A formal semantics of nested atomic sections with thread escape

摘要

The multi-core trend is widening the gap between programming languages and hardware. Taking parallelism into account in the programs is necessary to improve performance. Unfortunately, current mainstream programming languages fail to provide suitable abstractions to do so. The most common pattern relies on the use of mutexes to ensure mutual exclusion between concurrent accesses to a shared memory. However, this model is error-prone and scales poorly by lack of modularity. Recent research propos
