Taskflow 3.4.0 is the newest developing line to new features and improvements we continue to support. It is also where this documentation is generated. Many things are considered experimental and may change or break from time to time. While it may be difficult to be keep all things consistent when introducing new features, we continue to try our best to ensure backward compatibility.

Download

To download the newest version of Taskflow, please clone the master branch from Taskflow's GitHub.

System Requirements

To use Taskflow v3.4.0, you need a compiler that supports C++17:

• GNU C++ Compiler at least v8.4 with -std=c++17
• Clang C++ Compiler at least v6.0 with -std=c++17
• Microsoft Visual Studio at least v19.27 with /std:c++17
• AppleClang Xode Version at least v12.0 with -std=c++17

Release Summary

New Features

Taskflow Core

• Improved the pipeline performance using vertical stack optimization
• Added tf::ScalablePipeline to allow programming variable lengths of pipes
• Added an example of attaching data to a task (examples/attach_data.cpp)
• Added an example of text processing pipeline (examples/parallel_text_pipeline.cpp)
• Added an example of graph processing pipeline (examples/parallel_graph_pipeline.cpp)
• Added an example of taskflow processing pipeline (examples/parallel_taskflow_pipeline.cpp)

cudaFlow

• Added tf::cudaStream as a move-only, RAII-styled wrapper over a native CUDA stream
• Added tf::cudaEvent as a move-only, RAII-styled wrapper over a native CUDA event

syclFlow

Utilities

• removed serializer to improve compilation speed

Taskflow Profiler (TFProf)

• Disabled local TFProf support due to non-portable serialization

Bug Fixes
