Kernel pipeline

I have a pipeline of kernels:


1) kernel A writes data into buffer X

2) buffer X is copied to host via clEnqueueReadBuffer

3) host data is processed, in callback triggered by clEnqueueReadBuffer

repeat above



Buffer X is created with the following flags :




My question:  once clEnqueueReadBuffer is complete (I have an event triggered by CL_COMPLETE), is it safe for kernel A to run again

without overwriting data being processed on the host ?

Or should I process the data on the host before I allow kernel A to run again?


Because I am seeing a bug in my code indicating that it is not safe for kernel A to run until I process the data on the host.
