![]() I've been trying for hours to install the Intel Media Server Studio 2015 R6 – Community Edition for Linux so that I can use the GPU on my Xeon E3-1246v3, but no matter what I try I can't seem to get it to work. If it isn't bug in my system - maybe it will be better for Intel® to support pocl (which still has a lot of problem with standards support and stability) in stead of development own driver? Looks strange - open source library pocl ( ) beats official Intel® software in such simple test case (don't look at "Clock Frequency" reported - when loaded it runs at 2300 MHz in both cases). Name: pthread-Intel(R) Core(TM) i5-4200U CPU 1.60GHz Name: Intel(R) HD Graphics Haswell Ultrabook GT2 Mobile Used Intel® software was OpenCL CPU driver opencl_runtime_15.1_圆4_5.0.0.57 from Ĭompare Beignet (GPU, id 0) vs Intel® proprietary driver (CPU, id 1) vs pocl (CPU, id perftest.c -std=c11 -O2 -lOpenCL -o for id in 0 1 2 do time. Can anyone confirm that, or point me to another possible cause? Thanks in advance! ![]() My suspicion is that there is something not right with the driver. Using the INDE IDE it produces the error message above. INDE 2015 update 2 does not compile an OpenCL kernel on Win10: it doesn't produce any output using the command line compiler.Trying to install the newest OpenCL driver for the HD 4600 on Win10 just reinstalls the current driver.OpenCL code that runs fine on Win7, does not run on the same hardware on Win10: clSetKernelArg returns CL_INVALID_ARG_SIZE.Using the INDE OpenCL code builder, building the OpenCL kernel produces error message IOC engine exited with code -1073740791. The command line OpenCL compiler, ioc64, is not working however. The installer complains that the OpenCL driver is missing or out of date, but gives the option to install INDE anyway, which I did. The installation seems to succeed, but installs version 10. I tried to upgrade to the newest driver version (15.40.). After upgrading to Windows 10 64bit, the call to clSetKernelArg fails and returns CL_INVALID_ARG_SIZE. On this PC with Windows 7 64bit, my OpenCL program runs correctly. I have a HP Z230 PC with an integrated Intel HD 4600 GPU.
