OPENCL with AMD EPYC CPU

Hello everyone,

I am currently trying to calculate some magnetic flux with a refined mesh. Therefore, I am using opencl. The thing is that I am now using an AMD CPU (EPYC 96 core). As I am not really used to AMD stuff, I was wondering if it is better to use Intel or PoCL driver. I have seen discussions when some people were using either one or the other.
