<simbergm> heller_: cool
<simbergm> so that's running on that whatever-it-was-called-thing with free slow instances and occasional access to bigger instances
<simbergm> ?
<heller_> simbergm: the cool thing here is, that gitlab runners are in addition able to run over ssh
<heller_> yeah, during tests, the bigger instances were almost always available
<simbergm> what do you mean by run over ssh?
<heller_> that we can target any machine we have access to
<simbergm> ah, as in not over http or something else annoying like that
<heller_> right
<heller_> so the runners on the cloud provider use docker-machine
<heller_> to autoscale
<heller_> also: I set up a small test repository to play with the setup
<heller_> so, in theory, this would allow us, to add new build configurations with PRs, for example
<heller_> and having that nicely integrated
<heller_> and less messy ;)
<heller_> this could replace circle-ci, buildbot and pycicle
<heller_> all integrated into one tool, which we don't have to maintain, we'd only have to maintain the infrastructure
<heller_> packet also offers servers with V100s and ARM64...
<heller_> so, what do you think?
<simbergm> heller_: I think it sounds wonderful
<simbergm> do we know how much compute time we could get realistically? to build 20 open PRs with a few different configurations :/
<simbergm> although I guess your point is that we can use rostam as well ;)
<simbergm> does gitlab have an option to only run ci on demand?
<zao> So how does this fit into my vapourware test soaker? ;)
<heller_> zao: you can define cron jobs to run pipelines ;)
<heller_> simbergm: weee!
<heller_> simbergm: regarding compute time: Yes, we can use rostam and emmy and piz daint and what not ;)
<heller_> simbergm: let's start small and see how we can expand...
<heller_> simbergm: with on demand, you mean not automatically per PR, or when you have a branch, you want to check if it works?
<simbergm> heller_: goody, I have the same concerns as hkaiser about community being on github etc, but you were planning on having a mirror to start with? I have to say I do quite like gitlab
<heller_> I like gitlab very much as well
<heller_> simbergm: currently, it is setup to mirror github
<simbergm> yeah, essentially only build once someone tells it to build to avoid unnecessary builds (e.g. WIP PRs)
<heller_> yes, you can skip WIP PRs
<heller_> you can even tag them accordingly in the gitlab UI ;)
<simbergm> or only build one configuration to start with and then build all once it's clean as a last check
<simbergm> for example
<heller_> simbergm: https://github.com/STEllAR-GROUP/hpx/pull/3581 <-- this is using the mirror
<heller_> simbergm: I think it would already be quite an improvement if we just replace circle-ci as a first step
<simbergm> I guess it can't report to github? if it can I'm sold
<heller_> it already does ;)
<heller_> look at the PR
<heller_> "ci/gitlab/gitlab_runner — Pipeline failed on GitLab Details"
<heller_> first line for the checks
<simbergm> oh... well then :)
<heller_> "just" need to finalize the yml...
<heller_> btw: gitlab even comes with its own docker registry ;)

<hkaiser> heller_, simbergm: I'm still not fond of moving away the main user-facing repo from github
<hkaiser> if we can do everything through the (automatic) mirror, let's do it
<heller_> hkaiser: I didn't suggest to move everything away
<heller_> just the CI part
<hkaiser> k
<hkaiser> fine by me
<heller_> hkaiser: however, as far as I can tell, gitlab is gaining more and more traction
<heller_> but I couldn't care less where the repo is actually hosted...
<heller_> however, I do think that gitlab offers a better UI than github

<heller_> simbergm: can we get rid of the rostam docs builder?

<simbergm> heller_ definitely! Can you do it? Can I do it?
<heller_> simbergm: I can do it, just wanted to check
<heller_> done.
<heller_> oh shit
<heller_> sorry for the disruption ... didn't see that there is still a build ongoing :(
