Brian OK. I suspected that I wouldn't find an off-the-shelf solution. If I ignore cuda and just want hardware accelerated GL, can I find what I need on the wiki? I didn't manage to locate the info yet (any hints to links appreciated). This morning some NVidia people were in the building and I asked them about a cuda+GL solution for HPC machines and they have offered their assistance, so I'll report back if any solution is out there.

Cc: [email protected] Subject: Re: [Mesa-users] Status of MesaGL on headless GPU machines I think your best shot at Cuda-OpenGL integration will be with NVIDIA's own Cuda/OpenGL drivers. I don't follow Mesa's support for NVIDIA GPUs too closely, but I doubt anyone's really addressed Cuda interoperability. -Brian On 02/22/2013 12:13 AM, Biddiscombe, John A. wrote: > I have not been following progress of developments closely and am > still using mesa 7.6.1 on most of my CPU only machines (because it > works reliably for the plain OpenGL stuff). > > I'd like to run some Cuda-OpenGL interop tests on one of our GPU > enabled machines with Tesla K20X GPUs installed (272 of them). > > Is there any version of mesa that I can use on these type of systems > that allows me to > > a)Make use of the hardware > > b)Pass arrays from cuda to mesa GL for VBOs etc to avoid CPU/GPU > exchange of arrays at each render. > > In the past the lack of any X installation was a problem with hardware > access, but with mesa 9.x perhaps this has changed and it's now > possible for me to use an accelerated GL on these machines. > > I'd welcome any info - I looked through the nouveau wiki but didn't > see anything that was encouraging, so I'm guessing I can't use the > GPUs for graphics. > > Thanks. > > JB > > -- > > John Biddiscombe, email:biddisco @.at.@ cscs.ch > > http://www.cscs.ch/ > > CSCS, Swiss National Supercomputing Centre | Tel: +41 (91) 610.82.07 > > Via Trevano 131, 6900 Lugano, Switzerland | Fax: +41 (91) 610.82.82 > > > > _______________________________________________ > mesa-users mailing list > [email protected] > http://lists.freedesktop.org/mailman/listinfo/mesa-users
