This paper presents RReplay: a novel record & replay system for multi-threaded programs to solve their debugging problems caused by non-deterministic thread interleavings. The idea of RReplay is to only record the key non-deterministic behaviors that mostly affect performance. Different from existing approaches, RReplay requires that the programs be executed in a restricted environment so...
Atomicity violation, a common bug that obsesses multithreaded programs, has made the developing of multithreaded programs a daunting task. Atomicity is a basic correctness property of such programs. We propose strong atomicity, an efficient mechanism that helps programmers to write correct atom blocks with very little effort. We provide atom_start and atom_end for programmers to annotate an atom block...
Checkpoint-restart techniques are very important fault-tolerance approaches for these systems. As we know, the overhead of checkpoint will influence the system performance seriously. Incremental checkpoint is a well researched technique to reduce the overhead of checkpoint. However, huge memory footprints of parallel applications place severe limitations on scalability of conventional incremental...
Transactional memory has been proposed as an alternative to the traditional lock-based approach to express and manage concurrency in the multicore era. Among transactional memory techniques, software transactional memory (STM) is the most flexible and widely researched. However, researches show that STM suffers performance problem. In this pager, we present an overhead model for STM and our model...
