ABSTRACT
With the advent of ubiquitous multi-core architectures, a major
challenge is to simplify parallel programming. One way to tame
one of the main sources of programming complexity, namely syn-
chronization, is transactional memory (TM). However, we argue that
TM does not go far enough, since the programmer still needs non-
local reasoning to decide where to place transactions in the code.
A significant improvement to the art is Data-Centric Synchroniza-
tion (DCS), where the programmer uses local reasoning to assign
synchronization constraints to data. Based on these, the system au-
tomatically infers critical sections and inserts synchronization oper-
