Runtime-Assisted Global Cache Management for Task-based Parallel Programs
Artikel i vetenskaplig tidskrift, 2017

Dead blocks are handled inefficiently in multi-level cache hierarchies because the decision as to whether a block is dead has to be taken locally at each cache level. This paper introduces runtime-assisted global cache management to quickly deem blocks dead across cache levels in the context of task-based parallel programs. The scheme is based on a cooperative hardware/software approach that leverages static and dynamic information about future data region reuse(s) available to runtime systems for task-based parallel programming models. We show that our proposed runtime-assisted global cache management approach outperforms previously proposed local dead-block management schemes for task-based parallel programs.
