  • In this paper we investigate and build up three methods for transforming sequential processes of a net system into concurrent ones. These methods are based on: trace languages, shiftleft and case graphs. They are also presented by detail algorithms and can be applied to other models of concurrent systems. Keywords: net system, reliance alphabet, trace language, maximal concurrent steps, case graph. 1. Introduction The behaviour of a system often is represented by the set of the system’s processes. ...

  • If you're looking to take full advantage of multi-core processors with concurrent programming, this practical book provides the knowledge and hands-on experience you need. The Art of Concurrency is one of the few resources to focus on implementing algorithms in the shared-memory model of multi-core processors, rather than just theoretical models or distributed-memory architectures.

  • With the introduction of multicore devices such as the iPad 2 and the quad-core Mac- Book Pro, writing multithreaded apps that take advantage of multiple cores on a device has become one of the biggest headaches for developers. Take, for instance, the introduction of iPad 2. On the launch day, only a few applications, basically those released by Apple, were able to take advantage of its multiple cores. Applications like Safari performed very well on the iPad 2 compared to the original iPad, but some third-party browsers did not perform as well as Safari.

  • Surrounded as we are by software for personal computers, electronic gadgets and entertainment websites, it is easy to lose sight of the massive amount of software embedded in critical systems. I was surprised when I found out that the computerized systems in modern cars have half a million lines of code, and that electronics account for 25% of their cost and this percentage is forecast to increase.

  • When the predicates table does not fit on one node, joins can no longer be performed strictly locally. Instead, the table must be horizontally partitioned. A tuple can only immediately join with the local partition at the node and must be shipped to other nodes to complete the join. Once the original tuple has reached every node that contains a partition of the table, it can be dropped and results can be forwarded to the root.

  • When you create a geodatabase, as you did in Exercise Add a database server to the Catalog tree and create a geodatabase, there is no data in it. You must add data to new geodatabases either by creating new datasets, importing data, or copying data from one geodatabase and pasting it into another. In this exercise, you will create a feature dataset, then import data from a personal geodatabase to populate it. You will also copy data from a file geodatabase and paste it into your new geodatabase. After the data is loaded, you will update the database statistics....

  • MODEL CHECKING OF FINITE-STATE SYSTEMS One way to show that a program or system meets the designer’s specification is to manually construct a proof using axioms and inference rules in a deductive system such as temporal logic, a first-order logic capable of expressing relative ordering of events. This traditional, manual approach to concurrent program verification is tedious and error-prone even for small programs.

  • Step by Step instructions to install Oracle Applications R12(12.1.1) on Oracle Enterprise Linux 5 are described in this article. This is a single node installation, meaning that the database, all product directories and AD core directories, and all servers (concurrent processing, forms, and Web) are installed on a single node under one common APPL_TOP. The database node and the Applications node can be installed on the same machine. This type of installation is generally used for small systems or for demonstration purposes.

  • Although many other models of concurrent and distributed systems have been developed since the introduction in 1964 Petri nets are still an essential model for concurrent systems with respect to both the theory and the applications. The main attraction of Petri nets is the way in which the basic aspects of concurrent systems are captured both conceptually and mathematically. The intuitively appealing graphical notation makes Petri nets the model of choice in many applications.
