Function Documentation

void issueClFlushInStream

(

const DeviceStream &

deviceStream

)

Helper function to flush the commands in OpenCL. No-op in other backends.

Based on the section 5.13 of the OpenCL 1.2 spec (section 5.15 in OpenCL 3.0 spec), a flush is needed in the stream after marking an event in it in order to be able to sync with the event from another stream.
