Intro to Parallel computing

One of the core values of computing is the breaking down of a big problem into smaller and easier to solve problems. In some cases, the steps required to solve the problem can be executed simultaneously (in parallel) rather than serially (in order). HPC cluster is not just about fast processors. It is multiple processors working together simultaneously. Therefore it makes sense to utilise parallel computing in the HPC environment, given the access to large numbers of processors.
