...deadlock is detected, the solver agent is used to resolve the deadlock . Introduction The onset of multicore processors forces the programmers to use multiple threads in order to take advantage of hardware parallelism. Java is one of the first languages to make multithreading available to developers. Along with advantages of concurrent systems and multithreading, there are some challenges involved. Java has inter-process communication model which means it has set of methods for exchange of data among multiple threads and processes. It is based on shared data structures and meshes well with hardware architectures in which multiple cores share memory. However Java is susceptible to deadlocks. Deadlock is a condition under which the entire program is halted as each thread in a set attempts to acquire a lock already held by another thread in a set. Java is susceptible to deadlocks because (a) threads exchanges information by sharing variables that they lock with mutex locks and (b) the locking mechanism interacts with other language features, such as aliasing. Consider a simple banking transaction example. [pic] Figure 1: Deadlock scenario in banking transaction .In this case if there are two threads attempting to run transfer(a,b) and transfer(b,a) at the same time then deadlock is going to occur because both threads try to acquire the resources in reverse order. Once a program is deadlocked the source of deadlock is difficult to determine making it difficult to resolve the...

...CASE STUDY 5.1 Using the ‘Technology as Experience’ Framework Introduction To show how the Technology as Experience framework (introduced in Chapter 5) can be used to think about and inform design, two case studies are presented here. Both used it to guide their initial ideas for the design of two different websites: (i) an online fundraising site and (ii) a site that reviews men’s clothing, intended to appeal to men who do not enjoy shopping. Both were written by students as part of a graduate course in Human-Computer Interaction and hence it should be noted are only hypothetical websites (see the end of the case study for the assignmenti ). The first was written by Heather Collins when she was a graduate student at Indiana University. She used primarily the sensory and compositional threads of the framework, leading to insights on how fundraising organizations can maximize their website to tell a compelling story to a potential donor that is balanced in content and emotion. Her design combines elements of storytelling, appropriate emotional triggers, and a welcoming atmosphere to encourage potential donors to act by making a donation, volunteering their time, telling their friends, or attending a related event. Through this process, the donor can create a meaningful connection to a cause or problem directly impacting their community. The personal connection makes the online donation experience pleasurable for the user. The second was written by Aaron Loehrlein when he was also...

A process needs certain assets, including CPU time, memory, documents, and I/O gadgets, to achieve its undertaking. The working framework is in charge of the accompanying exercises regarding process administration i.e. process creation and erasure, process suspension and resumption (scheduling), procurement of instruments for process synchronization and process correspondence. Process administration is normally performed by the bit. In numerous cutting edge working frameworks, there can be more than one occurrence of a system stacked in memory in the meantime; for instance, more than one client could be executing the same project, every client having separate duplicates of the system stacked into memory. With a few projects, it is conceivable to have one duplicate stacked...

...Working Together from Afar A Study on the Effectiveness of the Communication Strategies and Flow used in a Virtual Office By Patricia Camille C. Duremdes Submitted December 13, 2014 to Dr. Rosario M. Baria Abstract Communication is important in any group that has a common goal (Simon, 1976). It is a requirement in a situation where people with different tasks have to coordinate to work as one. While achieving effective communication is relatively easy in a traditional organization, organizations that exist in cyberspace have to find alternative ways to communicate effectively due to the limitations caused by the long distances between the members. This study was conducted to find out whether or not the communication within a virtual writing service of 14 workers is effective. The study used both qualitative and quantitative methods in gathering information. Information about the virtual office’s communication strategies and flow were obtained through first-hand observation, while the effectiveness of communication was determined through questionnaire results. The results indicated that the communication strategies and flow used in the office were effective, as a vast majority of the respondents had positive views on the communication within their office.

Introduction The European Commission (EC) convicted eleven companies in the thread industry for arranging cartels for customers in Benelux, the Nordic countries and the EEA in 2005. The 23 producers investigated are from Germany, Belgium, the Netherlands, France, Switzerland and the United Kingdom and were fined to a total of 43.5 million € (European Commission, 2005). Industrial thread itself is a kind of thin yarn that is used for sewing. It is therefore a main component in the production of various products, such as clothes, home furnishings, mattresses, footwear and others. Additionally, the production of automotive seats and seatbelts can be assigned to the so called automotive thread. Both markets together amounted to around 6 billion € in in sales worldwide in 2000.

...Case Study 3: Managing Contention for Shared Resources on Multicore Processors By Ja’Kedrick L. Pearson Professor Hossein Besharatian CIS 512 June 2, 2013 Memory contention Memory contention is a state an OS memory manager can reside in when to many memory requests are issued to it from an active application possibly leading to a DOS condition specific to that application. A test was run on a group of applications several times, on three different schedules, each with two different parings sharing a memory domain. The three pairing permutations afforded each application an opportunity to run with each of the other three applications with the same memory domain. The three applications being discussed in this paper are the Soplex, Sphinx, and the NAMD. The Soplex is a linear programming (LP) solver based on the revised simplex algorithm. It features preprocessing techniques, exploits sparsity, and offers primal and dual solving routines. It can be used as a standalone solver reading MPS or LP format files as well as embedded into other programs via a C++ class library. Sphinx is an open source full text search server, designed from the ground up with performance, relevance (aka search quality), and integration simplicity in mind. It's written in C++ and works on Linux (RedHat, Ubuntu, etc), Windows, MacOS, Solaris, FreeBSD, and a few other systems (Sphinx Technologies, 2013). NAMD is a parallel molecular dynamics code designed for...

...An effective IT infrastructure can suppor t a business vision and strategy; a poor, decentralized one can break a company. More and more companies are turning to off-the-shelf ERP solutions for IT planning and legacy systems management. The authors have developed a framework to help managers successfully plan and implement an ERP project. A Critical Success Factors Model For ERP Implementation FROM THE TRENCHES: Wolfgang B. Strigel, editor • wstrigel@spc.ca Christopher P. Holland and Ben Light, Manchester Business School ompanies are radically changing their information technology strategies by purchasing prepackaged software instead of developing IT systems in-house. Price Waterhouse predicts that by 2000, two-thirds of all business software will be bought off the shelf. More specifically, Deloitte and Touche states that businesses prefer to replace legacy systems with enterprise resource planning systems. According to AMR Research, the ERP systems market was $15.68 billion in 1997 and is likely to increase at a compound rate of 36 percent, to $72.63 billion, by 2002. The associated consultancy market is approximately $30 billion. These statistics clearly indicate a shift in the ERP market. There are mixed reports concerning the outcome of ERP projects. Successful ERP implementations are certainly publicized, such as Pioneer New Media Technologies (see http://Datamation.com/PlugIn/erp/index.htm) and Monsanto,1 but less successful projects have led to bankruptcy proceedings...

...it uses is called the scheduling algorithm. These topics form the subject matter of the following sections. Many of the same issues that apply to process scheduling also apply to thread scheduling, although some are different. Initially we will focus on process scheduling. Later on we will explicitly look at thread scheduling. 2.5.1 Introduction to Scheduling Back in the old days of batch systems with input in the form of card images on a magnetic tape, the scheduling algorithm was simple: just run the next job on the tape. With timesharing systems, the scheduling algorithm became more complex because there were generally multiple users waiting for service. Some mainframes still combine batch and timesharing service, requiring the scheduler to decide whether a batch job or an interactive user at a terminal should go next. (As an aside, a batch job may be a request to run multiple programs in succession, but for this section, we will just assume it is a request to run a single program.) Because CPU time is a scarce resource on these machines, a good scheduler can make a big difference in perceived performance and user satisfaction. Consequently, a great deal of work has gone into devising clever and efficient scheduling algorithms. With the advent of personal computers, the situation changed in two ways. First, most of the time there is only one active process. A user entering a document on a word processor is unlikely to be simultaneously compiling a program in the background....

...implementing lean techniques in a textile industry has been taken up as a challenge. We have chosen a combination of value stream mapping (VSM), 5S, kanban, kaizen, poka-yoke, and visual controls to improve the processes. The findings of this study reveal that a thorough analysis of the process, setup, and changeover time (CO), use of colour coding for identification of volume-mix, use of kaizen and quality circles which empower the workforce, are some of the various keys to a successful lean implementation in a textile industry. Keywords:Project manegement; lean manufacturing; agile manufacturing; value stream mapping; VSM; supply chain management. 1 Introduction What Is a Project Manager? SECTION 1: INTRODUCTION TO PROJECT MANAGEMENT Project management is the art of matching a project's goals, tasks, and resources to accomplish a goal as needed. We say "as needed" because one has limited time, money, and resources (human and machinery) with which to accomplish a goal. One can think of a project as a process. Figure 1 shows this process as a simplified block diagram. Figure 1: Simple Project Management System The process involves inputs and outputs. Successful projects "do the right things, with the right tools, and in the right way". SECTION 2: STAGES OF A PROJECT AND HOW TO COMPLETE THEM Stage 1: Defining the goals of the project: Garbage in equals garbage out. If you do not start a project with the correct goal(s), it is not likely you will accomplish the goal(s)...
