2008-2011 RIP our first "cluster"

Our first cluster debuted on the June 2008 list @ number 61. It was our first tightly coupled system with 4096 cores DDR IB, 16TB of DRAM and used about 200KW of power. We lasted exactly 3 years on the challenge list with our 32TF Rmax, 38TF peak sustaining 85% efficiency machine:

June       2011     Poof! Gone!
------------------------------

We have grown significantly since and have ca. 13,000 cores on line, but it sure is sad to see how fast these systems conk out, with millions of $ being spent on them. It lasted just about as long as the warranty on the box did. 32TF is a bit pathetic these days, the K machine has just come in at slightly over 8,200TF, a whopping 256 times faster than our little box!

Rest in peace dearest little Dell box, you did great science!
