multi-grid cooperative group type.
Represents an inter-device cooperative group type, where the participating threads within the group span across multiple devices, running the (same) kernel on these devices.
- Note
- The multi-grid cooperative group type is implemented on Linux, under development on Microsoft Windows.
