Putting It Together.

Figure1 shows an example of a system with one server and four clients (two workers and two watchers). The work engines request work data from the work managers, compute them, and then send result data back to the work manager, which then places these into the result pool. The work and result pools are shared by the work and watch managers, allowing the watch manager to watch the progress of the computation and inform watch engines of such things as new results and statistics.
