Warewulf

Just finished my talk on +Warewulf  #NHC  for #MoabCon2014 .  I still need to wrap up the documentation updates and get the release out the door, but the talk went very well.  So grateful to +Adaptive Computing for allowing me to present again this year and always being so supportive of me and of the project.  I really appreciate all the opportunities they've given me year after year to engage with their customers and really build a solid community of users.  NHC wouldn't be anything close to what it is today without them, so THANK YOU ADAPTIVE!  (Special shoutouts to +Jill King +Ian Nate +Ken Nielson and +Rick McKay!)

And thanks to everyone who attended and to all the NHC users out there who have made it as successful as it is!

PS:  The talk was recorded, so as always, I'll post the video as soon as it's made available.  :-)

We have 2 new sub-projects under development now that are coming along nicely:

Node Health Check (NHC): The NHC is a framework designed to check a system to ensure that it meets a defined tolerance range. It can be run directly from the scheduler, CRON, or by hand.

Monitor: We are in the process of rewriting the Warewulf monitoring solution making use of persistent sockets, and bidirectional communication using JSON and in memory SQLite for data storage and retrieval by the aggregators. Accessing this pool of data can be easily done using a provided object oriented API in just several lines.

Anyone interested in testing or helping with these should let us know!

Thanks,

Greg

In the first article by Jeff Layton he described how to setup a base Warewulf cluster provisioning system. In this one Jeff continues on speaking about NFS, hybridization, user management, helpful tools and NTP.

Everywhere humans go, they create communities out of diverse, and sometimes hostile, populations. It is a great gift and a terrible responsibility...one that cannot be abandoned. -- Ambassador Delenn, "Babylon Five"

True to Warewulf's compartmentalized design, a number of subprojects come under the Warewulf project umbrella. Though most are modules of Warewulf itself, one that was recently added actually doesn't depend on the warewulf-common base at all! In fact, in the future there will be a Warewulf module which will rely on it.

The project is called the Warewulf Node Health Check, or simply "NHC" for short. NHC is an effort to build a framework, a tool, and a community around a common need: keeping track of whether or not compute nodes are ready to have jobs run on them.

Historically, most sites wound up writing their own one-off, home-grown solutions. While this approach is perfectly reasonable, understandable, and valid, it doesn't save anyone else the time and effort of having to recreate the same thing, nor does it leverage the prior work of others to the site's own benefit. So when faced with the same conundrum ourselves, we decided to take a different approach and write something that could be useful to a much broader range of HPC (and perhaps non-HPC as well) systems.

A lot of work has been done to fully document the script, the framework, and the pre-built tests it provides to make the learning curve as low as possible. Most recently, we've added tips on how to leverage built-in bash features to write your own custom checks optimally.

Give it a try, and let us know what you think! Feedback is welcome on the mailing list or in G+ comments. Enjoy!

We had a great time at Super Computing here in Seattle and I wanted to thank everybody that came to the booth and talks to support and learn more about Warewulf!

If you didn't have a chance to pick up the handout, please see the included link. See you next year in Salt Lake City, Utah!

Now I know where I found the discussion channel. It is the google groups area for WW. Found it by following the get help from WW site. I see now that discussions are created via mailing list submissions.
