Will it work when using Radeon HD6670 with open source video driver on Arch Linux?
Not sure if OpenCL is implemented in the free radeon driver.
I don't want to install catalyst.

Well, I did a quick Google search and found this:
https://wiki.archlinux.org/index.php/GPGPU

Looks like OpenCL is supposed to work with AMD graphics on Arch Linux, in theory, though only with the "catalyst" driver. But I guess you'll have to try and see...

Quote:
As AMD APP SDK itself contains CPU OpenCL driver, no extra driver is needed to use execute OpenCL on CPU devices (regardless of its vendor). GPU OpenCL drivers are provided by the catalyst package (an optional dependency), the open-source driver (xf86-video-ati) does not support OpenCL.

Open source OpenCL support is being added to Gallium3D. Your GPU happens to be in the generation that has received most of the attention, but support is still far from complete: http://dri.freedesktop.org/wiki/GalliumCompute/

For now, closed drivers are the only option for usable OpenCL support on Linux (or any OS).
