RobuSTM: A Robust Software Transactional Memory

2010
For software transactional memory (STM) to be usable in large applications such as databases, it needs to be robust, i.e., live, efficient, tolerant of crashed and non-terminating transactions, and practical. In this paper, we study the question of whether one can implement a robust software transactional memory in an asynchronous system.

Software Transactional Memories: An Approach for Multicore Programming

The Journal of Supercomputing, 2009
The recent advance of multicore architectures and the deployment of multiprocessors as the mainstream computing platforms have given rise to a new concurrent programming impetus. Software transactional memories (STM) are one of the most promising approaches to take up this challenge.

Scheduling Transactions in Replicated Distributed Software Transactional Memory

2013 13th IEEE/ACM International Symposium on Cluster, Cloud, and Grid Computing, 2013
Distributed software transactional memory (DTM) is an emerging, alternative concurrency control model for distributed systems that promises to alleviate the difficulties of lock-based distributed synchronization. Object replication can improve concurrency and achieve fault-tolerance in DTM, but may incur high communication overhead (in metric-space ...

Software Transactional Memory for GPU Architectures

Proceedings of Annual IEEE/ACM International Symposium on Code Generation and Optimization, 2014
Modern GPUs have shown promising results in accelerating computation intensive and numerical workloads with limited dynamic data sharing. However, many real-world applications manifest ample amount of data sharing among concurrently executing threads.

Multithreaded software transactional memory and OpenMP

Proceedings of the 2007 workshop on MEmory performance: DEaling with Applications, systems and architecture, 2007
Transactional Memory (TM) is a key future technology for emerging many-cores. On the other hand, OpenMP provides a vast established base for writing parallel programs, especially for scientific applications. Combining TM with OpenMP provides a rich, enhanced programming environment and an attractive solution to the many-core software productivity ...

Investigating software Transactional Memory on clusters

2008 IEEE International Symposium on Parallel and Distributed Processing, 2008
Traditional parallel programming models achieve synchronization with error-prone and complex-to-debug constructs such as locks and barriers. Transactional Memory (TM) is a promising new parallel programming abstraction that replaces conventional locks with critical sections expressed as transactions. Most TM research has focused on single address space

Architectural Support for Software Transactional Memory

2006 39th Annual IEEE/ACM International Symposium on Microarchitecture (MICRO'06), 2006
Transactional memory provides a concurrency control mechanism that avoids many of the pitfalls of lock-based synchronization. Researchers have proposed several different implementations of transactional memory, broadly classified into software transactional memory (STM) and hardware transactional memory (HTM).

D2STM: Dependable Distributed Software Transactional Memory

2009 15th IEEE Pacific Rim International Symposium on Dependable Computing, 2009
At current date the problem of how to build distributed and replicated Software Transactional Memory (STM) to enhance both dependability and performance is still largely unexplored. This paper fills this gap by presenting D2STM, a replicated STM whose consistency is ensured in a transparent manner, even in the presence of failures.

Enable Concurrent Byzantine Fault Tolerance Computing with Software Transactional Memory

International Conference on Advanced Software Engineering and Its Applications, 2015
Byzantine fault tolerance typically is achieved via state-machine replication, which requires the execution of all requests at the server replicas sequentially in a total order. This could severely limit the system throughput.

Practical Parallel Nesting for Software Transactional Memory

2013
Transactional Memory TM provides a strong abstraction to tackle the challenge of synchronizing concurrent tasks that access shared state. Yet, most TMs do not allow a single transaction to contain parallel code. We propose an efficient parallel nesting algorithm to explore existing latent parallelism within a transaction.
