For the second straight year, IBM has dominated the HPC Challenge (HPCC) competition. The DOE/NNSA/LLNL team, using IBM's Blue Gene/L system, once again swept all four Class 1 benchmark awards. The four Class 2 productivity awards were split between MIT, IBM, The MathWorks and the Russian People Friendship University.

Class 1

The Class 1 HPCC benchmarks -- HPL, RandomAccess, FFT and STREAM-system -- are focused on raw performance. The first place winner of each benchmark was awarded a $500 prize. The complete results of the Class 1 awards are as follows:

G-HPL           Achieved      System         Affiliation      Submitter
-------------   -----------   ------------   --------------   -------------
1st place       259 Tflop/s   IBM BG/L       DOE/NNSA/LLNL    Tom Spelce
1st runner up   67 Tflop/s    IBM BG/L       BM T.J. Watson   John Gunnels
2nd runner up   57 Tflop/s    IBM p5-575     LLNL             Charles Grassl
                                
G-RandomAccess  Achieved      System         Affiliation      Submitter
--------------  -----------   ------------   --------------   -------------
1st place       35 GUPS       IBM BG/L       DOE/NNSA/LLNL    Tom Spelce
1st runner up   17 GUPS       IBM BG/L       IBM T.J. Watson  John Gunnels
2nd runner up   10 GUPS       Cray XT3 Dual  ORNL             Jeff Larkin

-------------   -----------   ------------   --------------   -------------
1st place       2311 Gflop/s  IBM BG/L       DOE/NNSA/LLNL    Tom Spelce
1st runner up   1122 Gflop/s  Cray XT3 Dual  ORNL             Jeff Larkin
2nd runner up   1118 Gflop/s  Cray XT3       SNL              Courtenay Vaughan

Triad (system)
-------------   -----------   ------------   --------------   -------------
1st place       160 TB/s      IBM BG/L       DOE/NNSA/LLNL    Tom Spelce
1st runner up   55 TB/s       IBM p5-575     LLNL             Charles Grassl
2nd runner up   43 TB/s       Cray XT3       SNL              Courtenay Vaughan

Class 2

The Class 2 awards focused on productivity (defined as 50/50 mixture of performance and elegance) and introduced subjectivity into the judging process but also to the submitters' criteria of what is appropriate for the contest. As a result, a wide range of solutions were submitted, spanning various programming languages (interpreted and compiled) and paradigms (with explicit and implicit parallelism).

The winner of the first three categories were each awarded a $500 prize. The complete results of the Class 2 awards are as follows:

1. Best overall productivity

Recipient: Bradley Kuszmaul; Affiliation: MIT CSAIL; Language: Cilk

2. Best productivity in performance

NASA Looks to Move Science Apps Into the Cloud

It seems only natural that the US space agency would be casting its eyes toward the clouds. Sure enough, NASA is now looking to cloud computing to optimize the operation of the agency's IT infrastructure for some of its science codes. Like many commercial businesses and government organizations, NASA is being asked to do more computing with fewer datacenter resources.
