How to get OpenCL kernel simulation performance by Altera OpenCL SDK or Quartus II?

Hi,

I can't tell much about cycle accurate timing simulation, but one sure thing is if the workflow in your kernel is data dependent, then it is very hard to get a good performance measurement in advance.

If your kernel is of type NDRange and you activate the resource-driven optimizer, you will get some estimate such as how many work-items are processed per unit of time.

All in all, the best performance measurement I have found is by activating the profiling in your OpenCL code and timing the kernel execution. This, along with the Altera profiler.

I hope this helps.
