| <h2>Notes</h2> |
| <p> |
| OpenCL allows applications to create a program object using the program source or binary and |
| build appropriate program executables. This allows applications to determine whether they want |
| to use the pre-built offline binary or load and compile the program source and use the executable |
| compiled/linked online as the program executable. This can be very useful as it allows |
| applications to load and build program executables online on its first instance for appropriate |
| OpenCL devices in the system. These executables can now be queried and cached by the |
| application. Future instances of the application launching will no longer need to compile and |
| build the program executables. The cached executables can be read and loaded by the |
| application, which can help significantly reduce the application initialization time. |
