Energy to Solution Best Practice Guide
Measuring energy to solution isn’t just more complicated than measuring time to solution, it’s also less familiar and less top of mind for most users. Hence, CEEC has published our experience and some best practices to help the EuropeanHPC community learn more about measuring energy to solution across systems and applications.
