Config Struct Reference

#include "vault/gear/work-force.hpp"

Description

Base for configuration of the worker pool.

In real usage, a subclass of #Config is used, which additionally defines the two required functors

• doWork : perform a piece of work and return control code
• finalHook : callback invoked at work thread termination Obviously these two functors are defined in a way to call into the actual implementation of work management (i.e. the Scheduler).

COMPUTATION_CAPACITY

size_t COMPUTATION_CAPACITY = Config::getDefaultComputationCapacity()

static

Nominal »full size« of a pool of concurrent workers.

This value is initialised to use all available concurrent computing cores, but can be adjusted. Adjustments should be done before a worker pool scales up.

Warning

this value is taken as-is; setting it to zero will disable many (but not all) aspects of concurrent processing.
