Hardware transactional memory (HTM) is an attractive research topic in recent years. It has great potential to simplify parallel programming on the soon-to-be-ubiquitous multi-core systems. In this paper, a HTM design is proposed, and overall performance is evaluated. This HTM design distinguishes itself from others by its best effort philosophy. The hardware makes best effort to complete each transaction and software handles those transactions that cannot be completed by hardware. This design seeks a balance between application performance and hardware implementation complexity, and tries to answer the question: what should be done by hardware and what should be done by software. The overall performance of benchmarks is also evaluated by simulation

Synchronizing Resources (SR) is a language for writing distributed programs which supports many forms of interprocess communication to obtain high expressiveness. The design of SR is evaluated from the perspective of parallel programming. Several programs for parallel applications implemented in SR are studied, and some observations are made about the expressiveness and ease of use of SR. The results indicate that nearly all facilities provided by SR are useful for parallel programming. The language lacks message passing through mailboxes, message forwarding, and globally shared variables. SR is also fairly simple to understand. A strong point in the design is the orthogonality of the message sending and receiving constructs. Some points of criticism concern the multicast mechanism and the type-insecurity of the language.< >

The goal of the paper is to describe run time efficiency of distributed computing environments. Six tools: PVM, P4, ANSA, SR, Strand, and Linda were chosen and investigated because they represent different approaches to distributed programming systems construction. The experimental results of communication tests and processor farm model efficiency are presented and discussed.< >

This paper presents P-RIO, a parallel programming environment that supports an object based software configuration methodology. It promotes a clear separation of the individual sequential computation components from the interconnection structure used for the interaction between these components. This makes the data and control interactions explicit, simplifying program visualization and understanding. P-RIO includes a graphical tool that helps to configure, monitor and debug parallel programs.
