Top 500 Bof Live Blog. Mine is Bigger.

I decided to copy Gregg and do a live blog during the Top 500 BoF. This is the 32nd Top 500 list, a list of the 500 fastest computers in the world (that choose to run and submit Linpack benchmark numbers. there are many computers who's existence and specs are not publicly known). This info is all available on the Top 500 website, so nothing new is being unveiled here. If a fist fight breaks out I'll let you all know though.

#1

A slightly enhanced Roadrunner system (IBM BladeSystem based), which broke the petaflop barrier last June, held on to its top spot on the list with a 1.105 petaflop Linpack bechmark when Jaguar posted a "mere" 1.058 petaflop score.

update: 5 new or significantly upgraded systems in the top 10

#2 Jaguar at Oak Ridge National Laboratory, a Cray Xt5 system, over 150,000 cores

#3 NASA/Ames Research Center, SGI system, over 51,000 cores

#4 DOE/NNSA/LLNL Blue Gene L

#5 Argonne National Laboratory, IBM Blue Gene/P

#6 TACC Ranger (Sun, over 62,000 AMD Opteron Cores)

#7 NERSC/LBNL Franklin Cray Xt4

#8 Oak Ridge Jaguar Cray Xt4

#9 NASA/Sandia Cray Red Storm

#10 Shanghai Supercomputer Center, Dawning 5000A (Chinese company) First top 10 Windows cluster


Update

awards being given out

"Mine is bigger" T-shirt for Roadrunner


update:

The top 3 got certificates and t-Shirts with double meaning

Also an award for the fastest non-US supercomputer, the Microsoft powered Dawson at Shanghai Supercomputer Center.

update:

Award for fastest in Europe went to an IBM Blue Gene/P at Juelich in Germany.

update:
Purdue won the student challenge where they have to build a cluster from scratch and run linpack in a few days. They got over 700 Gflops. MIT came in 10th with less than 17 GFlops.
Turns out Purdue was using a SiCortex system.

update:
In June 300 systems fell off the list. This time 267 more systems fell off the list!

These are usually systems near the bottom of the list. Systems at the top generally stay near the top, until the institution needs the space to build something even faster.


update:
single core processors almost gone from list. quad core is taking over popularity from dual core. a small number of systems use cell processors with 9 cores.

update:
processors/performance Xeon E54xx(harpertown) #1 at 25%, Opteron Quad Core processors account for 19% of the performance on the top 500.

update:
HP delivered 42% of the systems, IBM 37%, Cray, Dell, and SGI provide a large amount of the power because they have a small number of very powerful systems. IBM still #1 by total performance on top 500

update:
U.S. still #1 consumer, has gone up.
Internationally Japan's market is going down in Asia, China has grown to #2, India to #3. South Korea shrinking.


U.K. #1 in Europe, Germany still #2 (they made big gains last year, fell further behind U.K. this year)
