Hey Everyone, Finally got OpenCL working again on v4.4.x, lots of fun "dkms" module issues, so ripped all those out..
mkbian@beaglebone:/usr/share/ti/examples/opencl/float_compute$ sudo modprobe cmem This example computes y[i] = M[i] * x[i] + C on single precision floating point arrays of size 2097152 - Computation on the ARM is parallelized across the A15s using OpenMP. - Computation on the DSP is performed by dispatching an OpenCL NDRange kernel across the compute units (C66x cores) in the compute device. Running..... Average across 5 runs: ARM (2 OpenMP threads) : 0.008669 secs DSP (OpenCL NDRange kernel) : 0.007781 secs OpenCL-DSP speedup : 1.114124 For more information on: This Sunday's lxqt image will have all the fun bits.. For older images do this: sudo apt-get update sudo apt-get upgrade sudo apt-get remove dkms --purge #get rid of dkms/etc.. cd /opt/scripts/tools/ git pull sudo ./update_kernel.sh sudo reboot cd /usr/share/ti/examples/opencl/float_compute/ sudo make sudo modprobe cmemk sudo ./float_compute Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
