Answer / prasad
The Question was not clear....
The answer given by Nagraz also correct if u take the node
information from a configuration file but according to the
datastage archietecture there was again three nodes.
They are
1)Conductor Node:-
which contains the intial framework process of the Datastage
2)Section Leader:-
It was useful to manage the communication between the
players
3)Players:-
Those are useful generating the connection between
different players and also done the all processes inside
the Players only...

Answer / sri
We are having three types of nodes.
Conductor node, Section leaders & Players.
Conductor node composes the score and create section
leader's process and start up the process.
Section leaders are present only one per node. Section
leaders manages up(conductor node) & Down(players)
communication.
Players : The actual process associated with players. They
establish connections to other players. They will be clean
up after completion of their process.

Answer / huma
There are only 2 types of nodes.
1) Physical Node (that uses actual physical resource/CPU)
2) Logical Node (that uses sub-operator CPU processes and is a sub-set of a physical node).
Conductor node is an additional name given to the node where the parallel engine process starts in a job.
Most of the people have mentioned section leader and player nodes but those are the processes not nodes that are used to communicate the processing between different stages and nodes.

Answer / nagaraz
THERE R 4 TYPES OF NODES.
1). NODE : NODE REFERS TO LOGICAL PROCESSING UNIT AND NOT
PHYSICAL NODE, THE DEFINE ALWAYS STARTS WITH NAME.
2). FAST NAME : THE FIRST NAME FOR THE NODE IN THE NODE
INFORMATION IS ITS NETWORK NAME ON THEFASTEST NETWORK.IN AN
MPP, MANY TIMES MACHINES ARE CONECTED WITH FAST NETWORK
CONNECTIVITY SUCH AS FIBER OPTICS,ETC.
3). POOLS : VARIOUS RESOURCES CAN BE GROUPED USING KEY WORD
POOL.GROUP IS USEFUL WHILE USING POOL.
4).RESOURCE : THIS KEYWORD ALLOWS YOU TO SPECIFY THE
RESOURCES AVAILABLE
