Such core with 12GB of +memory are just "peanuts" in an environment with plenty of developers. Half +of that machine (e.g. with a core i7 985X, or AMD 1055T) is actually a +medium/top PC which you can build in your home. + +So you have to distinguish automatic rebuilding of the distro, which +operates on "working" packages from the svn, from new packages built from +the first time. The first task of a massive rebuilding is a automated task +which can be done sequentially (but 1 day is only for the main, then there +is contrib, then you have 2 archs, 32 and 64bits, and backports); the second +task instead has a lot of stop and go. If for instance a build goes wrong +because a packager couldn't test a parallel build in his own development +machine (or because the number of cores is different and you get race +conditions problems), and have to redo the work, but in the meanwhile the +building system is busy, or has other kind of problems (wait for library to +propagate, etc.), then he have to spend a lot of time fighting against the +system and babysitting a package, rather than concentrate on packaging or +developing. And for sure he would fly away (packagers are not of iron with +infinite patience). + +Also consider that the phase of LZMA compression of the RPM building won't +operate in parallel. + +Bye +Giuseppe. +-------------- next part -------------- +An HTML attachment was scrubbed... +URL: </pipermail/mageia-dev/attachments/20100927/d8e0e4e8/attachment.html> +</PRE> + + + + + + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="000289.html">[Mageia-dev] Will this work for a build system? +</A></li> + <LI>Next message: <A HREF="000283.html">[Mageia-dev] A comparison of forum software from a security POV +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#293">[ date ]</a> + <a href="thread.html#293">[ thread ]</a> + <a href="subject.html#293">[ subject ]</a> + <a href="author.html#293">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-dev">More information about the Mageia-dev +mailing list</a><br> +</body></html> |
