+ ** 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.
