cluster computing is all about scale.\u00a0 Doing computations at scale allows a researcher to test many different variables at once, thereby shorter time to outcomes, and also provides the ability to ask larger, more complex problems (I.e. larger data sets, longer simulation time, more degrees of freedom, etc.)\u00a0<\/span><\/p>\n<p><strong>Please Note:<\/strong> The FASRC research clusters <a href=\"https:\/\/docs.rc.fas.harvard.edu\/kb\/academic-use\/\">cannot host class accounts and academics <\/a>due to FERPA and other requirements.

Scaling computations to take advantage of a cluster may require changes to how the computation is configured and executed.\u00a0 As cluster-computing is a shared resource, many factors affect performance including other computations on the same compute nodes competing for memory, storage, and network. In addition, due to the nature of research that is being performed, it isn\u2019t always well understood by the end user how scaling out their computations on a cluster will differ from performing them on a single device in terms of resource requirements (cores, memory, time, data storage), as these are managed in a different way on a single device.\u00a0 It is always best for researchers to test smaller data sets and batches of tasks before submitting hundreds or thousands.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">At FASRC, availability, uptime, and backup schedule is
