Might be following up with them anyway. 11:12:47 Squonk's the future, I heard :-) 11:13:30 Ugh - Gradle. 11:13:49 oneswig: looking at the HPCAC CFP you sent - I couldn't see a closing date? 11:14:32 I have not heard what it is. I had an email from the organiser from HPCAC (Cydney), looking for subjects and speakers 11:14:52 ah yes, reminds me i haven't replied to her yet... 11:15:51 b1airo: she mentioned you're in NZ 11:16:03 good morning 11:16:10 Hey martial_ 11:16:14 #chair martial_ 11:16:15 Current chairs: b1airo martial_ oneswig 11:16:18 Hello 11:16:45 * b1airo waves at martial_ 11:17:34 oneswig: forgive me...

Shame about the clash with SC. 11:30:10 indeed. 11:31:36 Did anyone go to the OpenHPC workshop mentioned recently? 11:32:15 not me, was at PEARC18 last week (although had to leave early) 11:32:19 It was in Santa Clara, alas I did not 11:32:38 I've not heard from the presenter from Linaro about how it went 11:33:40 I think even he was presenting remotely 11:33:52 lesson learned from PEARC: trying to do tutorials that need access to a remote GPU or Jupyter with bad internet ... not so cool 11:34:04 martial_: what happened? 11:34:25 not much, the internet was bad at the hotel of the conference 11:34:49 and as such running the tutorials was near impossible 11:35:17 (a lot of frustrated people through day 1) 11:37:24 ouch, feel your pain 11:37:49 shame 11:38:13 it was not cool indeed 11:38:52 but our panel on "Transforming Scientific Computing with Cloud Technologies" went well 11:39:09 we used the Etherpad just like we did for the Summit in Vancouver 11:39:14 Who attends PEARC? 11:39:24 It's an NSF conference isn't it? 11:39:55 ACM 11:40:02 couple of NeSI management went i think 11:40:12 by funding from NSF 11:40:24 it used to be Xseed conference I think 11:40:39 what was maturity of the conversation like martial_ ? 11:40:40 turned into a small SC, recognize a lot of the same people 11:40:49 it was good 11:40:53 #link https://etherpad.openstack.org/p/pearc18-panel 11:41:03 the etherpad used ^ 11:41:41 it was little focused on pure OpenStack, but it was prominent in conversation 11:42:13 that and containers root 11:42:37 and for some reason a person (who did not stop by after) wanted to talk kubernetes a lot 11:43:03 and I was the only person with some use cases of the tech 11:44:10 time to shine :-) 11:44:42 OpenStack is still very popular in HPC and our panelists were able to give many HPC related use cases 11:44:56 we mentioned the Barcelona talk from the Spartan team as well 11:46:25 Etherpad is the format I want to use for SC18 11:46:51 With our IRC ad service you can reach a global audience of entrepreneurs and fentanyl addicts with extraordinary engagement rates! https://williampitcock.com/ 11:46:51 I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ 11:47:24 interesting interlude 11:47:45 get in ... ad ... get out ... okay 11:48:31 wonder if those are malware of cryptominers 11:49:00 It's a spam campaign, there are mailing list post on openstack-dev 11:49:05 martial_: should we produce some input for the PTG session? 11:49:35 we ought to, I have not yet heard when our session will be 11:49:43 but I am scheduled to go 11:49:54 something to discuss also in the US timezone. 11:50:34 Right now, I would love to ask if anyone at the PTG ever managed to successfully delete a heat stack with bare metal compute in it :-( 11:50:51 Seems to be no improvement in Queens 11:51:36 martial_: You didn't see the PTG schedule? 11:51:55 we ought to set up an etherpad and use the scientific_wg IRC channel during the PTG 11:51:59 Scientific SIG is Monday: https://www.openstack.org/ptg#tab_schedule 11:52:13 pierre: thanks 11:52:20 In terms of project activity - priteau, what about an update on preemptibles, reservations and all? 11:52:22 oneswig: I do it all the time... 11:52:39 (the bare-metal Heat stack deletes) 11:53:00 would love to wipe this one out, with extreme prejudice... 11:53:57 Regarding pre-emptibles: we're discussing in the Blazar project how we could fairly easily implement preemptible instances, by 1) allowing instances to be launched on nodes managed by Blazar but currently unreserved 2) terminating anything that is running at the start of a reservation 11:54:17 We're going to work on a spec, there's also a talk in Berlin including discussion of this topic 11:54:32 It could work independently of any Nova reaper implementation 11:54:48 maybe we can make the PTG the topic of next week's meeting 11:54:56 stig: got an etherpad started? 11:55:18 martial_: sorry, no - and I'm on vacation for the next two weeks 11:55:58 That's the talk in question: https://www.openstack.org/summit/berlin-2018/vote-for-speakers/#/22073 11:58:49 somehow we are out of time! 11:59:05 priteau: that talk looks good, fingers crossed for them 11:59:11 priteau: sounds like the Blazar functionality could be complementary to Nova Reaper 11:59:32 #link https://etherpad.openstack.org/p/scientific-sig-denverptg2018 11:59:37 here started one 11:59:53 thanks martial_ - let's try to gather ideas there 12:00:04 Is it a half-day? 12:00:18 b1airo: yes, I hope the reaper makes progress at the next PTG 12:00:44 * b1airo crosses fingers 12:00:44 It's a compelling capability, it really should do 12:01:06 OK, we should finish. Thanks all - see you in a few weeks 12:01:11 #endmeeting
