Comment (by hinder):


 Note that the functionality of SystemTopology used to be present in hwloc,
 and Carpet used to activate hwloc automatically.  In your ET_2014_11 runs,
 can you check to see if hwloc is automatically activated?  This would
 explain what you observed: the old runs used hwloc, and the new runs
 didn't.  Activating SystemTopology restores the old behaviour.

 What was the ratio of speeds between the two runs?
