Interesting... After installation of the OpenCL drivers what is stored in the following registry key? HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors
That is where Nvidia and AMD currently register their user-mode components of the OpenCL framework. For AMD: amdocl.dll amdocl64.dll Nvidia: nvcuda.dll ----- Rom -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of zombie67 Sent: Saturday, September 01, 2012 6:44 PM To: [email protected] Subject: Re: [boinc_dev] openCL (not used) issue Yes, I also tried to install the Intel OpenCL driver, with the same problem. Slicker was working on an working on an app for collatz that would run on the integrated FPU in the intel sandybridge CPU. In any case, after installation of the driver, BOINC would not use my discrete GPU. Only uninstalling the driver worked. Note, the discrete GPU still worked. Just BOINC wouldn't use it.

Any OpenCL project I get "GPU missing, Ready to start" while any CAL or CUDA app runs fine. This is on BOINC 7.0.33 on the windows 8 x64 RTM enterprise 90 day trial. If I uninstall the Intel driver and restart, all is fine. > > Also, how is adding support for running openCL apps on the Intel chips coming along? > > ~Tank_Master > > _______________________________________________ > boinc_dev mailing list > [email protected] > http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev > To unsubscribe, visit the above URL and (near bottom of page) enter > your email address. _______________________________________________ boinc_dev mailing list [email protected] http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev To unsubscribe, visit the above URL and (near bottom of page) enter your email address. _______________________________________________ boinc_dev mailing list [email protected] http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev To unsubscribe, visit the above URL and (near bottom of page) enter your email address.
