  • Worked
    1. Optimization on stampede: ​https://astrobear.pas.rochester.edu/trac/astrobear/blog/bliu04042013
    2. New strong scaling test on stampede (O3):http://www.pas.rochester.edu/~bliu/Scaling/strongScalingOnStampedeO3.png
    3. In summary:
      1. with level 3 optimization, stampede is about twice faster than kraken on less than 1000 cores, which is fair — 1 SUs on stampede = 2 SUs on kraken
      2. Kraken has better strong scaling up to 5000 cores. (The maximum for stampede normal queue is 4096 cores)
      3. Current usage: stampede (40% | 169,343 SUs left), kraken (99% | 1,134,191 SUs left)

  • Working on
    1. optimization and scaling on blue hive and blue streak
