Safe privatization in transactional memory

Avoiding Publication and Privatization Problems on Software Transactional Memory

This paper presents a new approach to exclude problems arising from dynamically switching between protected concurrent and unprotected single-threaded use of shared data when using software transactional memory in OO languages such as Java. The approach is based on a simple but effective programming model separating transactions from non-transactional operation. It prevents the application prog...

Hybrid Transactional Memory to Accelerate Safe Lock-based Transactions

To reduce the overhead of Software Transactional Memory (STM) there are many recent proposals to build hybrid systems that use architectural support either to accelerate parts of a particular STM algorithm (Ha-TM), or to form a hybrid system allowing hardwaretransactions and software-transactions to inter-operate in the same address space (Hy-TM). In this paper we introduce a Hy-TM design based...

Can Software Transactional Memory Make Concurrent Programs Simple and Safe?

Parallel programs are key to exploiting the performance of modern computers, but traditional facilities for synchronizing threads of execution are notoriously difficult to use correctly, especially for problems with a non-trivial structure. Software transactional memory is a different approach to managing the complexity of interacting threads. By eliminating locking, many of the complexities of...

Transactional Memory

Shared memory parallel architectures present a single unified address space to each processor. Usually the memory is physically distributed across the system but each processor is able to access any part of it through a single address space. The system hardware is responsible for presenting this abstraction to each processor. Communication between processors is done implicitly through normal me...
