Nowadays multiprocessor system has received a lot of attention because of its efficiency and reliability, which play an important role in success of multiprocessor systems. Hence, there is a necessity for developing efficient scheduling algorithms. Therefore, various researches have been done in different areas of scheduling of multiprocessor system. This paper evaluates the performance of homo...

AARON D. BLOCK: Adaptive Multiprocessor Real-Time Systems (Under the direction of James H. Anderson) Over the past few years, as multicore technology has become cost-effective, multiprocessor systems have become increasingly prevalent. The growing availability of such systems has spurred the development of computationally-intensive applications for which single-processor designs are insufficien...

The development of computing systems with large numbers of processors has been motivated primarily by the need to solve large, complex problems more quickly than is possible with uniprocessor systems. Traditionally, multiprocessor systems have been uniprogrammed, i.e., dedicated to the execution of a single set of related processes, since this approach provides the fastest response for an indiv...

Operating-system kernels are critical software components in computer systems. Building secure, safe and reliable computer systems is facilitated by having strong kernel correctness guarantees. Such guarantees can be obtained by formally verifying a kernel down to the implementation level. Kernel verification has attracted much research interest. For example, the L4.verified project has proved ...

Due to the ever-growing requirements in high performance data computation, multiprocessor systems have been proposed to solve the bottlenecks in uniprocessor systems. Developing efficient multiprocessor systems requires effective exploration of design choices like application scheduling, mapping, and architecture design. Also, fault tolerance in multiprocessors needs to be addressed. With the a...

Multicore and multiprocessor systems with dynamic voltage scaling architectures are being used as one of the solutions to satisfy the growing needs of high performance applications with low power constraints. An important aspect that has propelled this solution is effective task/application scheduling and mapping algorithms for multiprocessor systems. This work proposes an energy aware, offline...

Most current multiprocessor le systems are designed to use multiple disks in parallel using the high aggregate bandwidth to meet the growing I O requirements of parallel scienti c applications Many multiprocessor le systems provide applications with a conventional Unix like interface allowing the application to access multiple disks transparently This interface conceals the parallelism within t...

Both parallel and distributed network environment systems play a vital role in the improvement of high performance computing. The primary concern when analyzing these systems is multiprocessor task scheduling. This paper addresses the problem of efficient multiprocessor task scheduling. A multiprocessor task scheduling problem is represented as directed acyclic task graph (DAG), for execution o...

The ongoing transition from uniprocessor to multi-core computers requires support from the operating system kernel. Although many general-purpose multiprocessor operating systems exist, there is a large number of specialized operating systems which require porting in order to work on multiprocessors. In this paper we describe the multiprocessor port of a cluster operating system kernel from a p...

Task Scheduling [1] is the allocation of resources over time to perform a collection of tasks. Real -time systems make use of scheduling algorithms to maximize the number of real -time tasks that can be processed without violating timing constraints. A scheduling algorithm provides a schedule for a task set that assigns tasks to processors and provides an ordered list of tasks. The schedule is ...
