Detailed Description

Singleton accessor for a process-wide HighPerformancePool instance.

Provides static convenience methods that forward to a single HighPerformancePool whose lifetime is managed as a function-local static (Meyer's singleton).

Thread safety

The underlying pool is created on the first call to instance() and is guaranteed to be thread-safe in C++11 and later (magic statics). All forwarded methods (submit, submit_batch, parallel_for_each) are as thread-safe as the corresponding HighPerformancePool methods.

Pool size

The pool is created with std::thread::hardware_concurrency() threads. This size is fixed for the lifetime of the process; there is no API to resize the singleton pool after creation.

Static destruction order

Because the pool is a function-local static, it is destroyed during static destruction in reverse order of construction. Submitting work to the global pool from destructors of other static objects is undefined behaviour if the pool has already been destroyed. Prefer explicit lifetime management in programs with complex static initialization dependencies.

Copyability / movability

Not instantiable (private constructor). All access is through static methods.
