The original you found is much more informative that the one linked here. It goes into more detail and has more pictures, etc.

Great hack - but in terms of core density it's not exactly great.

The article talks of "What we needed was a compact and efficient design with maximal core density"

You can buy a Dell R410 1U 8 core (2 x 4-core Xeon) for about $1,400.

Whilst you are paying about 25% more, you'd get 24 cores into a fraction of the space. If you include the cost of power, the 'Ikea rack' is likely to cost a fair amount more over 3 years.

Original article is from 2008. Now you can get a 1U-twin Supermicro with 24 cores in 1U.

mrb• 16 years ago

The parent is correct. Many vendors make 24 cores in 1U nowadays. For example you can get an Asus barebone with two Opteron 6168 processors for $2290: $800 barebone (http://www.newegg.com/Product/Product.aspx?Item=N82E16816110...) plus two $745 processors (http://www.newegg.com/Product/Product.aspx?Item=N82E16819105...)

Actually you can get a 1U 48-core (4x12-core opteron) these days: http://www.supermicro.com/Aplus/system/1U/1042/AS-1042G-TF.c...

You may also wish to connect each drawer to the AC power ground on it's PSU

ars2• 16 years ago

Then you get grounding loops - not a good idea.

Connect all the drawers to a single ground, using only one direction (star, not ring).

oiuytgfrgh• 16 years ago

Ground loops probably aren't a big problem for a SMPSU - if you are putting power into a metal box you need to have a ground to the metal box.

Seems like a few different sizes of hole saws could be used to open the back of the drawers. They really hacked it up by cutting it the way they did.

Well, the $2550 total price for that platform is never the less shocking. And those are 2008's prices, today it shall come out even cheaper.

In other words, If I was thinking of giving my imaginary startup team (5) iPads as a bonus, I now have a better thing to do with the $2.5K, right?

Personal favorite Ikea use http://lackrack.org/

If you wanted to get that same amount of processing power using Amazon EC2, that $2550 would get you about 1250 hours (52 days).

Of course, you have to pay for your energy, build it, and maintain it.

The Blender guys also used such an approach...

Should put some sort of mesh\screen on the front label airports. Otherwise your cabinet is vacuum cleaner for dust.

And you get a free space heater!

It bothers me slightly that for the price of my 17" MacBook Pro I could have bought a 24 node cluster... At some level it just seems like one portable processor ought to be 1/24th or 1/12th (factoring in extra for the mobility) the price.

6 node cluster - 4 cores each for 24 cores.
