And my OS is centos 6.7.</P> <P>I'm building x264-snapshot-20160807-2245-stable, and want to use opencl acceleration function. But x264 will report 'failed to load OpenCL', when opencl is on and x264 is run.</P> <P>How to install opencl on centos 6.7 to support intel integrated GPUs for 'Intel(R) Xeon(R) CPU E5-2640 v3' and make x264 run with opencl option?</P> <P>Thanks</P> <P>Andrew</P> <P>&nbsp;</P> Fri, 12 Aug 2016 03:56:06 GMT https://community.intel.com/t5/OpenCL-for-CPU/How-to-install-opencl-for-Intel-R-Xeon-R-CPU-E5-2640-v3/m-p/1094257#M4987 applemax82 2016-08-12T03:56:06Z https://community.intel.com/t5/OpenCL-for-CPU/How-to-install-opencl-for-Intel-R-Xeon-R-CPU-E5-2640-v3/m-p/1094258#M4988 <P>Sorry for the delayed reply.&nbsp; The Xeon E5 line does not have processor graphics, so the GPU on that system would not be from Intel.&nbsp; You could install an Intel&nbsp;CPU runtime, but x264 is very well optimized for CPU already so that is not likely to provide any performance benefit.&nbsp;</P> Sat, 10 Sep 2016 02:04:30 GMT https://community.intel.com/t5/OpenCL-for-CPU/How-to-install-opencl-for-Intel-R-Xeon-R-CPU-E5-2640-v3/m-p/1094258#M4988 Jeffrey_M_Intel1 2016-09-10T02:04:30Z
