Difference between Compute Node and Compute Cluster

Question

I have to give a presentation on Super Computing and I came across this pdf http://yuva.cdac.in/YuvaII/YUVA_2%20leaflet.pdf. As mentioned in page 2 what is the difference between Computer Node and Compute Cluster.

Thanks

Solution

In this context a Cluster is a group of Nodes.

Note that it tells you in your linked leaflet that each Cluster is (upto) 225 Nodes.

(Very) Basically, the Nodes do the computing work, and the Cluster allows them to work together as one.
