Understanding DataStage configuration files.

I have a generic doubt on configuration files. I always get confused to understand the underlying system is SMP, MPP or SMP clustered. I have gone through parjdev.pdf to understand this -

I will understand the configuration file is SMP based on below -
Nodes have same fastname & different pools.

I will understand the configuration file is MPP based on below -
Nodes have different fastname & different pools.

I will understand the configuration file is SMP clustered based on below -
One or more node share the same fastname & have same pools.

Is my understanding with the configuration files is correct also please share any other angle to understand these configuration files better based on underlying hardware architecture?

Since SMP environment is "share everything" pools don't really help all that much. You're right about the processing nodes. It is not actually necessary to have any pools, node or disk.

I have seen some places resources also organized as a pool in the config file. I believe in SMP configurations those resource pools also get shared. Am I correct in understanding?

Even some remote CPU will be connected the grid using high speed link and will have a different fastname, which will still form a SMP.
