Yes. It always strikes me if I see existing benchmarks, all focusing on some image stuff or GEMM.

The idea of a device database is of course not new, but on the other hand we have to keep in mind that there must be good reasons why it is so hard to really put that into libraries. Even autotuning approaches at installation time (cf. ATLAS) is a burden. Back in 2010 we tried ViennaProfiler, which is supposed to provide just that as a standalone database, but even that turned out to be pretty hard to manage in practice. The important point here is 'in practice'. Such a database needs to be maintainable, robust, and all integrated. We cannot expect our users to carry a separate database-file (XML, sqlite, etc.) around, this needs to be in the binary already. As such, I don't know the details about cTuning and how this would interact. It would be great if you can work out some details on how this could be done, so that we can then evaluate which path is supposed to be most fruitful for the GSoC project. > -> Filling the database with as many devices as possible. Yes, this is what we need and probably the most important item of the three. I'd rather have - although awful - a bunch of data jumbled all over the place and in different formats rather than having a great framework for everything without any data in it.
