Axiomatic validation of memory barriers and atomic instructions [LWN.net] edit / delete
More progress on model checking for memory models on modern processors. The tool described here covers ARM, Power and x86 memory models, and does efficient analysis of (smallish) chunks of code.

Energy-efficient bcrypt cracking (Passwords^13 - PasswordsCon Bergen 2013) edit / delete
Keys/second/watt for various architectures. The manycore ones do very well -- they aren't fast as such but they're very power-efficient for the performance they get.
