Capitalisation of usernames on the Wiki

[Tony Travis]

Hi,

I've just signed up on the Hackerdeen/57north Wiki as "ajtravis", but
MediaWiki capitalised the first letter of my username [Grr...].

I think Drupal is a lot better than MediaWiki :-)

Anyone interested in building a Beowulf in the Hacklab?

Tony.

Looked at building a HA cluster ages ago for a work project but had no time to research it. Would be keen to shadow this.

Cheers,

Ed

Hi, Ed.

I'm thinking more HPC than HA but I've got some kit I can donate if
anyone is seriously interested (Not VM-capable Opteron 200 systems).

In particular, I'd like to revive the "kerrighed" project:

http://kerrighed.org

Someone has started doing this already using Ubuntu 12.04 LTS as the OS.
I tried under Ubuntu 10.04 LTS, but couldn't get a stable system:

http://ubuntuforums.org/showthread.php?t=1030849

I've got 12@Dual Opteron 200 systems in 2U Rackable Systems cases plus a
few spares in my garage that I'm willing to donate to the Hacklab.

I can't afford the electricity to run them (~150W each when idle).

Bye,

Tony.

I have previously (and somewhat successfully) built a kerrighed cluster
on Debian 6. It would be good to get one working completely.
(Checkpoints failed miserably on the one I built).

We wouldn't be able to run them full time, but we would likely be
interested as soon as someone can find us a 48U rack (we have a 24U
currently and there wouldn't be enough space).

Hi, Iain.

Got Kerrighed 2 working fine, but crashed and burned with Kerrighed 3...

Ha! just put them on industrial shelving (see the photo of my garage).

The 2U servers I'm willing to donate are on the shelves at the end of my
garage: We don't need no steenking (expensive) 19" racks!

Anyway, I thought this was supposed to be a Hacklab... :-)

I've also got some Cisco Gbit switches to donate with the 2U servers.

Let me know if you want them?

Tony.

Actually can't remember which version I was running. All I remember is
that I could launch processes and they would remote fork but some IPC
failed and checkpointing would kernel panic.

I think you over-estimate the amount of space we have! We may be able to
source a 42U rack from one of the members. I'll bring it up at the
meeting tonight.

Gigabit switches are definitely something we want. Cisco gigabit
switches are definitely something I want because I know how to configure
them (unlike the HP 10/100 we have).
