Hmm, don't remember. What was the OpenCL related problem for you in the end?

You for sure could benefit from migrating to 64-bit.

Ok, thanks.
If I want to try, where exactly I have to insert the option
"opencl_use_cpu TRUE"?

nice, thanks for that :) curious to see when if at all the cpu opencl code

Hi,
I just added a config option opencl_use_cpu_devices to git master.
Defaults to FALSE but can be set to TRUE if you want to give
OpenCL-on-CPU a try.
Here on my rig (Intel i7-2600 CPU @ 3.40GHz, AMD OpenCL driver) revealed
the following benchmark with a moderately complex history stack:

our cpu code path makes heavy use of manually optimized sse intrinsics, so
to support avx you need to rewrite that code in 8-wide (half of it should
be trivial, some other things not so much). or use intel's opencl for cpu
devices. those might be disabled in our code because in the past it didn't

Looking at the new Intel Haswell processors, it seems that it's new AVX2
extension can be particularly helpful for graphics processing. For example:

One option is to run gentoo and compile everything with the extensions
