Optimized PCL Troubleshooting

If the executable gives a segmentation fault (the core is dumped), the Docker* image was not opened with the
root
user.
If you can see the GPU in
sycl
, the user has the correct permissions:
sycl-ls [opencl:0] ACC : Intel(R) FPGA Emulation Platform for OpenCL(TM) 1.2 [2021.13.11.0.23_160000] [opencl:0] CPU : Intel(R) OpenCL 3.0 [2021.13.11.0.23_160000] [opencl:0] GPU : Intel(R) OpenCL HD Graphics 3.0 [22.17.23034] [level_zero:0] GPU : Intel(R) Level-Zero 1.3 [1.3.23034] [host:0] HOST: SYCL host platform 1.2 [1.2]
If the user does not have the correct permissions, add the user to the render group:
#replace userName with the actual user of your system sudo usermod -a -G render <userName>
