concurrency

This library provides high-level abstractions for implementing algorithms that ease using multiple CPU cores while minimizing contention.

The stlab::future implementation differs in several aspects from the C++11/14/17 std::future:

• Provides continuations (then) and joins (when_all and when_any).
• Support splitting by attaching multiple continuations to a single future.
• Automatically cancel any uniquely contributing tasks when a future is destroyed.
• Supports custom executors.
• Auto-reduces, i.e., a future<future<T>> is automatically converted to a future<T>.

The library provides a default executor that uses the system thread pool, if available. Otherwise, it uses a portable, high-performance, elastic, task-stealing executor. The library also provides a number of utilities and experimental features.

Requirements

• C++17 compliant compiler (clang, gcc, Visual Studio)
• boost (for executing the unit tests)
