graph/binpack	A solution to the binpacking problem using a queue_node, a buffer_node, and function_nodes.
graph/cholesky	Several versions of Cholesky Factorization algorithm implementation.
graph/dining_philosophers	An implementation of dining philosophers in a graph using the reserving join_node.
graph/fgbzip2	A parallel implementation of bzip2 block-sorting file compressor.
graph/logic_sim	An example of a collection of digital logic gates that can be easily composed into larger circuits.

parallel_pipeline/square	Another string transformation example that squares numbers read from a file.
parallel_reduce/convex_hull	Parallel version of convex hull algorithm (quick hull).
parallel_reduce/pi	Parallel version of calculating π by numerical integration.
parallel_reduce/primes	Parallel version of the Sieve of Eratosthenes.
task_arena/fractal	The example calculates two classical Mandelbrot fractals with different concurrency limits.
task_group/sudoku	Compute all solutions for a Sudoku board.
test_all/fibonacci	Compute Fibonacci numbers in different ways.

System Requirements

Refer to the System Requirements for the list of supported hardware and software.

Graphical User Interface (GUI)

Some examples (e.g., fractal, seismic, tachyon, polygon_overlay) support different GUI modes, which may be defined via the EXAMPLES_UI_MODE CMake variable. Supported values are:

• Cross-platform:
  • con - Console mode (Default).
• Windows* OS:
  • gdi - GDI+ based implementation.
  • d2d - Direct 2D based implementation. May offer superior performance but can only be used if the Microsoft* DirectX* SDK is installed on your system(DXSDK_DIR should be defined).
• Linux* OS:
  • x - X11 based implementation. Also libXext may be required to display the output correctly.
• macOS*:
  • mac - OpenGL based implementation. Also requires the Foundation and Cocoa libraries availability.
