Guest tar Posted February 21, 2015 Share Posted February 21, 2015 (edited) Is anyone successfully running OpenCL with a Gtx 980 in Linux/ubuntu? So far the driver 343.22 says no OpenCL devices. Just posting this here till I can update the drivers. Edit: 346.35 drivers show 'No Configured OpenCL Device' Must be something basic with Nvidia that is missing. AMD OpenCL on Linux installs with the graphics driver. Edit2: OpenCL CPU is working fine. Edit3: This appears common, missing OpenCL with 970//980 depending on installation method of drivers. Happy happy joy joy! https://foldingforum.org/viewtopic.php?p=270804 Thanks! Edited February 21, 2015 by tar Quote Link to comment Share on other sites More sharing options...
matsbt Posted February 21, 2015 Share Posted February 21, 2015 (edited) I'm not running Ubuntu or nVidia R346.35, but I had to add a line to /etc/rc.d/rc.local under Slackware running nVidia R340.76 to keep the CUDA/OpenCL device after a reboot: # Create missing nvidia device nodes after reboot /usr/bin/nvidia-modprobe -c 0 -u Make sure you have nvidia-modprobe installed. Also, make sure you have the nvidia-uvm kernel module installed as well: crw-rw-rw- 1 root root 248, 0 feb 21 10:47 /dev/nvidia-uvm crw-rw-rw- 1 root root 195, 0 feb 21 10:52 /dev/nvidia0 crw-rw-rw- 1 root root 195, 255 feb 21 10:52 /dev/nvidiactl I only have a GeForce 9300M GS but it's detected as an OpenCL device in Houdini 13/14: OpenCL Platform NVIDIA CUDAPlatform Vendor NVIDIA CorporationPlatform Version OpenCL 1.1 CUDA 6.5.45OpenCL Device GeForce 9300M GSOpenCL Type GPUDevice Version OpenCL 1.0 CUDA Edited February 21, 2015 by matsbt Quote Link to comment Share on other sites More sharing options...
