If you get the clusterKnoppix LiveCD, there is at least one prime calculating client on the disk IIRC. That is supposed to be for testing the cluster. You boot one unit to the LiveCD or to it loaded on a HDD to be the master node, and the other units are set to bootp or PXE and they connect up to the master node on boot. Obviously, there are many ways to make this work and clusterKnoppix is not the only answer. Check out www.grid.org . Apparently some of the distributed.net team and a few SETI@home guys got jobs there at United Devices www.uniteddevices.com, who also does grid.org as a non-profit project. -----Original Message----- From: kclug-bounces(a)kclug.org [mailto:kclug-bounces@kclug.org] On Behalf Of James Sissel Sent: Thursday, November 17, 2005 12:50 PM To: Kclug(a)kclug.org Subject: RE: Somewhat OT: Top 500 list I love those projects and I'm involved in 4 of them.

Suggestions for interview questions
by Garrett Goebel 17 Nov '05

17 Nov '05

What type of networking questions would you suggest to weed out interview candidates during a 15 minute phone conversation? The emphasis would not be on any particular platform, but rather to discover if the candidate had a general understanding of tcpip networking, hardware, infrastructure, security, nat, firewalls, vpns, ipsec, ssl, dns, hubs, switches, routers, etc. Example: Q: Can you name a protocol responsible for dynamic IP address assignment? A: BOOTP or DHCP -- Garrett Goebel IS Development Specialist ScriptPro Direct: 913.403.5261 5828 Reeds Road Main: 913.384.1008 Mission, KS 66202 Fax: 913.384.2180 www.scriptpro.com <www.scriptpro.com> garrett at scriptpro dot com

C7 is suposed to be much faster and intended for laptops. If the correct board layout was made they could be extreemly eficent for clustering.. L.J had a article about a 16 node cluster in a tool box. they have made several. one used p3 mini-itx but needed a huge power supply. the pc104 units are near 100 the via's are 140 ish+ so it culd be done for relitivly inexpensivly right now.

Somewhat OT: Top 500 list
by Jack 16 Nov '05

There has been a change to the reports of the top 500 supercomputer list. They now indicate which OSes are run on the systems in the top 500. A ***whopping*** 78.2% (or 391) of all the top 500 supercomputers run a linux flavor or Linux compined with something else. Not sure what that is an indication of. A mixed Linux + ? OS? What's up with that? Oh yeah, 4 BSDs and 5 Macs. One of those MACs is *homegrown* and made the top 15, homegrown being made by the company, which looks like it may do some hush-hush work for the DOD.

Cable companies unbundling? Unbundling what? You can just get cable modem now, but they charge you more for that then for the basic cable with the cable modem, because they have to install the filters to block cable. I just had to go through rigamaroar with them as I did basic with modem, and didn't hook up the tv. They wanted to say I didn't have the tv and increase my bill by $30 a month, I proved I had tv and offered to call the state, and they said "oops". > _______________________________________________ > Kclug mailing list > Kclug(a)kclug.org > http://kclug.org/mailman/listinfo/kclug
