The oldest computers on the November 2007 Top500 are 3 computers that have the whopping age of 5. Yes, five whole years old!

#30 (amazingly) The Earth Simulator at 35.8 Tflops
#91 (in the top 100 still) LANL ASCI Q at 13.88 Tflops
#331 NERSC/LBNL an IBM SP at 7.3 Tflops.

We had 5 four year olds and 10 three year olds that made the list. That’s it. So, if your system is over the age of three you have less than a 4% chance you’re still on the list.

The moral of the story? Brag fast, you’ve got a VERY limited shelf life.

It’s a sad commentary on the world of HPC when my computer gets thrown down the Top500 list like it’s a cliff.

Only a year old and my tennis court sized, 11k+ processor Cray won’t even make the top 20. It’s a travesty I tell you!

You all can go away. I’m taking my HECToR Toy and going home!!! I don’t wanna play no more! Pththththt!!!!

NCSA does not have a BG/P that is at Argonne. It is a DOE machine and is not in anyway connected to Blue Waters, which is an IBM HPCS machine and an NSF project.
