       -## Intro
       +Numerical models are used extensively for simulating complex physical
       +systems including fluid flows, astronomical events, weather, and
       +climate.  Many researchers struggle to bring their model developments
       +from single-computer, interpreted languages to parallel high-performance
       +computing (HPC) systems.  There are initiatives to make interpreted
       +languages such as MATLAB, Python, and Julia feasible for HPC
       +programming.  In this talk I argue that the computational overhead
       +is far costlier than any potential development time saved.  Instead,
       +doing model development in C and unix tools from the start minimizes
       +porting headaches between platforms, reduces energy use on all
       +systems, and ensures reproducibility of results.
