David,
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?
