[opensuse-buildservice] build power
Hi all, In a couple of weeks we expect a new server rack, sponsored by SUSE, to arrive. It will bring enough build power to solve the long waiting many of you are experiencing. See http://news.opensuse.org/?p=15739 for details. In the mean time, cleaning up unused packages and projects in your home always helps us save some cycles! Our binary delivery server is also getting full and that, too, will need a solution. Cleaning up only gets us so far. Help finding a new server is welcome, Adrian can probably tell you what we need if you ask. Remember, this service depends on support from sponsors and we can use more help. Cheers, Jos

Jos, This is a highly welcome gift to the community. Much appreciated. Only one thing left to say: " THANK YOU SUSE ! " Dominique -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

I don't want to sound ungrateful, on the contrary, but aren't those 5.4k rpm drives a bad choice? A great many times builds are limited by IOPS, in my limited experience. That means, in those many cases, those low-rpm drives will be a pretty narrow bottleneck. Has OBS worker load been analyzed to get to the conclusion that 5.4k rpm drives are a good choice? I'd be interested on seeing that analysis, since at some place I used to work we had a mini-farm that could benefit from some of that insight (ie - I'd like to forwarding that to my former sysadmin ;^) ) -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

We took the sponsored system just "as it is" - if we got the possibility, we probably would even not use any local hard disk and have everything in the (bigger) RAM of the machine. Now we will see how many workers can be started in parallel - and afterwards divide the available RAM and see if there is enough left to start the workers in a tmpfs image. If I had the choice, I would * use tmpfs for building * use SSDs for the OBS cache as we boot the workers via PXE, there needs no pre-installed OS on the hard disks. And there is nothing that can replace RAM - beside more RAM ;-) I hope that answers your questions. In general you are right, but we take what we can get and will try to get the best out of it... ;-) With kind regards, Lars -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

IMHO, drop Ubuntu, Debian, Fedora, Mandriva, etc from build repositories. It will save a lot of power for *SUSE* OBS. Each of above distros has its own build system. -- WBR Kyrill

Yes, or simply disable all building/publishing for those repos by default, but allow manual "enable build / publish" -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

Yes, and many of our users come to us anyway, because we offer this service. They build their Fedora/RHEL/Mandriva/... packages which they are interessted in first place and are happy that there will be SUSE builds in addition. We would never get their attention at all if we would be SUSE only. And in the end of the day, the vast amount of our build jobs are SUSE builds anyway.

There is no repo added on a new project by default. And when you branch, you want to see if it breaks any repository. So, no, we will keep the other distros for sure. I want to make this clear here to avoid confusion and pushing developers out of our service. bye adrian -- Adrian Schroeter SUSE Linux Products GmbH email: adrian@suse.de -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

With respect to multi-threading, the source code could use improvements in some places. I have seen bs_srcserver using multiple processes (at least something!) at times, but that does not seem to be the case for bs_repserver or bs_sched. Especially the scheduler would benefit from it in cases where #cores >> #architectures to schedule for. -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

You're kidding, right? The source server is a web server, it'll spawn a new process for every request.
but that does not seem to be the case for bs_repserver or bs_sched. Especially the scheduler would benefit from it in cases where #cores >> #architectures to schedule for.
That depends on if it's IO bound or CPU bound. If it's CPU bound, another option is to improve the code. We already do some of the heavy work in an XS module, be might want to move some other stuff there as well. In most of the cases it seems to be IO bound, though. Note also that the current version of the scheduler supports async src server requests, we might want to try that for OBS.
