If the cluster is running MPI codes, then perhaps measuring the interconnect (x in brief mode and X in detailed mode) is important. This could also include Lustre [7] if you are using it in your cluster, as well

Applying these lessons to HPC, you might ask, "how do I tinker with HPC?" The answer is far from simple. In terms of hardware, a few PCs, an Ethernet switch, and MPI get you a small cluster; or, a video card
