The wiring is the more interesting news actually.
Still running 23 TFlops but you can hardly call it a supercomputer by todays standards. The one Engadget compares it to, Germany's Jugene runs a whopping 1 PetaFlop and ranks No.5 on the supercomputer list. I guess that is where architects have to look. Btw, the wiring is much better too.

I wouldnt give those certs too much credit, many of the people in the US that have them are nothing more than certified test-takers.

No! Never cable ties. They can pinch the network cable and damage the little wires inside. Velcro only!

Also, these guys need to look into Middle Atlantic or Lowell Racks and some wire trays.

I'd go nuts on someone if that was my job and I walked in to see that mess of wires everywhere.]]>Jul 13th 2010 12:09PMhttp://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/http://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/Jul 13th 2010 11:46AMhttp://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/http://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/Jul 13th 2010 11:46AMhttp://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/http://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/Zip Ties.]]>Jul 13th 2010 11:49AMhttp://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/http://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/Jul 13th 2010 11:50AMhttp://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/http://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/Jul 13th 2010 11:50AMhttp://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/http://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/Jul 13th 2010 11:50AMhttp://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/http://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/Jul 13th 2010 11:52AMhttp://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/http://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/Jul 13th 2010 12:05PMhttp://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/http://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/Jul 13th 2010 3:42PMhttp://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/http://www.engadget.com/2010/07/13/tokyo-universitys-grape-dr-supercomputer-is-a-tangled-green-pow/

they should get the motherboards in a casing, no screens no mouse, nothing extra that is not necessary for the processing.
remove the network cards, and plug in a single multi-RJ45 card
then one remote console, to connect to all of them.
a KVM switch if you need to connect physically (remote control on intel is not as good as SUN's, no console or ALOM)

get the cables properly done, so they do not interfere with heat exhange.
close the cabinets, and add inverted/oppesed bottom and top fans, thus reducing the need for the fans on each machine to draw power.
in each box, remove the power, and use a centralised one. to gain in efficiency.

all cheap solution, this is a great feat, but not optimized

As others have mentioned this is barely a supercomputer, it has in fact fallen off the top500 list, but it is still powerful, and more important powerfully efficient, hence our addition of a little list to the site.
