PROBLEM: Applications compiled against one implementation of OpenCL (libOpenCL.so) will not run on a system with another implementation installed. OpenCL loader library is supposed to be agnostic to the kernel loaded (nvidia libOpenCL.so will run amd kernels for example) but testing has shown significant performance differences when using OpenCL implementations from different vendors. System must have libOpenCL.so used at build time in order to run an application using OpenCL As the number of OpenCL applications grows there will be packaging conflicts between those built against nvidia/ocl and potentially other vendor OpenCL implementations as they are added to ubuntu. Solution: ocl-icd-libopencl1 (http://packages.ubuntu.com/trusty/ocl-icd- libopencl1) provides an open source implementation of libOpenCL.so that will work with vendor OpenCL kernels files provided by intel/nvidia/amd. Policy for packages to use ocl-icd as the default implementation, allowing the use of other kernel loaders for alternative packages in the same source package(if desired) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-driver/+bug/1328542/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
