Taskflow is a header-only C++ library for building task-parallel programs using task dependency graphs, with a work-stealing executor for CPUs and GPUs (CUDA). It includes a web-based profiler (TFProf) for visualizing and profiling taskflow executions.

Use cases

• parallelize a C++ application across CPU cores with a task graph
• express task dependencies like fork-join and pipeline patterns
• run recursive parallel algorithms with subflow graphs
• accelerate workloads on NVIDIA GPUs with CUDA tasking
• profile and visualize parallel task execution
• scale machine learning or simulation workloads to millions of tasks

When to choose

• you need high-performance task parallelism in modern C++ with minimal setup
• you want a header-only library with no installation burden
• you need both CPU and GPU (CUDA) heterogeneous parallelism
• you want built-in profiling and visualization of task graphs

When to avoid

• you need distributed multi-node parallelism rather than a single machine
• your project is not C++ or targets an older C++ standard
• you only need simple thread pools without task dependency graphs
