LuxMark is a [http://www.khronos.org/ OpenCL] benchmark tool. The idea for the program was conceived in 2009 by Jromang. It was intended as a promotional tool for [http://www.luxrender.net LuxRender] (to quote original Jromang's words: "LuxRender propaganda with OpenCL"). The idea was quite simple, wrap [[SLG]] inside an easy to use graphical user interface and use it as a benchmark for OpenCL. After [http://www.anandtech.com/show/4008/nvidias-geforce-gtx-580/16 Anandtech] adoption of [[SLG]] as OpenCL benchmark, the code was finally written.

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. It is intended as a promotional tool for [http://www.luxrender.net LuxRender] and it is now based on [[LuxCore]], the LuxRender v2.x C++ or Python API available under Apache Licence 2.0 and freely usable in open source and commercial applications.
  
After a year from LuxMark v1.0 release, it has been widely used as OpenCL benchmark by AnandTech, Tom's Hardware, Vr-zone and other sites.
+
== OpenCL render engine ==
AMD has used LuxMark as one of the 5 GPU computing benchmarks to present the new HD7970.
+
  
LuxMark v2.0 includes SLG2 as rendering engine with Metropolis Light Transport, Multiple Importance Sampling, Image reconstruction done on the GPU, support for multiple OpenCL platforms (i.e. Nvidia users can use Intel or AMD CPU device) and many more new features.
+
A brand new micro-kernel based OpenCL path tracer is used as rendering mode for the benchmark.
The new features rise the complexity of the benchmark of nearly one order of magnitude and it should be able to put some serious stress on the new generation of GPUs.
+
However, the capability to submit results to a centralise WEB database looks like the most interesting new feature of LuxMark v2.0: http://www.luxrender.net/luxmark
+
  
<div align="center">[[Image:LuxMark_20.jpg|640px]]</div>
+
== C++ render engine ==
  
== Features ==
+
This release includes the come back of a benchmarking mode not requiring OpenCL (i.e. a render engine written only in C++ like in LuxMark v1.x). Ray intersection C++ code uses state-of-the-art Intel [https://embree.github.io Embree].
  
* Open source
+
== Stress mode ==
* 100% OpenCL
+
* Cross platform (Linux, MacOS, Windows, etc.)
+
* Complex/real world code used as GPU computing benchmark
+
* Support for OpenCL GPUs-only, OpenCL CPUs+GPUs, OpenCL CPUs-only and native CPU-only benchmarking
+
* Support for Interactive mode
+
* Easy to run
+
* Multiple scenes usable as benchmarks
+
  
New in LuxMark v2.0:
+
Aside from benchmarking modes, it is also available a stress mode to check the reliability of the hardware under heavy load.
  
* Totally new rendering engine based on SLG2 with Metropolis Light Transport, Multiple Importance Sampling, Image reconstruction done on the GPU, ecc;
+
== Benchmark Result Validation ==
* Multi-platform OpenCL support;
+
* 2 new benchmark scenes, for a total of 3 benchmarks with a raising complexity (~200,000, ~500,000, ~2,000,000 triangles);
+
* Run the benchmark only on the OpenCL devices you selected on the device panel;
+
* Added the possibility to submit the scored result to a centralised result database: http://www.luxrender.net/luxmark;
+
  
== Download ==
+
LuxMark now includes a validation of the rendered image by using the same technology used for [http://pdiff.sourceforge.net pdiff] in order to check if the benchmarked result is valid or something has gone wrong. It has also a validation of the scene sources used (i.e. hash of scene files). While it will still possible to submit fake results to the LuxMark result database, it will make this task harder.

LuxMark v3.x

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. It is intended as a promotional tool for LuxRender and it is now based on LuxCore, the LuxRender v2.x C++ or Python API available under Apache Licence 2.0 and freely usable in open source and commercial applications.

OpenCL render engine

A brand new micro-kernel based OpenCL path tracer is used as rendering mode for the benchmark.

C++ render engine

This release includes the come back of a benchmarking mode not requiring OpenCL (i.e. a render engine written only in C++ like in LuxMark v1.x). Ray intersection C++ code uses state-of-the-art Intel Embree.

Stress mode

Aside from benchmarking modes, it is also available a stress mode to check the reliability of the hardware under heavy load.

Benchmark Result Validation

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. It has also a validation of the scene sources used (i.e. hash of scene files). While it will still possible to submit fake results to the LuxMark result database, it will make this task harder.

LuxVR

LuxVR is included as demo too and replaces the old "Interactive" LuxMark mode.

A brand new web site

There is now a brand new web site dedicated to LuxMark result: http://www.luxmark.info. It includes many new features compared the old results database.

Benchmark Scenes

3 brand new scenes are included. The simple benchmark is the usual "LuxBall HDR" (217K triangles):

The medium scene is the "Neumann TLM-102 Special Edition (with EA-4 shock mount)" (1769K traingles) designed by Vlad "SATtva" Miller (http://vladmiller.info/blog/index.php?comment=308):

The complex scene is the "Hotel Lobby" (4973K) designed by Peter "Piita" Sandbacka:

Command line options

Usage: luxmark [options]

--help (display this help and exit)
--scene=LUXBALL_HDR|MICROPHONE|HOTEL (select the scene to use)
--mode=BENCHMARK_OCL_GPU|BENCHMARK_OCL_CPUGPU|BENCHMARK_OCL_CPU|BENCHMARK_NATIVE|STRESSTEST_OCL_GPU|STRESSTEST_OCL_CPUGPU|STRESSTEST_OCL_CPU|DEMO_LUXVR|PAUSE (select the mode to use)
--single-run (run the benchmark, print the result to the stdout and exit)
--ext-info (print scene and image verification too with --single-run)

What is new in v3.1 ?

- The new LuxRender v1.5 render engine. Among other features, it includes some OpenCL optimization suggested by NVIDIA to LuxRender project. Because of the general score improvements in v3.1, it is not fair to compare LuxMark v3.0 results with LuxMark v3.1;

- OpenCL "overclocking" (OpenCL C compiler options: -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. By default, the following options are enabled: "-cl-fast-relaxed-math -cl-mad-enable -cl-no-signed-zeros". "-cl-strict-aliasing" is not enabled by default because Intel compiler is broken and it doesn't support this standard option.

- a new command line --ext-info option (http://www.luxrender.net/forum/viewtopic.php?f=8&t=12278#p115645);

- a fix for OpenCL device with weird names (http://www.luxrender.net/forum/viewtopic.php?f=34&t=11585&start=50#p115646);
