Dune mid-term review

Hello!

Last week was the mid-term review for the GSoC. Because of this, I spend more time polishing and completing existing things than adding new ones. The biggest was documentation, I added docstrings to all the functions I’ve written since the start of coding. This should hopefully make it easier for everyone else to see what I did, but more importantly to extend it in the future.

This was, however, not all. Dune-perftest now has a couple (= two) example programs, written in C++ using the DUNE libraries. One is mostly empty and basically just measures the time needed for MpiHelper initialization, while the other works with matrices. Such programs will be used for monitoring the performance of DUNE itself. In order to build these C++ programs, I had to use the DUNE build system, based on autotools. I probably spent far more time than I should have on this one. As mostly a KDE developer, I am only used to CMake. I know that DUNE already supports CMake, and if I understand it correctly a complete move is planned, but at the moment I will include both.

There are no new screenshots, because graphically nothing has change since the last post. The actual generation of templates is somewhat improved, and the page (and graph) only shows data for the same command. I’m pretty happy with how both Bootstrap and Dygraphs turned out, I will probably redesign the page a little, but the graphs look good enough to me. However, I will add more information, starting with the memory footprint.

Now that the first half is over, I have to start planning ahead. My short-term goals are more automation and some statistics. More automation means you should be able to test multiple programs with one command. A couple more example C++ would help a lot for testing this. I will also make it possible to define both compile and run commands and have those associated with the same program. DUNE is mostly a template library, and these can often cause very long compile times. Once testing is automatic enough, there will be more data, so a need for meaningful statistics will arise. These can be basic enough, identifying outliers and general trends will be my first priorities.
