![]() ![]() a fix for OpenCL device with weird names ( ) a new command line -ext-info option ( ) "-cl-strict-aliasing" is not enabled by default because Intel compiler is broken and it doesn't support this standard option. By default, the following options are enabled: "-cl-fast-relaxed-math -cl-mad-enable -cl-no-signed-zeros". ![]() a new "OpenCL Compiler Options" menu in order to allow the user to enable/disable single compiler options. OpenCL "overclocking" (OpenCL C compiler options: -cl-fast-relaxed-math -cl-mad-enable -cl-no-signed-zeros) Because of the general score improvements in v3.1, it is not fair to compare LuxMark v3.0 results with LuxMark v3.1 Among other features, it includes some OpenCL optimization suggested by NVIDIA to LuxRender project. ext-info (print scene and image verification too with -single-run) single-run (run the benchmark, print the result to the stdout and exit) STRESSTEST_OCL_CPUGPU|STRESSTEST_OCL_CPU|DEMO_LUXVR|PAUSE (select the mode to use) mode=BENCHMARK_OCL_GPU|BENCHMARK_OCL_CPUGPU|BENCHMARK_OCL_CPU|BENCHMARK_NATIVE|STRESSTEST_OCL_GPU| scene=LUXBALL_HDR|MICROPHONE|HOTEL (select the scene to use) The simple benchmark is the usual "LuxBall HDR" (217K triangles):Ĭommand line options Usage: luxmark It includes many new features compared the old results database.ģ brand new scenes are included. There is now a brand new web site dedicated to LuxMark result. LuxVR is included as demo too and replaces the old "Interactive" LuxMark mode. While it will still possible to submit fake results to the LuxMark result database, it will make this task harder. It has also a validation of the scene sources used (i.e. LuxMark now includes a validation of the rendered image by using the same technology used for pdiff in order to check if the benchmarked result is valid or something has gone wrong. Ray intersection C++ code uses state-of-the-art Intel Embree.Īside from benchmarking modes, it is also available a stress mode to check the reliability of the hardware under heavy load. a render engine written only in C++ like in LuxMark v1.x). This release includes the come back of a benchmarking mode not requiring OpenCL (i.e. It is intended as a promotional tool for LuxCoreRender and it is now based on LuxCore API, the LuxCoreRender v2.x C++ or Python API available under Apache Licence v2.0 and freely usable in open source and commercial applications.Ī brand new micro-kernel based OpenCL path tracer is used as rendering mode for the benchmark. Let’s test it in the next step.LuxMark is a OpenCL cross-platform benchmark tool and has become, over past years, one of the most used (if not the most used) OpenCL benchmark. Once complete, you should see a series of outputs that end in done.:Ĭongratulations! You should have a working installation of CUDA by now. Sudo mv cuda-wsl-ubuntu.pin /etc/apt/preferences.d/cuda-repository-pin-600 Then setup the appropriate package for Ubuntu WSL: Also notice that attempting to install the CUDA toolkit packages straight from the Ubuntu repository (“cuda”, “cuda-11-0”, or “cuda-drivers”) will attempt to install the Linux NVIDIA graphics driver, which is not what you want on WSL 2. Be aware that older versions of CUDA (<=10) don’t support WSL 2. The following commands will install the WSL-specific CUDA toolkit version 11.6 on Ubuntu 22.04 AMD64 architecture. ![]() On WSL 2, the CUDA driver used is part of the Windows driver installed on the system, and, therefore, care must be taken not to install this Linux driver as previously mentioned. Normally, CUDA toolkit for Linux will have the device driver for the GPU packaged with it. ![]()
