CSSTs are a novel data structure optimized for maintaining partial orders efficiently in dynamic analyses of concurrent executions.
Tiivistelmä
The content introduces Collective Sparse Segment Trees (CSSTs) as a data structure for maintaining partial orders in dynamic analyses of concurrent programs. It discusses the challenges faced in dynamic reachability analysis and presents the key concepts behind CSSTs. The structure of CSSTs, including minima indexing and sparse representation, is explained in detail. The content also provides examples and algorithms for updating, querying, and maintaining CSSTs.
Tilastot
Vector Clocks are slow for non-streaming analyses, costing O(n) time for each new ordering.
CSSTs allow for inserting, deleting, and querying orderings in O(log n) time.
CSSTs are shown to be efficient in handling various dynamic analyses in the literature.
Lainaukset
"CSSTs are the best data structure currently to handle a range of dynamic analyses from existing literature."
"CSSTs exploit the fact that the width of the partial order is much smaller than the size of its domain."
