Performance does matter in HPC but they tune for performance in a different way, not by the developer being smart really but by the language (read fortran) being dumb, in particular, easy to slice up for the compilers that are honestly decades old.
- eigenspace 5y ago> not by the developer being smart really but by the language (read fortran) being dumb, That's definitely a valid approach, but it's far from the only one employed in HPC.
- pjmlp 5y agoModern Fortran is quite smart, including modules, OOP and generics support. Also another wannabe replacement, Chapel is relatively smart, trying to mix Fortran productivity for HPC code with Rust like memory management.
