Multi-core programming presents developers with a dramatic paradigm shift. Whereas sequential programming largely allowed the decoupling of source from underlying architecture, it is now impossible to develop new patterns and abstractions in isolation from issues of modern hardware utilization. Synchronization and coordination are now manifested at all levels of the software stack, and develope...

Article history: Available online xxxx a b s t r a c t Recently there is a trend to broaden the usage of lower-power embedded media processor core to build the future high-end computing machine or the supercomputer. However the embedded solution also faces the operating system (OS) design challenge which the thread invoking overhead is higher for fine-grained scientific workload, the message pa...

Abstract The advancement of multi-core processor technology has changed the course of computing and enabled us to maximize the computing performance. In this study, we present an approach of task parallelism for the TwigStack algorithm on a multi-core system to find all occurrences of an XML query twig pattern in a large XML database. The TwigStack agorithm comprises two tasks. The first task i...

Approaching the theoretical performance of heterogeneous multicore architectures, equipped with specialized accelerators, is a challenging issue. Unlike regular CPUs that can transparently access the whole global memory address range, accelerators usually embed local memory on which they perform all their computations using a specific instruction set. While many research efforts have been devot...

Emergence of multi-core servers and the need for green computing has necessitated the resurgence of system virtualization. System virtualization has re-emerged as an answer to many critical issues being faced by the enterprise computing infrastructure. The issues that virtualization addresses are myriad, with the most popular one being server consolidation. Server consolidation deals with the p...

Until recently, the most software development tools and techniques were concentrated on views from the sequential model of program execution. Software developers who only familiarize with the sequential model will face unusual challenges of software projects that require multi-core or parallel programming. In this paper, we addresses the challenges that developers face as their projects requiri...

— MPSoCs are gaining popularity because of its potential to solve computationally expensive applications. A multi-core processor combines two or more independent cores (normally a CPU) into a single package composed of a single integrated circuit (Chip). However, as the number of components on a single chip and their performance continue to increase, a shift from computation-based to communicat...
