Atually, conductor, section leaders and players should not be thought of as an "advanced" topic, but one that every developer should be aware of nor is it premium content since it can be found in the Parallel Job Developers Guide in Chapter 1.
If you do not know where these documents are they are under C:\IBM\InformationServer\Documentation\bookshelf.html (at least that is where they are for 8.x)
For every job that starts there will be one (1) conductor process (started on the conductor node), there will be one (1) section leader for each node in the configuration file and there will be one (1) player process (may or may not be true) for each stage in your job for each node. So if you have a job that uses a two (2) node configuration file and has 3 stages then your job will have
1 conductor
2 section leaders (2 nodes * 1 section leader per node)
6 player processes (3 stages * 2 nodes)
Your dump score may show that your job will run 9 processes on 2 nodes.
This kind of information is very helpful when determining the impact that a particular job or process will have on the underlying operating system and system resources.
