DOWNLOAD EBOOKThe performance of parallel cluster file systems suffers from many clients executing a large number of operations in parallel, because the I/O subsystem can be easily overwhelmed by the sheer amount of incoming I/O operations. This, in turn, can slow down the whole distributed system. Many optimizations exist that try to alleviate this problem. Client-side optimizations do preprocessing to minimize the amount of work the file servers have to do. Server-side optimizations use server-internal knowledge to improve performance. The PIOsimHD framework contains components to simulate, trace and visualize applications. It is used as a testbed to implement optimizations that could later be implemented in real-life projects. The main focus of this thesis lies on comparing existing client-side optimizations and newly implemented server-side optimizations like Server-Directed I/O, which provides server-side optimizations for both read and write operations. It chooses the order of I/O operations and tries to aggregate as many operations as possible to decrease the load on the I/O subsystem and improve overall performance. The Interleaved Two-Phase protocol is a modification of ROMIO's Two-Phase protocol, which only accesses contiguous file regions. HDSunshot is used to visualize and analyze some of the results. It is also used to evaluate different optimization techniques by analyzing the resulting traces. The results show that client-side optimizations do not necessarily beat server-side optimizations in terms of performance, but suggest that even simple server-side optimizations are good enough for many use cases. Integrating such optimizations into parallel cluster file systems could alleviate the need for sophisticated client-side optimizations. Due to their additional knowledge of internal workflows server-side optimizations may be better suited to provide high performance in general.

DOWNLOAD EBOOKThis book introduces the state-of-the-art in research in parallel and distributed embedded systems, which have been enabled by developments in silicon technology, micro-electro-mechanical systems (MEMS), wireless communications, computer networking, and digital electronics. These systems have diverse applications in domains including military and defense, medical, automotive, and unmanned autonomous vehicles. The emphasis of the book is on the modeling and optimization of emerging parallel and distributed embedded systems in relation to the three key design metrics of performance, power and dependability. Key features: Includes an embedded wireless sensor networks case study to help illustrate the modeling and optimization of distributed embedded systems. Provides an analysis of multi-core/many-core based embedded systems to explain the modeling and optimization of parallel embedded systems. Features an application metrics estimation model; Markov modeling for fault tolerance and analysis; and queueing theoretic modeling for performance evaluation. Discusses optimization approaches for distributed wireless sensor networks; high-performance and energy-efficient techniques at the architecture, middleware and software levels for parallel multicore-based embedded systems; and dynamic optimization methodologies. Highlights research challenges and future research directions. The book is primarily aimed at researchers in embedded systems; however, it will also serve as an invaluable reference to senior undergraduate and graduate students with an interest in embedded systems research.
