DynAMO: Improving Parallelism Through Dynamic Placement of Atomic Memory Operations

With increasing core counts in modern multi-core designs, the overhead of synchronization jeopardizes the scalability and efficiency of parallel applications. To mitigate these overheads, modern cache-coherent protocols offer support for Atomic Memory Operations (AMOs) that can be executed near-core (near) or remotely in the on-chip memory hierarchy (far).
