In a grid environment a Node is the place where the jobs are executed. There will be a Conductor node and multiple grid nodes which are executing in parallel to make the processing faster.

If the number of nodes are increased it increases the Parallelism of the job and hence the performance.

Nodes are like processors . The more number of it, faster the job. Each node will be given each instance of the stages of the job and run parallel to make job efficient.

A basic answer I have in mind is for load balancing/performance. For example, you can group x number of jobs to nodeA, and another group of jobs to nodeB. This way your jobs are not using just the default node. You can do this by setting your $APT_CONFIG_FILE for each of your jobs.

Just don't get confused with the term Node Vs Processor. A processor can have 1 or more nodes.

Nodes are referred as resources. If a job is running in a single node that means job is running on single system

Node is just a process. Its a logical thing used to increase the efficiency of the jobs by running them in parallel just like multi processing in operating system. Each node processes may run on the same processor or different processors.
