Some time ago I wrote a brand-new, MPI-based, parallel data post-processing tool for analyzing the output of our CARP simulator. I have now uploaded it to github here. It is modular in design (as the name implies) and it is easy to build custom tools with the modules.
There are a couple of things I really love about this library and tool. First, it is written so that parellelizing the work is easy and relatively transparent. Second, because it is parallel, it allows the analysis of really large IGB (CARP output) files in a short period of time, given appropriate hardware such as a cluster.
If you have any questions about using it please don’t hesitate to ask.
