Exploiting Spatial Store Locality Through Permission Caching in Software DSMs
[chapter]
2004
Lecture Notes in Computer Science
Fine-grained software-based distributed shared memory (SW-DSM) systems typically maintain coherence with in-line checking code at load and store operations to shared memory. The instrumentation overhead of this added checking code can be severe. This paper (1) shows that most of the instrumentation overhead in the fine-grained SW-DSM system DSZOOM is store-related, (2) introduces a new write permission cache (WPC) technique that exploits spatial store locality and batches coherence actions at
