After some further investigation. The APP1 and APP3 (dnetc and wwwwcl) issues should be caused by the same bug and we are working on fixing it.
But the APP2(tpsieve) may not be beignet issue. I quickly tested it with POCL, and it also triggers many errors which are very similar with beignet's. Did you try it with any other OpenCL runtime library? > -----Original Message----- > From: Beignet [mailto:beignet-boun...@lists.freedesktop.org] On Behalf Of > Zhigang Gong > Sent: Saturday, November 29, 2014 1:54 PM > To: Roman Trunov > Cc: beignet@lists.freedesktop.org > Subject: Re: [Beignet] Still cannot use beignet with real OpenCL applications > (Haswell CPU) > > Forgot to cc the list. > > On Sat, Nov 29, 2014 at 12:10 PM, Zhigang Gong <zhigang.g...@gmail.com> > wrote: > > Thanks for reporting issues.
