## Detailed Description

    Reference optionfile which shows in a simple way how to take advantage of the
    Gaudi components desicated to concurrency.
    The components are:
     o HiveWhiteBoard: a convenient way to collect several TES (one per "processing
     slot"), accessible in a thread safe way, keeps a catalogue of the products
     written on each processing slot. The number of slots in the whiteboard
     determines also the number of events processed simultaneously by the scheduler.
     o AvalancheSchedulerSvc: state machine of the algorithms interfaced with the
     TBB runtime. It is responsible for the submission of the algorithms. An
     algorithm is marked ready for submission when its needed input is available.
     It deals the asynchronous termination of algorithms with a "receiver" thread
     and a thread safe queue.
     o HiveSlimEventLoopMgr: an event factory. Pushes new events and pops finished
     events to/from the scheduler. It does not manage algorithms/streams.
     o AlgResourcePool: Service managing the creation of algorithms (through the
     algorithm manager), including clones. It also manages the algorithms according
     to the resources they need (parameter NeededResources - vector of strings - of
     the Algorithm class).
     o InertMessageSvc: as the TBBMsgSvc, it manages the printing of the messages in
     a multithreaded environment.

    The CPUCruncher is not a component dealing with concurrency, but a useful
    entity to test it. It's an algorithm that simply wastes cpu.
