Constant RMR solutions to reader writer synchronization
We study Reader-Writer Exclusion [1], a well-known variant of the Mutual Exclusion problem [2] where processes are divided into two classes–readers and writers–and multiple re...

Explicit Exclusive Set Systems with Applications to Broadcast Encryption
A family of subsets C of [n] def = {1, . . . , n} is (r, t)exclusive if for every S ⊂ [n] of size at least n − r, there exist S1, . . . , St ∈ C with S = S1∪S2∪· · · ...

Time and Space Lower Bounds for Implementations Using k-CAS
This paper presents lower bounds on the time- and space-complexity of implementations that use the k compare-and-swap (k-CAS) synchronization primitives. We prove that the use of ...

Orthogonal range reporting: query lower bounds, optimal structures in 3-d, and higher-dimensional improvements
Orthogonal range reporting is the problem of storing a set of n points in d-dimensional space, such that the k points in an axis-orthogonal query box can be reported efficiently. ...

On the inherent weakness of conditional primitives
Some well-known primitive operations, such as compare-and-swap, can be used, together with read and write, to implement any object in a wait-free manner. However, this paper shows ...
