Also this is not just a hardware issue. Many HPC systems in academic research have very mixed workloads that are hard to optimise the design of a HPC system for. The majority of researchers have little interest or time to spend optimising their code, they are seldom have enough experience in programming or software engineering to know how optimise without assistance (in our case we pick out the worst system hogs that are affecting other users on our HPC systems).
