Transactional Memory (TM) is a synchronization model for parallel programming which provides optimistic concurrency control. Transactions can run in and are only serialized case of conflict. In this article we use hardware TM (HTM) to implement an speculative barrier (SB) replace the lock-based...

Leadership is the activity to influences others in order guide them towards a certain goal (Miftah Thoha, 2013; 121). A leader someone with capabilities and advantages so that they can guides work together for similar goal. Political leadership covers wide range of topics due how country are constituted by structures designed run it. Transactional occurs because default form social control betw...

Background and Scope Parallel programming in the multicore era is a challenging task, and novel approaches are needed to ease the development of parallel applications. Transactional memory has been proposed as an alternative to the traditional lock-based approach to express and manage concurrency. During the last few years we have seen an increasing interest in programming languages, run-time s...

Researchers have proposed transactional memory as a concurrency primitive to simplify the development of multithreaded programs. In this paper we present a new approach for supporting I/O operations in the context of transactional memory. Our approach provides isolation between the file operations of different transactions while allowing multiple transactions to concurrently perform I/O. To eas...

Transactional memory is a promising technique for enforcing disciplined access to shared data in a multiprocessor system. Transactional memory simplifies the implementation of a variety of concurrent data structures. In this paper, we study the benefits of a modest, real-time aware, hardware implementation of transactional memory that we call micro-transactions. In particular, we argue that har...

Transactional memory (TM) is a novel approach for handling concurrency issues. By experimenting on a prototype system implementing transactional memory in hardware, we aim at investigating if TM is of benefit for scientific and high-performance computing. The main goal of our work is to exploit the optimistic nature of transactional memory and increase performance by reducing the overhead from ...

Common goal of descriptive data mining techniques is presenting new information in concise, easily interpretable and understandable ways. Hierarchical clustering technique for example enables simple visualization of distances between analyzed objects or attributes. However, common distance measures used by existing data mining tools are usually not well suited for analyzing transactional data u...
