    —We present the skip vector, a novel highperformance concurrent data structure based on the skip list. The key innovation in the skip vector is to flatten the index and data layers of the skip list into vectors. This increases spatial locality, reduces synchronization overhead, and avoids much of the costly pointer chasing that skip lists incur. We evaluate a skip vector implementation in C++. Our implementation coordinates interactions among threads by utilizing optimistic traversal with sequence locks. To ensure memory safety, it employs hazard pointers; this leads to tight bounds on wasted space, but due to the skip vector design, does not lead to high overhead. Performance of the skip vector for small data set sizes is higher than for a comparable skip list, and as the amount of data increases, the benefits of the skip vector over a skip list increase.
