Re: How to put our new package (for free) into Karmic 9.10

I believe you will only need to upload the source package to REVU, from there the build server(s) should be able to build the the binary packages. I've included the ubuntu-motu mailing list, who would be able to give you much better answers, I'm not a MOTU myself yet and I wouldn't be able to give you the quality of answers that you would be able to get there. -Jonathan -- Ubuntu-motu mailing list Ubuntu-motu@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-motu

REVU is a tool for publishing proposed source packages for review by MOTUs and the community - no automatic builds are performed on REVU uploads. REVU is definitely the right place to be publishing a new source package you would like advice and comments on, but asking specific questions either on this mailing list or on the #ubuntu-motu IRC channel is also advisable. In particular, why does your package need so many platform-variant builds? Mostly Ubuntu only differentiates between x86 and x86_64 CPU architectures. Our package is very processor dependent. It means we have several different algorithms depending on amount of CPU cores, or processor core and on the amount of L1/L2/L3 cache. It is really highly commercially tuned. We decide to share it in Ubuntu community, so, it is the main reason why we should build several versions depending on hardware. We may install CPU detector in sources, but it will force user to compile this package, that might be not very convenient. Max. Ilgis -- Dr. Ilgis Ibragimov Vice-President Elegant Mathematics Ltd. Hanauer Muehle 2 66564 Ottweiler-Fuerth Germany Tel: +49-163-7414473 My original message was: Hi, our company Elegant Mathematics Ltd. uses Ubuntu last 3 years and want to contribute in Ubuntu for free as the respect to Ubuntu community. We have several iterative linear system solvers: CG, BiCGStab, GMRES etc., implemented on CPU and GPU with massively parallel support, single/double/quad precisions, real/complex arithmetics, and these solvers were commercialized by Elegant Mathematics since 1992. We would like to provide important part of these solves (especially with CUDA GPU support) for free for all Ubuntu users. I know that Ubuntu have already several similar packages like superlu, umfpack, but these packages do not support GPU computing. Using GPU we can improve up to 50 times computational speed achieving 250 GFlop/s on GTX 260, and our achievements are listed on NVIDIA Corporate site at http://www.nvidia.com/cuda We may provide the following two packages: 1. Open Source (GPL) software with preconditioned iterative methods and single/double/quad precision for real/complex arithmetics to be incorporated into main Ubuntu repository; 2. free for Ubuntu users library for NVIDIA GPU for the same topic to be incorporated into partner or multiverse release since our algorithms then depend on NVIDIA proprietary drivers. The questions: 1. how to proceed to be listed with this package in Ubuntu main repository, and to whom can I refer? 2. These packages are ready now, can we expect if we will work fast, enter to the 9.10 release?

We may install CPU detector in sources, but it will force user to compile this package, that might be not very convenient. I presume this detection isn't done at run-time for performance reasons? I would naively expect the library to perform this detection once at initialisation and from then on call into the appropriate system-specific code, but there's probably a reason you aren't already doing this. As long as all these different build configurations can be manually configured (ie: don't automatically tune for the system they're being built on) it would be possible to build all these different binary packages; it'll just be a bit of a pain.
