The number of logical nodes in a config file and physical CPUs in a system are independant. Simply put, the number of logical nodes just defines how many processes are used, then the OS determines how these processes are distributed across the available hardware.

Hi ArndW,
I want to understnd that how the number of logical nodes in a config file and physical CPUs in a system are independant.
for eg if i have 4 CPU system how many nodes can I define in config file.
How it will impact the performacne if I define 2,4 and 8 nodes in config file.what will happen in each case.
Your reply on this will help me understand the concept of nodes and config file.
Please help.
Thanks,
Ankita

Performance - whatever you mean by it - is a simple supply and demand equation. You can run as many nodes as you like if each of them is doing hardly anything. But you can only run a tiny number of jobs that demand huge resources. A parallel job will create approximately N * (M + 1) + 1 processes, where N is the number of nodes and M is the number of stages (operators). Each of these will demand resources from your system.
