Got our cluster on the BOINC medicine

Beansprout · 1 Feb 2006 at 21:59

I do lots of work with the World Wind Central community and recently we've done some ad-running and fundraising, and purchased 25 el-cheapo $70 1Ghz P3s to process imagery to load in to World Wind.

But...the cluster has idle cycles...soo....you can guess the next bit

Joined OcUK & loaded 'em up with BOINC Rosetta@Home earlier today, and:

Total credit 6.10
Recent average credit 38.36

Mmmm, old crappy hardware:

Should get the Rosetta@Home OcUK rank up a few places

Nice 25Ghz Central heating you have there..

great work in helping the cause!

I note the bare walls. Hope they're not somewhere vulnerable.

Also note the benefit of American power connectors. So much more space-saving than their UK equivalents (I happen to have a six-way adapter myself for when I go travelling over there). Just don't pull too hard - the plugs will fall out.

Hehe, Matt (the dude whose basement we're taking over) had some fun sorting out the electrics and heating...gotta say it's a novel way to install underfloor heating

And no, he didn't flip the breaker by being unable to count...honest

Be interesting to see how they do....we aim to build up to 100 machines over time

Yeah, right, like I'm going to believe that.

We had enough trouble with a dedicated machine room full of hardware tripping out the breakers. You need slow tripping breakers for machine rooms so they don't freak out from the surge current triggered by all that hardware turning on at the same time. Though I'm guessing in this case it was an overload trip, plain and simple.

Aye, it was an overload. Forgot to count in the other equipment (his PC setup) on the same circuit

And turning on at the same time :eek:

I will not take such insolence, Adam is running this op

dsh -r ssh -a 'hostname; sleep 10; reboot

Reboots are not the problem. It's power-on that causes the surge, so you're fine until the next powercut (or breaker trip). Adam may be clever, but I doubt even he (or his scripts) can manage telekinesis.

Could use an APC remote power switch of course, but that would be ever so slight overkill

Electrics are setup by an electrician brother dude, who if he is as insane as Matt should be reasonably safe

The major thing will be installing a cooling system....gotta get a cheap VESDA setup :eek:
