Multi-PFLOPS supercomputer roadmap

Print Friendly, PDF & Email

A post at Next Big Future got me to thinking about the shape of the known roadmap for the multi-PFLOPS (and larger) machines. I think it would be a fun insideHPC reader project to collectively document all of the extreme scale machines that are on the horizon right now.

I’m specifically not including SETI@home kinds of clusters here; a super has to be a collection of computing resources intended to be used (at least in substantial part) on a single task or relatively small number of tasks (relative to the number of cores in the machine) in order to be considered. So a supercomputer commissioned to run many multi-thousand core weather simulations (for example) would count, but Google’s datacenter doesn’t count. Likewise, botnets don’t count either. Also, to be listed, the machine has to have a planned peak performance greater than 1.999 PFLOPS, and has to be further along that “wouldn’t it be cool if we could build this machine.”

I’ll get things started; post changes or additions in the comments and I’ll update the list.

  1. ORNL, 2 PFLOPS (Jaguar), Cray (Opteron/Magny-Cours), 2009
  2. RIKEN, 10 PFLOPS supercomputer, Fujitsu (Sparc64 VIIIfx), 2010
  3. NCSA, 10 PFLOPS (Blue Waters), IBM (POWER), 2010
  4. NASA, 10 PFLOPS (Pleiades), SGI (Altix ICE/Xeon), 2010
  5. DOE NNSA, 20 PFLOPS (Sequoia), IBM (Blue Gene), 2011

    Can anyone from IBM or LANL comment on coming upgrades to RoadRunner?

  2. There are no hardware upgrades to Roadrunner. It is what it is.
