### Development and optimization of ESM dwarfs
|
|
|
ESM dwarfs (or mini-apps) are concise blocks of code comprising key algorithms and mathematical kernels, abstracted from their original code base. They offer the possibility of exploring improvements and optimisations in a a focused way, avoiding the complexities of working with a full model system. They naturally encourage to work within the concept of separation of concerns, by facilitating experimenting with low-level libraries, hardware-specific programming models and optimisations, and high-level abstractions to encode them.
