Your team seam to me a bit quiet last time…. Hope it is still alive
(b.t.w. I am joined since January 3th ’08 due reading this blog posted on Planet Ubuntu. http://stats.distributed.net/participant/psummary.php?project_id=8&id=469195)

LoCo Folding…. At Home…

After recently reading Aaron Toponce’s mention of contributing to distributed.net, I thought I’d throw down the gauntlet to other LoCo teams for something that we’re doing here in Florida.
For a little while we’ve had a Folding …

Yeah. That’s because they pull from Webkit, which keeps the useragent string as Safari on Mac. However, wouldn’t you rather identify as a Mac user than a Windows user?

I ran GIMPS for a while, but I wasn’t pleased with it’s stats and overall complexity setting up the client. It’s been a while since I’ve ran it though. Maybe things have changed.

<> Wow… Time to get my PC back up and running for use of that CUDA client! You joining the team NevDull?;)

As an aside, my Google Chrome on XP was mistakenly identified as Safari on OS X in the comment header thing.

The CUDA pre-release clients are even faster than the PS3.

On my 8800GT video card, I do 270+ MKeys/sec.

Yeah, my friend bought a PS3 specifically because it could run Linux, but we haven’t installed Ubuntu yet.. Hopefully we have a chance to do that soon.

Funny you should mention the power of Linux and the PS3 as yesterday I installed Ubuntu 8.10 on my 80GB PS3 to help pursuade the move back to d.net after a long absense. The key rates I am experiencing are truly epic and unrivaled! 165 Mkeys/sec which compared to my iMac 3.06Ghz Core 2 Duo (9 Mkeys/sec) makes mince meat of any machine out there! I may purchase a 2nd PS3 as a pure Linux box for serving music, movies, files and kickin’ more RC5-72 butt!

Yeah. I’ve already had this discussion with someone who interests himself in arguing for the sake of arguing. Brute forcing is nothing special, but the numbers coming out of it are. We could either speculate about the numbers with mathematics, or we walk-the-talk, and see them live. I prefer the latter.

Also, there’s not much additional electricity being used for myself. Neither of my CPUs support scalaing, so they were running at 100% to begin with. I pulled out a wattage meter to see the wattage difference between running the client and not, and it was a 2 watt difference. If I’m that worried about electricity and the whole “going green” thing, then I should unplug my alarm clock and use my cell phone instead, as it’s pulling more power. I have offset the extra use by replacing my CRT with an LCD, turning the brightness level way down, and adjusting power preferences as necessary when not in use. I think I’m pretty green.

I’ve thought about this, and did a wattage pull test on my two boxes. It was about a 2 watt difference. If it was anything significant, I’d be with you on that one, but it’s barely pulling the extra power. I offset it by changing the power preferences and brightness levels on my monitors.

Also, I’m looking into the OpenID problem. It’s the wp-openid plugin. I’ll probably just disable it until some bugs get fixed.

I’d rather not increase my CPU to run flat out on any machine. The additional noise, heat and electricity usage will only cost me more in cooling and fuel bills.

I really think the whole green/carbon-footprint drive has taken some of the wind out of the sails of distributed computing.

(by the way the openid part of this comment failed, and i was dropped to a nasty page that told me I must use the comment form to leave a comment, when i did, it failed again)

Well, using brute force to find the key doesn’t prove anything. It was an interesting experiment the first time, but now we know it can be done.

It would be cooler if they used all that processing power and evolution like code to make an RC5 key finder that did not need all that raw power.

As a side note: all that electricity could probably be used in better ways.
