XSWAP

  • Vaikunth continues work on cleanup of log data transformation scripts.  Looking to produce a few plots by the end of the sprint.
  • Vaikunth would like to run some tests to see if randomized input query sets (as currently generated by runqueries.py) produce statistically stable measurements.  If this is the case, we can leverage our existing tools for upcoming profiling experiments.  If not, we'll need some new tools that provide repeatable query sets.
  • Vaikunth will be updating and using IN2P3 nodes 124-149 for these experiments.
