Nested Parallelism in Transactional Memory Kunal Agrawal Jeremy T. Fineman Jim Sukha
... Since a worker may signal an abort of a transaction running on a (possibly different) worker whose descendants have not yet completed, the XCilk protocol for a transaction abort is more involved than for a commit. Suppose worker i wishes to abort an active transaction X running on a different worker ...

Three Problems about Dynamic Convex Hulls
... Next, we turn to another related fundamental problem: dynamic halfplane range reporting. The goal here is to maintain a set S of n points in the plane under insertions and deletions so that we can efficiently report all points inside a query halfplane. We let k denote the number of reported points, ...
