heller: I guess it's not possible to run even a subset of our tests on circleci? it seems to have only two cores per instance...
EverYoung has joined #ste||ar
EverYoung has quit [Ping timeout: 240 seconds]
<heller>
simbergm: yeah ...
<heller>
simbergm: circle-ci is just too slow
<heller>
simbergm: I really would like to utilize our resources more efficiently. Everyone one of us has a large variety of different compute resources available ... it's a shame that we don't use those...
EverYoung has joined #ste||ar
<heller>
simbergm: and yes ... I currently spend most of time looking into failures coming from PRs where nobody actually cared to run the unit test suite...

<simbergm>
heller: yeah, it's not good (and I'm guilty of wasting your time as well...)
<simbergm>
I was asking because the cscs ci stuff is progressing very slowly
<heller>
yup...
<simbergm>
how much du you know about buildbot on rostam? would it be possible to even build and test a single configuration there for each branch?
<simbergm>
or reduce the number of supported configurations
<heller>
simbergm: buildbot on rostam uses an old buildbot version
<heller>
the problem with buildbot really is to integrate other machines not located on the LSU network
<simbergm>
right, so we wait for cscs :/
<heller>
or implement something on our own ;)
<heller>
I have machines and public IPs to run the basic service on
<heller>
I just need the technology to dispatch to the different machines
<simbergm>
hmm, so what we should get from cscs is jenkins which seems to have the option to accept results from remote machines, then we could use cscs and rostam for testing and I imagine that should be enough
* zao
perks up
<simbergm>
jenkins is open source though, so you can set that up if you want ;) but probably better to have cscs manage it
<heller>
yeah, then you only have to have jenkins slaves running on the machines you include
<heller>
does the CSCS jenkins support machines that are *not* in the CSCS network?
<simbergm>
well, I think at the moment not and this is one of our requirements to them
<simbergm>
we have a meeting next week which is supposed to get this going somehow
<heller>
ok

hkaiser: yt?
<hkaiser>
jbjnr: here
<hkaiser>
g'morning
<jbjnr>
hi
<jbjnr>
if I have a futures_factory(blah) and I call, fact.apply(stuff) and then return fact.get_future() - that creates a task for me - does it go onto the pending (ready) queue or one of the staged/suspended queues -
<jbjnr>
if I know it has no futures, it is ready to run - can I add a flag to say so?
<jbjnr>
(not sure if I need it, didn't look closely yet)
<hkaiser>
hold on, checking
<hkaiser>
jbjnr: I'm almost done with the changes we discussed, btw - things should get better for you there
<jbjnr>
thanks

david_pfander: How is gregor getting on in Louisisna? Did you find somewhere for him to live?
<david_pfander>
jbjnr: Hi John, only heard good things from him. He is making good progress at converting/porting the remaining OctoTiger kernels
<jbjnr>
hkaiser: great - I'll add an apply that takes an extra flag if necessary - if my experiments work and show it helps.
hkaiser has quit [Read error: Connection reset by peer]
<jbjnr>
david_pfander: good to hear
hkaiser has joined #ste||ar
<david_pfander>
jbjnr: BTW, will there be access to Piz Daint for some OctoTiger performance runs early next year, or do our accounts expire in the near future?
hkaiser has quit [Read error: Connection reset by peer]
hkaiser has joined #ste||ar
<hkaiser>
jbjnr: we could also extend future_factory to support executors, that puts it back into your hands
<jbjnr>
david_pfander: the hpx test account already exired and when I asked to renew it - I got no reply - so I'd better ping them again
<jbjnr>
hkaiser: interesting idea. I will look at that.
<david_pfander>
jbjnr: I haven't done any runs lately, but I at least can still login into daint and tave. Would be extremely useful if those machines remain usable for Gregor and myself :)
<jbjnr>
I'll look into it
<david_pfander>
jbjnr: thanks a lot!

hkaiser: please do add executor support if it doesn't take much work - that will allow a wide range of extra customizations that might prove useful in the future (pun)
<diehlpk_work>
--hpx:print-counter=/threads{locality#0}/idle-rate What is the replacement for this counter?
<hkaiser>
diehlpk_work: you need to enable this counter at configure time

<hkaiser>
jbjnr: will do - still some problems - but I'm closing in
<hkaiser>
jbjnr: also, Ihave the futures_fatory changes implemented on that branch as well
