 <p>In this context, a cluster is a collection of computers (often referred to as "nodes"). 
 They're networked together with some shared storage and a scheduling system that lets people 
 run programs on them without having to enter commands "live".</p>

 <p>Some researchers have programs that require a lot of compute power, like simulating weather patterns or the quantum behaviour of molecules.</p>
 <p>Others have a lot of data to process, or need to simulate a lot of things at once, like simulating the spread of disease or assembling parts of DNA into a genome.</p>
