HA-OSCAR 1.0 Beta release - unleashing HA Beowulf
ImmO writes " The eXtreme Computing Research (XCR) group at Louisiana Tech University is pleased to announce the first public release of HA-OSCAR 1.0 beta. High Availability Open Source Cluster Application Resource (HA-OSCAR) is an open source project that aims toward non-stop services in the HPC environment through a combined power of High Availability and Performance Computing solutions. Our goal is to enhance a Beowulf cluster system for mission-critical applications and downtime-sensitive HPC infrastructures. To achieve high availability, component redundancy is adopted in HA-OSCAR cluster to eliminate single point of failures, especially at the head node. HA-OSCAR also incorporates a self-healing mechanism; failure detection & recovery, automatic failover and fail-back. The 1.0 beta release supports new high-availability capabilities for Linux Beowulf clusters based on OSCAR 3.0 It provides an installation wizard GUI and a web-based administration tool that allows a user to create and configure a multi-head Beowulf cluster. A default set of monitoring services are included to ensure that critical services, hardware components and important resources are always available at the control node. "
Just imagine a beowulf cluster of those! (fp)

Worth noting also, Linuxworld magazine has an article this month on HA-OSCAR which is pretty good!
Have a Happy.

I wonder how many posts will be constructive on this topic, and how many that will be that "imagine a..." joke.
:)
But all hail HA-OSCAR. Powercomputing to the people.

I recently aquired about 30 Opteron Boxes by a company who was throwing them out. I wanted to do some clustering work with them, but I was worried about how to do it. The features of this system looks like it can do it, espcially for my database system, which has over 10 billion rows worth of data that my company has aquired over the last 10 years. I will check it out!

Thanks for ruining it.

Never mind.
So on a multi-CPU sever if you started the same process synchronously on multiple CPU, how close in time would they finish assuming there is sufficient memory and disk drive controller to prevent severe competition?
I make my face look like this and concerned words come out.
A Beowulf cluster of Beowulf cluster jokes... :-)
they should put their web page on that cluster and see if it can handle a /.ing...if it does, then i would allow them to admit its high availability
...please no redneck hillbilly white trash jokes please
Just Imagine the beowolf cluster jokes now.

Weird, there was a story online, talking about a farmer not wanting to give his name to a police officer (wired-reference). I wanted to comment a already given comment and then: Boom, the story's gone. Part of the pay-preview-system? I still have the stuff on cache, so maybe the editors want to check their system for bugs... It is irritating...

This is just taking it a bit too far... I mean, if you dont want to give your name to a police officer when asked for it, you should be hiding in your basement with a tinfoil hat on.

The link in the story to OSCAR 3.0 should be to http://oscar.sourceforge.net The other site is just the parent organization's info page.
Is it because they have un-killable servers, or rather that is this not a hot enough topic here?

"Just imagine one of these!" doesn't have the same ring ...
Yes I fscking can imagine using this in a Beowulf cluster, so don't even ask.
Mozilla got in IP trouble with the name Phoenix, as AMI had some sort of browser called Phoenix.
Then there was a big snit over Firebird, because of the pre-existing database software. These things happen all the time. It's stupid, but it does happen.
This said, is this project gonna run into issues with AOL regarding the "OSCAR" in the name? (AOL's IM protocol is called OSCAR).
How different in technology implementation is the open source OSCAR vs. the grid computing technology? or any other form of cluster s/w out there?
It isn't surprising that beowulf clusters would want to incorporate mechanisms to deal with node failure, but I am curious if those who have worked on actual clusters could expand on the most common causes of failure. I was surprised to read in a previous slashdot post (sorry no URL) that even clusters of mini-ITX boards without hard drives (the most failure-prone component I would have thought) have frequent failures.

I actually go to Louisiana Tech. Chokchai Leangsuksun (Dr. Box), the director of the HA-Oscar program also teaches my Operating Systems class. He came into class today looking tired...he said he'd been working very hard on it.
I think it's about time LaTech got some recognition.

Mosix does this, but what about this? Or do you have to recompile and optimize for clustering?
In a 'regular' environment auto propagate would be more useful.

How does this compare to OpenSSI? OPenSSI is nice because of the single system image approach, that makes administration very simple. AFAIK, an OpenSSI cluster also supports PVM and MPI in addition to exec and run-time load balancing (a'la mosix).
OpenSSI has a lot of "HA-" support, including support for various clustered filesystems, failover of network interfaces across nodes, and failover of the first node (hopefully soon without needing shared SCSI storage but using something like drbd).
