This version is stable for public release. The major enhancement over previous versions is the new structure.yaml output of optiwise analyze, as well as the optiwise gui command.
structure.yaml is a file detailing the profiled program's runtime structure, in particular the loops and function calls that exist and their nesting. For example, it encodes which loops call what functions, and the relative IPCs and execution times of each.
optiwise gui generates a series of HTML and JavaScript files that give an interactive interface for viewing the results of optiwise analyze including source code listing, assembly code listing, control flow graphs and a program structure graph.
