So they're working on a patch, should be finished by next week. I'm curious if it will work with e@h.

Could a forum moderator move beignet related postings to a separate thread?
Thank you.

I've installed a recent kernel and it seems to work one step further, but I get an other error message.
Seems to be a bug in beignet.

(Link?)

Permissions are ok.

I just found this in the beignet documentation:
"Some unit test cases, maybe 20 to 30, fail on 4th Generation (HSW) platform. The 4th Generation Intel Core Processors's support requires some Linux kernel modification."
I don't know if that's what's missing.

And then there's:
"Almost all unit tests fail on Linux kernel 3.15/3.16"
uname: Debian 3.16.7-ckt7-1 (2015-03-01) x86_64 GNU/Linux

The driver itself seems to be fine:

So maybe I need to try a newer kernel?

Let's assume it's tomorrow already.

Ah I see, debian testing provides an old version of beignet that doesn't support Haswell. I'll test a recent version tomorrow.

Thank you.

I tried and I failed.
Can someone provide me a app_info.xml for this?

I've installed beignet and it is even detected by boinc!
OpenCL: Intel GPU 0: Intel(R) HD Graphics Haswell M (driver version 0.8.0, device version OpenCL 1.1 beignet 0.8.0, 128MB, 128MB available, 512 GFLOPS peak)

Now how do I get einstein running on this? :)

Ok with the wisdomf it's running a lot faster, around 63500s each.
