Smallpt

Smallpt is a C++ global illumination renderer written in less than 100 lines of code. Global illumination is done via unbiased Monte Carlo path tracing and there is multi-threading support via the OpenMP library.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark smallpt.

Performance Metrics

Analyze Test Configuration:

Smallpt 1.0

Global Illumination Renderer; 128 Samples

OpenBenchmarking.org metrics for this test profile configuration based on 3,301 public results since 7 December 2018 with the latest data as of 23 January 2021.

Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.
