Melody is a lightweight parameter search and optimisation tool originally designed to support searching and optimising over the performance landscape of software. In particular, it is being designed to support code composition options (loop ordering, loop fusion etc), code compilation and link options (compilers and compiler flags) and code configuration options (tunable parameters such as a cut off radius, or preconditioner). However Melody has been written in a relatively generic way so can be used to search over, or optimise any search space.

Melody takes its name from the fact that optimisation is often called tuning and most good tunes rely on a great melody!
