why is boinc missing opengl?

OpenCL ... unless you're not confusing it with OpenGL

--//--

The driver version is unknown, so BOINC cannot determine whether or not your GPU is OpenCL (or indeed OpenGL) capable. It will try to do that by reading a specific file that's included with the drivers.

Download and install the drivers from Nvidia to have these capabilities included. Don't use the 295.xx-296.xx drivers as these contain a monitor sleeping bug that crashes work on the various projects.

Oh wait a moment, I don't even think that Nvidia has OpenCL drivers yet. And even if they do, it will probably be for Windows only at this time.

And even if you had it to work at one time, it's the driver that's missing the part. There's nothing magical about BOINC supporting OpenCL, it reads the GPU capabilities from a file in your drivers. If this file is missing, BOINC can't read what's going on and will throw an error. So double check the driver, double check that you installed it under the same account that BOINC runs from.

Windows drivers since 197.xx have supported OpenCL, i have been running Raistmer's Nvidia OpenCL AP app for the last year, and Seti Beta now has the latest Nvidia AP app as a Stock app (all on Windows)

you can see here that there is OpenCl suport times ago...

since Oktober 2009!

also there is /usr/lib/OpenCL/vendors/nvidia/libOpenCL.so.1.0.0

Any of Nvidia's GPUs that's capable of CUDA can do OpenCL. I know that. But it doesn't automatically mean that there are drivers available for the OS. See Macintosh computers and AMD GPUs. They're supposed to be supported through drivers in the Mac OS X, but it doesn't work.

also there is /usr/lib/OpenCL/vendors/nvidia/libOpenCL.so.1.0.0

And where is your BOINC installed to? I see your data directory is at /home/stephan/Downloads/BOINC/, so if BOINC is also installed in /home/stephan/ then it's physically separated from the drivers (sandboxing), which is why BOINC won't be able to read them.

I checked the source code and see that BOINC checks for OpenCL.dll under Windows and opencl_lib under *nix and Mac OS X.

Are you also using the i5-2500K's Intel HD Graphics 3000 GPU for display?

Earlier versions of Boinc 6.12.x (on Windows) had a problem with Dual Nvidia/Intel Laptops where Boinc couldn't get the driver version,

It was fixed (at least on windows systems) by Jason G and Richard Haselgrove with this changeset: [trac]changeset:24046[/trac]

i have installed it by the boinc_7.0.27_x86_64-pc-linuc-gnu.sh direkt in the "download" because i`m using gentoo which depends on compiling by wrong glibc -version (ver 2.1.5 is needed)

will try installing if glibc comes up and look

no, the IGP is deactivatet

also there is /usr/lib/OpenCL/vendors/nvidia/libOpenCL.so.1.0.0

The Linux client checks for libOpenCL.so (without version number), you could try adding a symbolic link.

Fedora and Ubuntu are most likely using Journaled file systems (ext3, ext4). This means that each version of the file saved to the file system gets a version number appended to the end of the file name.

I know that this is true for both of the Linux Distros tht I am using (both Fedora and Ubuntu)

However, this is not the sole issue.

I have the recommended Files block in xorg.conf, and i set a link in the file system to show libOpenCL.so as a linked file, but Boinc still does NOT recognize that the driver supports OpenGL/CL for this GTX660 Ti

I repeat myself for emphasis, BOINC does NOT recognize that OpenGL/CL is a supported protocol for Nvidia 304.64 driver on Fedora 18 Nvidia has examined all my related files and says that the installation of the driver and configuration of xorg.conf are CORRECT!

And last but not least, BAM! account manager does not recognize the strings of data sent by BOINC 7.0.29 on Fedora 18. The problem appears to be related to the OpenGL/CL issue.

CUDA apps are running happily in this environment, some BOINC apps will NOT run as they insist on OpenCL/GL support

Please post your Boinc startup messages from the Event Log, the first 20 to 30 lines will do.
