Hi all,
Thank you for pay close attention to our latest release. We are very sorry
that we are not very thoughtful about the package making things.
We did not have a performance test for OCL2.0 so we did not set it as a default
option and we did not think about how to run a binary version on
As for the "OpenCL 2.0 = worse performance" problem, the OpenCL spec
actually _requires_ 2.0 compilers to default to 1.2, and only enable
2.0 if explicitly asked to:

It worked for me, and here it is; testing on other hardware (in
particular, hardware that supports 2.0: the last 15 tests of the test
suite appear to be the ones that test that) would be
I have a first attempt at "enable/disable 2.0 at run time" written, but
haven't yet tested it.

Hi there,
First post here, so first of all thanks for building Beignet and this
1.3 release!
I’m ArchLinux packager for beignet[0], and I’m trying to figure out
