We introduce transactions into libraries of concurrent data structures;
such transactions can be used to ensure atomicity of sequences of data
structure operations. By focusing on transactional access to a
well-defined set of data structure operations, we strike a balance
between the ease-of-programming of transactions and the efficiency of
custom-tailored data structures. We exemplify this concept by designing
and implementing a library supporting transactions on any number of
maps, sets (implemented as skiplists), and queues. Our library offers
efficient and scalable transactions, which are an order of magnitude
faster than state-of-the-art transactional memory toolkits. Moreover,
our approach treats stand-alone data structure operations (like put and
enqueue) as first class citizens, and allows them to execute with
virtually no overhead, at the speed of the original data structure
library.

Joint work with Alexander Spiegelman and Guy Golan-Gueta, to appear in
PLDI 2016.
