stdexec is NVIDIA's reference implementation of std::execution, the C++26 standard framework for asynchronous and parallel programming based on the sender/receiver model (P2300). It lets developers compose lazy asynchronous pipelines that run on threads, thread pools, GPUs, or custom schedulers with structured concurrency guarantees.

Use cases

• compose asynchronous work as lazy sender pipelines in C++
• run parallel computations on a thread pool with structured concurrency
• schedule GPU work from C++ with a standard async model
• replace callbacks and std::async with composable async algorithms
• integrate coroutines with asynchronous execution via co_await on senders
• prototype C++26 std::execution APIs before compilers ship them

When to choose

• you want a modern, composable, zero-overhead async model in C++20+
• you need structured cancellation and error handling for concurrent tasks
• you are targeting heterogeneous execution across CPUs and GPUs
• you want to future-proof code against the C++26 execution standard

When to avoid

• you need a stable, frozen API for production-critical code
• your compiler cannot handle heavy C++20 template metaprogramming
• you only need simple threading with std::thread or std::async
• you require a small dependency footprint in legacy C++ codebases
