The number of NODES increased then we have to increase the NUMBER OF CPUs is to increased? (Y/N)

Number of Nodes interms Number of CPUS in the current system so if you increasing the Number of nodes means increasing the Number of CPUs on the serevr. Isn't It?

The number of Nodes in an APT_CONFIG configuration and the number of CPUs on a system have absolutely nothing to do with each other. You can run a 100 node configuration on a single CPU system or a 1-node configuration on a 64 CPU system.
The configuration file tells DataStage how many levels of parallelism to run a job with which directly affects how many OS level processes you will have running. Having hundreds of PIDs fired up and running on a single-CPU system will most certainly make the system run slowly and at some time will overload the machine so that things start failing due to timeouts, but if it doesn't fail then the results will still be identical to running the same job and configuration on a 2,4,8, or more CPU system.
