    The beignet devs haven't really put any time into performance work as of yet, they've been working on ocl-1.1/1.2 coverage. However, quite likely the problem here is due to gpu lock-ups (which I get...
  2. Gentoo Overlay

    I'm still maintaining a gentoo overlay with modified mesa ebuilds integrating beignet:

  3. Gentoo DOES support systemd

    What's with all the claims that Gentoo doesn't support systemd? OpenRC is the default, but the entire point of Gentoo is you chose which USEflags *you* want. I've been using systemd on Gentoo for...

    llvm/clang auto-vectorizes by default, right? I thought gcc did too on relevant targets at -O3, via "-ftree-vectorize", but according to "gcc -O3 -march=native -Q --help=optimizers" it doesn't!

  6. Journalism vs Reporting

    Do people really not understand the difference between journalism and reporting? Have people been so conditioned to only accept "official" press releases as "news", and should be reported as is;...

    "-Ofast" will almost certainly give you faster binaries. You just need to be sure your code is "fast-math" safe.

    Multilib/Multiarch works fine on Linux, and has done at least since the beginning of the amd64 port. The only real issues have been lack of a standardized approach as to where to keep the...

    Thank you for this comment. Right now from studying the code and reading about the implementation, the gallium-nine wine patch falls back to the wine d3d->opengl pipeline in cases it can't handle,...

    Nouveau is Gallium3D. I'm working on getting it going on Intel too, utilising the ilo Gallium3D driver. (Yes, this should work even while using the Classic i965 DRI driver since gallium-nine uses...

    You mean "poorly reinvented VMS" from http://en.wikipedia.org/wiki/Windows_NT :

    Yes and no. Lots of 1U rackmount chassis do actually support 5.25" bays, however WD actually also have models of VelociRaptor without the sink, particularly for deployment in *well ventilated* 2.5"...

    That's probably because the btrfs default mount options are quite conservative: space_cache and inode_cache (once it's completed creating the cache*) should give noticeably better performance, as...

    The current Fedora 20 graphics stack is far from ideal; he really should upgrade to llvm-3.4 and Mesa-10, or even better git snapshots of both. I don't know what Red Hat was thinking, really,...

    It's not really fair to compare performance of a 1TB drive to a 150GB drive. The storage density is *much* higher on the 1TB so much more data passes under the read heads each rotation, and the head...

    Gallium3d has an OpenVG state tracker, and it's supported by pretty much all of the hw drivers AFAIK. Even ilo (i965) has it available:
