Developers and researchers design parallel systems and concurrent
algorithms using models---both formal and mental---that abstract away
details of the underlying hardware. In practice, however, these
hidden hardware/software interactions often have a dominating impact
on performance. In this talk, I will show how understanding the
interplay between hardware and software can lead to more efficient
program execution and better algorithms, which are achieved through
more precise models and architectural changes:
(1) I will show how understanding the implementation of the x86
processors' total store ordering (TSO) memory model enables designing
a fence-free work stealing algorithm, which was thought to be
impossible.
(2) I will describe how insights on the way software uses atomic
memory operations lead to a novel hardware architecture design, which
parallelizes the execution of certain atomic synchronization
instructions instead of serializing them.
