The Athlon CPUs (especially those beefore XP) seem to be able to run applications much faster when applications are optimized for the CPU (well, not that very much but anyway). Therefore I have come up with a grand ambition of building every binary package available in Debian to be rebuilt with Athlon optimization. This project started very quietly, and I am continuing with this project very, very quietly... under the veil of secrecy.
In the beginning, it was a joke. But as things progressed and my tools advanced, those little matters materialised to be more real. The whole things look like it is possible
This has been started up since sometime in the Springtime of 2001, and it has grown gradually to reach some kind of usable state. The problem I can see now is the fact that some packages cannot be compiled. Also to evaluate the meaning of this project, I need to complete the system actually before I can benchmark it.
Following diagram is the graph representing the time it takes to build each package. This was taken on the whole-packages build run which finished on 29 May 2002.
None, yet, really.
Not much to use other than pbuilder and other suites.
Currently, Debian system has a system for choosing libraries optimised for certain architectures, as used in atlas libraries. However, there is no systematic way of using optimised binaries.
This project will hopefully create a generic way of generating and handling such binaries, destined to creating a opt-in way of optionally making binaries automatically recompiled for optimisation.
The same source file and same /debian/rules file will be ran with different environmental variables, and the gcc and g++ commands being replaced with the optimal binaries for building for certain arch. This should hopefully unload the burden from some packages, and will possibly improve the general status about Debian packages being optimised.
This project is crawling slowly, because I do not have the hardware dedicated to this project, and this project requires a lot of attention and hard work to keep on running. It certainly wears a lot of hard disk surface.
