At the recent Supercomputing conference in Denver, I spoke with the University of Washington Boundless DAWG student supercomputing team.
(You can listen to the full interview at https://youtu.be/MxzH7k57VHs)
Rich: I'm here with the team from the University of Washington at the Student Cluster Competition, at SC19. I was wondering if you could tell me about your experience. Was this a positive experience overall?
Univ Washington: Yeah, it was a super positive experience. We got to travel. We got to meet all kinds of new people - industry professionals - and we got to go out of our comfort zone. None of us had any HPC experience at all except for Andrei, who's our senior - our leader on the team, our spiritual leader. So we learned a lot in this experience. And we struggled. But we came through it as a team. And we expect that to show in the results.
R: What were some of the struggles?
UW: Well, we came without a rack. And we learned that we could be disqualified if we did not have our cluster in the rack by Monday at 9:30. So our spiritual leader, Andrei, had to find a rack on Craig's List, or Facebook Marketplace, and then drive to Boulder to get the rack for $100. But everything turned out to be alright, and we have our rack, and we're not disqualified, yet. So far.
R: That's amazing.
R: For those of you who didn't have any HPC experience going into this, what convinced you to join a venture like this?
UW: First of all, supercomputers are pretty awesome. So I wanted to learn a lot more about it. Also this seems like a pretty cool competition experience. There's not that many competitions that take place for most of a week. And also there's not that many competitions that allow underclassmen to be involved in supercomputing, let alone on the world stage.
R: Who were your primary sponsors for this?
UW: The primary sponsor was AWS. And we had secondary sponsors Melanox, Intel, Invidia, who provided Tesla V100s. And Melanox provided Infiniband to connect our nodes together. Intel and AWS teamed up to give us money to cover the rest of the hardware.
R: Why did you choose CentOS for your base operating system?
UW: I think one of the primary reasons we ended up going with CentOS is, looking at last year, virtually every team used CentOS in the competition. We knew right away that there was a reason for that, and part of that reason was very likely due to stability, compatibility, and after figuring out what some of the applications were, we also found out that some of the applications were only guaranteed to work with CentOS. So apparently they tested on only CentOS. Might as well not make it harder on ourselves by trying to use something different.
R: Thank you all for your time. Good luck when the results come out.
On 2019-11-13 the CentOS Board of Directors held their first meeting following the release of CentOS Linux 8 and announcement of CentOS Stream.
As covered in this meeting, the CentOS Board are taking on an initiative to increase transparency of the working of the Board. This set of minutes for the community and wider public is the first instance of new, more transparent processes in action.
Topics covered in the meeting and via email are discussed below, and remain open on the Board’s rolling agenda for future conversation and actions:
The CentOS Atomic SIG has released an updated version of CentOS Atomic Host (7.1910), an operating system designed to run Linux containers, built from standard CentOS 7 RPMs, and tracking the component versions included in Red Hat Enterprise Linux Atomic Host.
CentOS Atomic Host includes these core component versions:
CentOS Atomic Host is available as a VirtualBox or libvirt-formatted Vagrant box, or as an installable ISO, or qcow2 image. For links to media, see the CentOS wiki.
If you’re running a previous version of CentOS Atomic Host, you can upgrade to the current image by running the following command:
The CentOS Atomic Host image follows the upstream Red Hat Enterprise Linux Atomic Host cadence. After sources are released, they’re rebuilt and included in new images. After the images are tested by the SIG and deemed ready, we announce them.
You’ll often find us in #atomic and/or #centos-devel if you have questions. You can also join the atomic-devel mailing list if you’d like to discuss the direction of Project Atomic, its components, or have other questions.
If you run into any problems with the images or components, feel free to ask on the centos-devel mailing list.
Have questions about using Atomic? See the atomic mailing list or find us in the #atomic channel on Freenode.
We are excited to announce the release of CentOS 8, and of the new RHEL upstream, CentOS Streams. Details can be found on the CentOS-Announce mailing list.
We are pleased to announce the general availability of CentOS Linux 7 (1908) for the x86_64 architecture. Effectively immediately, this is the current release for CentOS Linux 7 and is tagged as 1908, derived from Red Hat Enterprise Linux 7.7 Source Code.
Full details are on the centos-devel mailing list.
