Who's the system administrator on the project?

Right under Eric's name it says "Project Administrator" Take a grain of salt and call me in the morning.

I run Einstein as well. They seemingly have a better group or configuration.

They have $$$$$$$$$$, Seti@home doesn't.

I worry SETI is just a part time job for some of your people.

No need to worry, it is a part time job! Not enough $$ for anyone to be full time.

A conference to discuss SETI and technology as well as whether the analysis path pursued is still viable or do we need a shift in overall approach to maximize the utility of you SETI volunteer corps.. Given a rudimentary analysis of Earth's radio frequency history (we go from Broadband Noise pulse generation to Digital Microwave inside of a 100 years) you realize other civilizations might only use RF for communications for a very short window in time. Even if the signals are floating around out there time coincidence is very unlikely and probability of intercept very low low indeed. Then propagation distance means any intercepted signals would be so far back in time that we'd be unlikely and unable to communicate back within any reasonable period to establish a comm channel.

Perhaps looking at advanced communication methods like lasers, or even neutrino emissions might be promising.. Don't know the answer only that our RF search has som many "depends on" that it's probability is very very unlikely.


Feel free to stop by http://www.gpuug.org/catalog and make a generous donation. We have a campaign going on right now to purchase two new servers for Upload / Download / BOINC / NTPCKR. You can also make a cash donation to S@H to support their general fund which helps keep the lights on. Both are tax deductible if you live in the US (and a few other countries.)

Matt,

I'm so glad to see that the new machines have made it safely to your doorstep! It's to bad they have to go unloved until you get things sorted out in other areas. As Marvin the Martian would say, "Oh drat these computers, they're so naughty and so complex. I could pinch them!"

One of those really has 9 DIMM slots per CPU? (As opposed to a binary multiple?)

Tripple channel perhaps?


Aparently I need to go back to remedial counting. The Intel system has 6 slots per CPU and can take up to 96GB. The Supermicro has 9 per and can take up to 288GB.

I was just doing some reading on the 5520 chipset and they are indeed triple channel, but they allow two DIMMS per channel with no decrease in performance.

Any special reason for the physical arrangement of the populated DIMMs?


It does look kind of odd, but the 5500/5600 series Xeon processors require a minimum of three DIMMs per CPU, so you can have four but not two. One machine has 9 slots per CPU with 96GB installed (6x16GB) and the other has 12 slots per CPU with 128GB installed (8x16GB.)

The Intel machine has an insane number of fans in it, and it's incredibly loud. I was staggered by the sound and how much air moved through it so I hope no one has a desk anywhere near it at the installation location. I should have taken a recording of it it's that crazy!

Hi folks,

Big things are afoot! I spent the morning today assembling all of the parts for the new Astropulse/NTPCKR and Download servers. Thank you to all the generous donors who made this purchase possible!

Check out the photos here!

The machines will be shipping out tomorrow and should arrive at the S@H offices in a few days. You can check their progress and tracking info on this page. Don't expect immediate changes to the project though; it will take some time for the S@H staff to install everything, get the software configured, do some stability testing and finally migrate everything over. Keep your eyes open for updates as things progress.

And finally, I would like to offer a special "Thank You" to Graham Middleton whose more-than-generous donations made the purchase of these machines possible in a far shorter time frame than we anticipated. These servers are dedicated to the memory of his parents - may they rest in peace!

I thinking about donating now with paypal, but the security certificate is wrong on the gpuug page. Could you check that out? Hostname and cert name is different.


Problem solved - the issue was mixed content due to the translate block, which has now been removed on the checkout page.

send me a screen shot of what you're seeing to webaster@gpuug.org


Oops, typing fail - webmaster@gpuug.org, though some would suggest I add a "d" at the end instead of an "m" in the middle.

Happy Holidays everyone!

1. Areca Dual core 6G SAS 2.0 full height 3 RAID card support 12 internal and 4 external ports, cables included mfg: ARC-1882IX-12 1. QTY: 1 2. COST: $1,028.50 3. TOTAL: $1,028.50


After much discussion with the S@H guys, they've opted for the 3ware 9750-4i4e SATA/SAS 6Gb/s PCIe RAID Adapter instead of the Areca listed here. If you're interested in donating hardware, please check http://www.gpuug.org/donatehardware/ for the most up-to-date list.

Hello, EPG! The security certificate is correct and issued to www.gpuug.org. I don't know what you're looking at, but they do indeed match. This is not an extended validation cert, so no owner info is listed. If you want, you can send me a screen shot of what you're seeing to webaster@gpuug.org.

Here's what I see:


Regardless, we don't collect your credit card info anyway, PayPal does, so you don't need to worry about about it. We're just securing your personal information and preparing for when we use Authorize.net somewhere in the near future. Please donate with confidence!
