Query: Branch-Avoiding Graph Algorithms   This paper quantifies the impact of branches and branch mispredictions on the
single-core performance for two classes of graph problems. Specifically, we
consider classical algorithms for computing connected components and
breadth-first search (BFS). We show that branch mispredictions are costly and
can reduce performance by as much as 30%-50%. This insight suggests that one
should seek graph algorithms and implementations that avoid branches.
  As a proof-of-concept, we devise such implementations for both the classic
top-down algorithm for BFS and the Shiloach-Vishkin algorithm for connected
components. We evaluate these implementations on current x86 and ARM-based
processors to show the efficacy of the approach. Our results suggest how both
compiler writers and architects might exploit this insight to improve graph
processing systems more broadly and create better systems for such problems.
