 Hi, everyone. So first, I would like to start with welcoming our one and only sponsor, Google Cloud. Thanks for hosting, for sponsoring this event. So yeah, my name is Abdullah, and this is Ricardo. Going to give a quick intro, welcoming remarks to our batch working group. So it's a half-day event, starting now up to 5 PM. We've got a really good number of submissions in our call for papers, lots of high-quality submissions. We really debated which ones can go in. Some of these presentations regretfully got dropped, but hopefully they will get another chance to have their presentations in future batch days. We've got a keynote speaker from Google. We have five full sessions of 25 minutes and three lightning talks. The goal of this batch day is really to shed some light on batch on Kubernetes. For some time, Kubernetes focused on service-type workloads, and we thought that might be a good idea to start organizing more and more events related to batch workloads. Give it a higher level status in the Kubernetes community. The call for paper invited talks related to high-performance computing, job management, and diverse types of communities, industry researchers from both research labs and universities. And again, as I mentioned, the goal is to expose work that tries to make Kubernetes a better platform for running batch and HPC-type workloads. Yeah, so yeah, thanks everyone for showing up first. And so the topics covered today, we try to also be as diverse as possible according to the submissions we got. But the topics initially set were kind of reports on different types of approaches for large-scale data processing and to try to set up and expose best practices in this area, not only in terms of performance, but also the cost versus performance. It was an initial goal to think about these things. People are looking at how to run spot workloads to improve their usage as well. But then the main topic is really the reports on how Kubernetes is being used for batch workloads today. And if you're involved in this area, you know there's quite a lot of options. So the goal is really to get everyone together in the same event and try to summarize the status and to work together on the next steps. So we'll have reports from both end users and things that they've been using to achieve these goals and also the projects and the different options that we have available. One thing I would like to highlight because we had, in some cases, double submissions to this event and to the main event. So the policies that people will keep their slot in the main event if it was accepted. But I would like to highlight a couple of talks that are quite interesting as a kind of compliment to what we are discussing here today. So the first one is on the volcano project. We also have a talk about volcano today, but they are incubation in the CNCF, so they actually have an intro deep dive as part of the maintainer track. Then we have also on Wednesday in the afternoon the spark on Kubernetes and the elastic story. Then the introduction to the Kubernetes working group patch. So we'll hear a bit about it, but there will be a more extensive session also in the maintainer track, in this case, on Thursday. And then we'll have a talk from an end user, which is from the Atlas experiment at CERN and how they use Kubernetes as their underlying key API to expose their compute resources and to use additional compute resources. So Lucas and Fernando also talk about this in the main event. So yeah, just as a last bit before we move on to the first talk, the main references that I think if you're interested in this area, the things to track, I would include the Kubernetes batch working group. It's recently formed, but it already has quite a lot of traction. There's actually weekly with two time zones meetings and it's been quite interesting. There's also a batch system initiative proposal that was sent to the CNCF, which has similar goals, but not totally overlapping. And this is something that is being kicked off slowly, but we hope to get it going as well. And then finally, I would pitch here the research user group that actually Bob is here. Yeah, Bob, we created it like, this was launched like after Barcelona 2019. It's kind of the precursor to all these activities and it's going and yeah, feel free to join. It's also bi-weekly meetings. And we cover not only batch, but things that are definitely of interest to this community. So that's it. Thank you everyone for joining. And I think we can go ahead with the first talk.
