/** @file test-chain-load.hpp
** Generate synthetic computation load for Scheduler performance tests.
** The [Scheduler](\ref scheduler.hpp) is a service to invoke Render Job instances
** concurrently in accordance to a time plan. To investigate the runtime and performance
** characteristics of the implementation, a well-defined artificial computation load is
** necessary, comprised of the invocation of an extended number of Jobs, each configured
** to carry out a reproducible computation. Data dependencies between jobs can be established
** to verify handling of dependent jobs and job completion messages within the scheduler.
