Re: [pocl-devel] Pocl usage

[Benson M. <ben...@em...>]

Hi,

May want to indicate what platform (operating system and chip) you are 
building on as well as the error messages you get.

OpenCL optimizations are not always portable.  Most people have focused 
on portability on different GPUs, but portability for CPU performance 
using POCL is also of interest.
