Most systems that support speculative parallelization, like hardware transactional memory
(HTM), do not support nested parallelism. This sacrifices substantial parallelism and …

Recent work on transactional memory (TM) bears promise to exploit multicore capabilities.
TM extensions for thread-level speculative parallelism (TLS) have predominantly focused on …

Speculation with transactional memory systems helps pro-grammers and compilers produce
profitable thread-level parallel programs. Prior work shows that supporting transactions that …

" Is transactional memory useful?" is the question that cannot be answered until we provide
substantial applications that can evaluate its capabilities. While existing TM applications can …

Multicore designs have emerged as the mainstream design paradigm for the microprocessor
industry. Unfortunately, providing multiple cores does not directly translate into performance …

Multicore systems should support both speculative and non-speculative parallelism.
Speculative parallelism is easy to use and is crucial to scale many challenging applications …

Transactional memory (TM) is a speculative shared-memory synchronization mechanism
used to speed up concurrent programs. Most current TM implementations are software …

Thread-level speculation can speed up a single-thread application by splitting its execution
into multiple tasks and speculatively executing those tasks in multiple threads. Efficient …

BACKGROUND As multi-core chips become more popular, their support for multi-threaded
applications becomes more important. Hardware transactional memory is one such …

Speculation is a well-known means of increasing parallelism among concurrent methods
that are usually but not always independent. Traditional nonblocking data structures employ …
