Download file to see previous pages A parallel system is a computer with more than one processor for parallel processing. Although there are many kinds of parallel computers, they are basically distinguished by the kind of interconnection between the processor, known as processing elements (PES), and the memory. One major way to classify parallel computers is based on their memory architectures. Shared memory based parallel computing systems have multiple processors that access all available memory as a global address space. The distributed system is a network of a set of asynchronously connected computing devices. Communication in DS is either through shared memory or through messages. In wide-spread distributed systems, work and information are physically distributed, implying that computing needs should be distributed. Along with the improvement in response time, this system contributes to offering local control over data. With this solid background of multiprocessor systems, parallel computing, distributed systems, and shared memory; speed-up performance law such as the Amdahl’s law was introduced to throw light on algorithm design for speed-up and operational efficiency of the parallel system. Concurrency is another important factor which enables distributed systems to share memory; and to better understand its execution, Dining philosophers’ algorithm Bully’s algorithm and Logical clocks were introduced.
The memory organization of the parallel system also has a profound impact on algorithm design. In systems in which memory is distributed among the processors, the interconnection topology is the major factor in the design of an algorithm to solve a given problem. As the number of processors becomes larger, it is increasingly difficult to design algorithms to achieve high speed-up. On the other hand, systems with a global shared memory provide more flexibility for algorithm design, although memory module contention can adversely affect performance and the algorithm should be designed to minimize it (Yuan 1996). ...Download file to see next pagesRead More

PSM: Distributed systems

...significant is related to the uptime and availability of services at all times. In addition, cloud computing is also efficient for handling large data sets incorporated by the services associated with web 2.0. The pay for use business model facilitates academic institutions to analyze data in terabytes by distributed computing over hundreds of computers in only short time cost (Han 2010). Furthermore, the integration of Web 2.0 and semantic web has produced a new revolutionary e-portfolio. Previously, the development and implementation approach of e-portfolios have faced various challenges and limitations. However, a research by (Kim, Ng et al. 2010) on a design based on Private-Public data index systems...

Semantic Web + Parallel Distributed data

..., it is due to note that GPU (Graphical Processing Units) were originally hardware blocks which were optimized for a small set of graphics operations. At the present where the GPU’s are more programmable, the approaches to computing and data warehousing is different. This has enabled the use of improvised tools in the CUDA architecture which the data implements a parallel computing on a GPU making it more straight forward and fast.

Distributed Systems

...DISTRIBUTED SYSTEMS Java RMI RMI is an abbreviation for Remote method invocation. It allows us to implement RPC style applications in java. In fact, it's a technology which is native to java. RMI applications (client applications) invoke methods in remote objects wherein a remote object is one which resides in another JVM. The other JVM can be on the same machine or any other machine on the network. However, the only thing it requires is for the JVM to be present at both sides. It implements remote interface developed by us and also language specifications, which is used by the server to provide the service as per the method call. It comprises of a stub and skeleton each at the client and server side respectively, wherein the stub... ...

Distributed Systems assessment

...Communication between components in a distributed system may be done using "Message Passing", "Remote Procedure Call" or "Remote Object Invocation". The key features of these three mechanisms are given below: Message Passing: The Message Passing Interface (MPI) model refers to a computing model in which a computation comprises one or more processes that communicate by calling library routines to send and receive messages to and from other processes. In most implementations of MPI, a fixed set of processes is created at program initialization, and one process is created per processor. However, these processes may execute different programs. Hence, the MPI programming model is also referred to as Multiple Program Multiple Data (MPMD... to the...

Parallel-distributed processing in memory/cognition

...RUNNING HEAD: PDP in Memory and Cognition PARALLEL DISTRIBUTED PROCESSING IN MEMORY AND COGNITION: A BRIEF OVERVIEW Mentor’s Institute and department ABSTRACT: Parallel distributed processing is now widely contemplated as the chief mechanisms through which the brain is able to assimilate information and form it into complex patterns. Its role in memory, language acquisition and in the creation of learning patterns has also been demonstrated. This method is fast gaining ground due to its high variability, and more universality than the traditional one mode or one plane thinking models of the brain. PARALLEL DISTRIBUTED PROCESSING IN...
