In this paper, we evaluate the emerging Transactional Memory (TM) area by developing a set of Java transactional memory workloads and studying their performance under a Java Software Transactional Memory (STM) system and comparing them to their lock ...

While the chip multiprocessor (CMP) has quickly become the predominant processor architecture, its continuing success largely depends on the parallelizability of complex programs. In the early 1990s great successes were obtained to extract parallelism ...

This paper proposes an optimization method of data saving for application-level checkpointing based on the live-variable analysis method for MPI programs. We presents the implementation of a source-to-source precompiler (CAC) for automating ...

The need for high performance per watt has led to the development of multi-core systems such as the Intel Core 2 Duo processor and the Intel quad-core Kentsfield processor. Maximal exploitation of the hardware parallelism supported by such systems ...

We describe the ideas behind a method to use assertional reasoning to statically show that all sequentially consistent executions of a concurrent program are free from data races.

This paper first demonstrates the need for all-window profiling in a concurrent execution, then presents an approximate algorithm, and finally discusses related work.

Experience in profiling Lee's routing algorithm, a new complex TM application, showed that transactional applications may exhibit dynamic exploitable parallelism, i.e. the amount of useful parallelism available at any point in time varies during the ...

Today, multicore microprocessors are at the heart of systems ranging from laptops to supercomputers. The shift to multicore architectures has transformed the problem of improving program performance from a micro-architecture problem to a software ...

While there has been extensive work on the design of software transactional memory (STM) for cache coherent shared memory systems, there has been no work on the design of an STM system for very large scale platforms containing potentially thousands of ...

The current generation of software transactional memories has the advantage of being simple and efficient. Nevertheless, there are several parameters that affect the performance of a transactional memory, for example the locality of the application and ...

Substantial advances in STM performance in recent years have mostly focused on blocking systems. We describe our work integrating the most important techniques and optimizations emerging from the recent work on blocking STMs into several variants of a ...

We describe a methodology for transforming a large class of highly-concurrent linearizable objects into highly-concurrent transactional objects. As long as the linearizable implementation satisfies certain regularity properties (informally, that every ...

Transactional Memory (TM) is on its way to becoming the programming API of choice for writing correct, concurrent, and scalable programs. Hardware TM (HTM) implementations are expected to be significantly faster than pure software TM (STM); however, ...

This work presents a quantitative approach to analyze parallelization opportunities in programs with irregular memory access where potential data dependencies mask available parallelism. The model captures data and causal dependencies among critical ...

Transactional memory (TM) is perceived as an appealing alternative to critical sections for general purpose concurrent programming. Despite the large amount of recent work on TM implementations, however, very little effort has been devoted to precisely ...

This paper investigates adding transactions with nested parallelism and nested transactions to a dynamically multithreaded parallel programming language that generates only series-parallel programs. We describe XConflict, a data structure that ...

The ZeptoOS project is developing an open-source alternative to the proprietary software stacks available on contemporary massively parallel architectures. The aim is to enable computer science research on these architectures, enhance community ...
