[gentoo-user] Jenkins
Hello one and all, I want to first install Jenkins on a single multicore amd system, so I found this brief guide (which seems simple enough): https://code.google.com/p/godin-gentoo-repository/wiki/Jenkins What I also need is an example collection of code to run Jenkins-CI scripts on, sort of as a benchmark. I figure it would be best to learn about Jenkins by merely trying to follow/duplicate an existing (hopefully small) Jenkins CI project. Basically a monkey-see-monkey-duplicate sort of endeavour. This will also allow me to then duplicate the Jenkins-CI onto the gentoo mesos clusters (small right now) I have built to debug problems or issues with Jenkins running on a gentoo-mesos-cluster. Ideas on how to perform comparison (benchmarks) between the single multi-processor Jenkins-CI and the one on top of a cluster, would be warmly received too. After that is completed and stable, then I'm going to attempt to move other codes to this gentoo-mesos-jenkins-CI framework. Any suggestions are most welcome. James

Jenkins has no concept of cores, only executors. Each executor can run one build at a time.

This is different than make and just other build tools in general that I've worked with for other languages. So, to the point; when you add more build slaves with more executors, you will be able to run more builds in parallel and it will therefore be faster. This gets even more complicated since you can constrain builds to only run on certain hosts and various other complicated setups, but in general more executors means more builds in parallel means faster.

James My main suggestion is to not bother running a Jenkins cluster and stick with a single host setup unless: * You are building so many things that utilization is near 100% * You are targeting multiple platforms and therefore need multiple build hosts Alec P.S. I could not find any reference to parallel, threads, processes or anything else on javac's man page that makes me think it is easy to set the number of threads it uses.

Yes, I've used Docker on gentoo before. NO, it's currently un-installed and using docker for what I am after only complicates things at this point. This is not really a fair comparison.

I'm not sure it's possible to control this (someone feel free to correct me if I'm wrong), hence Jenkins does not care about cores and only about how many builds are allowed to run in parallel at once. I'll have to drill into javac a bit more, it seems. There is jenkins-bin on gentoo; it should (?) be a quick install and config. I'll keep in mind what you are saying, but my main goal is to find (CI) codes that I can run on gentoo-mesos clusters. Nothing about Jenkins is a critical need for me. Although, as a consultant I do routinely get asked about Jenkins experience, so just noodling around with it a bit is a good idea for me. So, to the point; when you add more build slaves with more executors, you will be able to run more builds in parallel and it will therefore be faster. This gets even more complicated since you can constrain builds to only run on certain hosts and various other complicated setups, but in general more executors means more builds in parallel means faster. AT some point, on a single multiprocessor system, Jenkins will slow down even it more resources are configured for it (overall system load, if nothing else)? AT that point, I can note the resources and apply those limits to the cluster and note the performance differences. Surely, a cluster with more resources will be able to do more (CI_Jenkins) work; so discovering those details is a primary goal of this endeavour. My main suggestion is to not bother running a Jenkins cluster and stick with a single host setup unless: Sorry, the cluster, is the main_goal, not Jenkins or CI. Buds at cisco are all very braggadocios about CI (Jenkins and others) on their mesos clusters. * You are building so many things that utilization is near 100% * You are targeting multiple platforms and therefore need multiple build hosts YES, that is exactly the ultimate goal. A CI cluster, open to friends, pals and customers (maybe). It's all about the mesos cluster, you should know that. P.S. I could not find any reference to parallel, threads, processes or anything else on javac's man page that makes me think it is easy to set the number of threads it uses. No surprise there. Configuring threads, cgroups, and memory resources is a hotly contested area of the cluster codes I have (am) working with. Forget bikeshedding, it Blood_shedding... especially now that RDMA is hotly being pursued by the many. Thanks for your insights, James

Obviously, this profile contains no at system packages. Which
appears natural for an embedded profile...
Obviously, one cannot obtain the profiles to other arches from the
data found in /usr/portage/profile, easily. Surely a front-end
would be keen for this.
Also, I had a friend on an embedded gentoo (arm) board verify that
the same 42 files for @system was installed on his arm board (eix
-e --system).
I surely hope that something (gui tool) convenient and robust
becomes available; maybe GLEP64 will help.
For embedded (any arch) I would expect that the @system would not
contain all the files necessary to compile code. After all, that's
really what cross-compiling is all about. I'm not sure a single
packages, such as busybox really contains the best/complete codes
that is needed on an embedded gentoo system, but that is a
different issue.
I also think there is room for another profile, between default and
embedded where the target is a single (or focused) build for
something like a sniffer, a data collector, a firewall, a bridge, a
router, etc etc to have less than the default profile and
specifically matched to a tuned (aggressively pruned) kernel for a
very specific and limited purpose. That said, I'm going to think
about this a bit more and marinate over the postings from Andreas
and others for a while longer to decide what I think it should
really be.
I also think there should be a well defined path of what and how to
migrate from embedded to minimized[focused] and default systems.
One could experiment for example experiment with running a gentoo
based firewall-router on an embedded gentoo system, a
minimized[focused] gentoo system and a default profile gentoo
system all with the same firewall-routers codes for cost and
security and performance evaluations.
Thanks to all for the excellent information and input! Sorry about
being dense, as now Andreas's posts make more sense, but also
highlight the shortness of breadth of gentoo's current profile
system. It's also a pig mess of code, ideas and old constructs,
imho. (note: nothing negative about the wonderful folks that have
maintained and extended profiles over the years, but, it is time
for a discussion and new architecture for the entire profile
landscape, imho. Maybe after Glep 64 is usable it would be a good
time to move forward on profile_modernizations..
Others comments are welcome.
James
The list of all profiles that can be chosen (for all architectures)
can be found in ${PORTDIR}/profiles/profiles.desc . There are other
profile-like directories under ${PORTDIR}/profiles, but these are
only used as parents for a complete profile, as would be listed in
profiles.desc. Most profiles do not change much, if anything, in the
@system set. The @system set contains much more than you would
probably need for a dedicated, embedded device.
