Auto-vectorization on the Intel Xeon Phi Coprocessor.

[Sumedh_N_Intel]

Hi, 

Can the Intel SDK for OpenCL applications vectorize only the dimension 0 of the workgroup or can it even vectorize loops present inside the work-items (loops in the kernel itself). I am not sure if I have made the question clear enough. Let me know if you have any questions. 

Thanks,

Sumedh

Hi Sumedh,

Currently, the Intel OpenCL compiler only vectorizes along the dimension zero work-items loop. If you have a real life example in which you think that vectorizing other loop would yield better performance, then please share it here (or privately). We would like to analyze such cases.

Thanks,

Arik
