Yes.  Life does get in the way sometimes.

It was definitely time to change the water. Here is a picture of the inside of the CPU water block.

nice rig man

[Buntz]

Thanks. I still have to get a silver killcoil and some more black hose so I can mount the radiator on the back of the box, then I will be done.

[mudmanc4]

Stays nice and cool I see as well.

[Buntz]

The temperatures are lower than normal. The radiator is sitting in the window pulling air in from outside. The temperature outside is 43F. I am cheating a little bit.  
Folding temperature can get as high as 65C [ around 148F ] on a hot day @ near 100% CPU usage.

[mudmanc4]

Does it help to run two radiators ?

[Buntz]

Not really. From what I read the best you can do is around 10 degrees over ambient temperature with water cooling. To get it lower than ambient takes some extreme measure. [Chilled water,Peltiers,Dry Ice,Liquid Nitrogen ] Chilled water and Peltier can be use on a daily bases,other two I don't think so. . Chilled water is a lot of work to set up and Peltier need a lot of power.

Have they come far enough with the Peltier that it doesn't drip condensation on and around the CPU ?  I use one sometime in the late 90's and what a mess that was.

[Buntz]

Did some reading on Peltier, I never use one. Yes they still have a condensation problem. You have to make sure you have proper insulation around the CPU. I guess that and the power usage you need to run one is why nobody use them much nowadays.

[mudmanc4]

Yea there was a felt pad or something then , i don't know what they have now for it. But the pad got soaked then dripped lol Really an interesting technology, if someone would put some time into it for this application it might do wonders.

For the month of April 2012 I was given access to the HP cloud free private beta.  The two primary services that will be offered at the public release are data storage and computing power for an hourly fee.  Now I heard rumors of people folding on the HP cloud and I was very interested.  So after a few days of waiting for a response from HP I found a "you've been accepted" message in my mailbox.    My first Linux server took 5 hours to setup.  Essentially I had to learn the tools before using the tools. With practice my 5th server only took 10 minutes to get running.  It was my goal to learn, find problems, fix problems, then report my results here so you all can also run servers on the HP cloud.  Well... as was said before, time flys.  When I was comfortable that my servers were stable and I could post here to share the word of temporary free computer power, it was no longer free.  The open beta starts May 10th 2012 at half price for all services.  Here is what I was running:

20 Servers of the following: Dual core, 2GB ram, 60GB hd, with various Linux distributions.  Price in free beta: $0.00
If I continued
20x: Dual core, 2GB ram, 60GB hd.  Cost in half price open beta: $0.04 per server = $19.20 / day  

The "HP Cloud Object Storage" is going to start at $0.06 per GB per month during the half price beta.

In summary
I learned a lot about the Linux command line, SSH, and now feel comfortable in the terminal window.  Science was benefited with over 500 folding at home projects completed on twenty dual cores in one months time.  I had fun and I hope you enjoy the following screen shots.

I was in the folding stats page yesterday , and noticed you were screaming ! Now i know why.

Thanks for the info as well , I cannot believe the cost, this is something I'll be delving into in the very near future , thank you.

Can anyone remember that charlie brown sound when lucy plucked the ball just as he kicked ?

ARRRHHGGGGGG   !!!!

Looks as if Iv'e hit that wonderful wall of linux not sending WU's .  I set up centos box thats used for me digging deeper into virtual technology but for the last couple weeks , yea well , no returns , just folding it's bum off. And to boot , looks as if the boy has once again forgotten to please return the PS3 to life with playstation so that the flippin thing can at the least be somewhat useful around here aside from mind mush.

[Blako]

Is it a problem with the linux virtual machine that is getting work but not returning the results?
Or
Is it a problem with the folding client itself?

Does the FAHlog.txt tell you that the jobs are failing to finish or that when they do finish, do they fail to upload?

Using your PS3 for something other then mind mush, lol I like it

[mudmanc4]

Yes , that machine (PS3 ) is mind mush , I think of it here and again , I actually took it out and dusted it

The WU's are completing, it grabs a new , and starts up , finishes and complains about can't reach destination. Even manually sending fails due to the same.

It's not in a VM , it's installed in a user on DOM0

Funky thing is I can ping the IP from terminal with 200 but the results fail to send. I read up last week and found there is / was a bug, but as always , sidetracked.

I shut it down in lue of this , and i use that machine for local DNS, just fire up that drive once a week or so to refresh the forwarder. Lazy I know , but it's the only 64 bit machine around here other than the mac , so everything else highly restricts what I can do along those lines. I am working on a virtual solution, maybe run w2k server ( which right now handles DNS and active directory ) , then again I'de still be losing a lot because things change around here so much.

One of these days I'll just stop playing and do emails, and test my overpriced connection, although at that time i won't give a care lol
