This is a simple gcc plugin that draws a graph of the OpenMP constructs of a progam using graphviz. The main motivation behind this was to investigate what kind of information about OpenMP constructs can somebody get at compile time using gcc. An output example can be found here: http://www.cslab.ece.ntua.gr/~kkourt/var/for-test.png TODO: - Use the callgraph to get more information about the (possible) nesting of constructs. For example, we could draw edges from calls inside OMP constructs to functions that contain OMP constructs. Try to do this at link-time, also. - combine with profiling Requirements: - gcc-4.6 (+plugin development files) - libgraph from graphviz -- Kornilios Kourtis, [email protected]
