Productivity before performance.

HPC is more performance before productivity.

Most programming is sequential. There is no general method to change a
sequential program into a parallel one, and even the methods for
specific problems domains that are there require a high programmer
skill/experience level, and is then still laboursome and risky.

This makes workers more expensive and takes longer training, with
potential retraining needed for a different problem domain.
