It’s come to my attention that some people have received viruses from an address claiming to be Gordon Heydon in the csamuel.org domain – this address does not exist (and never has) and the emails in question were forged by a virus on a Telstra subscribers PC.
Anyway, now that’s out of the way…. I’ve been a bit quiet here recently so just a couple of quick updates on things I’ve been playing with:
An Open Source Instant Messaging system. All specified in XML so it’s easily extensible (and programable) plus has the ability to use connectors to interface to legacy IM systems such as MSN and ICQ. This means you only need to sign into your Jabber server and your Jabber server can sign into MSN, etc, on your behalf and act as a proxy, and your contacts think you’re using the legacy system natively.
My Jabber ID is: email@example.com – NB: That is NOT an email address!
SPBS is a queueing system used in clusters to share out and jobs between the compute nodes. I’ve been doing a fair bit of debugging at work with the guys who are maintaining this and they’ve been doing sterling work. Respect guys!
The MAUI scheduler interfaces with SPBS (and OpenPBS) and does clever tricks to work out the most efficient way to execute jobs in the PBS queue(s) based on policies and, most importantly, what the user tells SPBS is the maximum amount of time their job will run for.
NPACI Rocks is a Linux distribution specifically for cluster computing. It’s based on RedHat 7.3 for the IA32 release (and there’s an IA64 version based on RedHat Enterprise Linux 2.1) and includes virtually everything you could want for running a cluster (apart from SPBS mentioned above, they still use the old OpenPBS at the moment).
Very impressed with it so far, especially the automated installation tools and the PXE network boot support for automatic installs. The only issue I’ve had with it has been its use of the autofs automounter, I much prefer permanent mounts and autofs also doesn’t work with our preferred way of partitioning up user areas so that we guarantee they fit on a single DLT.
…well for MandrakeClub members at least! Grabbed it via BitTorrent (I’m a club member) – my first (and probably only) use of a Peer2Peer application (and legitimate too!).
I’ve been playing around with the pre-releases already and I’m impressed, but I need a bit of time to burn the ISO’s onto CD’s and have a real play with the release versions..
…and that’s about it for now!
