Mandelbrot set

Draw the Mandelbrot set using single thread CPU, multi-thread CPU, and GPU.

Requirements

• OpenCV 4.3.0
• Threading Building Blocks (TBB) v2020.2 [for multi-thread]
• CUDA Toolkit 11.0 [for GPU]

Windows

• Visual Studio 2019

Linux

• GCC 8.3
• pkg-config 0.29

Build

Single-thread

• Windows (MS VS2019)

> cl /EHsc /W3 /nologo /O2 /Zi /MT mandelbrot_single.cpp opencv_world430.lib

• Linux (GCC 8.3)

$ g++ mandelbrot_single.cpp `pkg-config --libs opencv` `pkg-config --cflags opencv` -std=c++11 -O3 -o mandelbrot_single

Multi-thread using TBB

• Windows (MS VS2019)

> cl /EHsc /W3 /nologo /O2 /Zi /MT mandelbrot_multi.cpp tbb.lib opencv_world430.lib

• Linux (GCC 8.3)

$ g++ mandelbrot_multi.cpp `pkg-config --libs opencv` `pkg-config --cflags opencv` -std=c++11 -ltbb -O3 -o mandelbrot_multi

GPU using CUDA

• Windows (MS VS2019)

> nvcc -Xcompiler /EHsc,/W3,/nologo,/O2,/Zi,/MT mandelbrot_gpu.cu opencv_world430.lib -o mandelbrot_gpu

• Linux (GCC 8.3)

$ nvcc `pkg-config --libs opencv` `pkg-config --cflags opencv` mandelbrot_gpu.cu -o mandelbrot_gpu

Benchmarks
