A Parallel Execution Distributed Middleware of Enterprise Applications
ISBN: 9783838336404 / Angielski / Miękka / 108 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. A typical enterprise uses a local area network of computers to perform its business. During the off-working hours, the computational capacities of these networked computers are underused or unused. In order to utilize this computational capacity an application has to be recoded to exploit concurrency inherent in a computation which is clearly not possible for legacy applications without any source code. This thesis presents the design an implementation of a distributed middleware which can automatically execute a legacy application on multiple networked computers by parallelizing it. A...

Multitouch Draw A Secret
ISBN: 9783847309819 / Angielski / Miękka / 88 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Draw A Secret password systems have recently come into vogue, primarily in the role of protecting a users cellular smart phone from external infiltration in lieu of a password. However, these password systems are only enabled for single touch operation; that is to say, a user may only draw one pattern, with only one finger. Brute forcing these passwords thereby becomes trivial in the context of password complexity. This thesis implements a Draw A Secret system utilizing consumer-grade video hardware to collate multiple patterns synchronously and then authenticate the user at a later point....

TCP Offload through Connection Handoff
ISBN: 9783838314457 / Angielski / Miękka / 116 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. TCP offload is a technique to improve TCP/IP networking performance of a network computer system by moving (parts of) TCP processing from the host processor to the network interface. There are several ways to achieve offload. The typical full offload moves all TCP functionalities to the network interface, and TCP processing is performed exclusively on the network interface. However, when the network interface has limited processing power, full offload creates a bottleneck at the network interface and degrades system performance. In contrast, TCP offload based on connection handoff ...

Duper Scalar Processor
ISBN: 9783844329490 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This paper proposes an architecture that brings in a new dimension to instruction level parallelism. The operating system in todays machines does all the decision making as to how the instructions in a task can be parallelized by deciding which task gets assigned to which core. The hardware support for exploiting instruction level parallelism is very small and has very little decision making power. Most recently dynamic scheduling of the instructions paved the pathway for major hardware changes and hence the decision making power shared. But the problem still persists. The operating has no...

Mutual Exclusion Algorithms
ISBN: 9783659179389 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Multiprocessing systems are programmed cleanly using Critical sections. When a process desires to access some shared data it first gets mutual exclusive access to critical sections for reliable outcome as processes may possibly manipulate the data. This work investigates how critical section problem can be solved easily and efficiently for multiprocessing and distributed systems. This report presents an algorithm that can solve the problem in single processing, multiprocessing and distributed systems efficiently with minimal changes. For distributed systems we introduce message passing...

Fuzzy Approach for Sjf CPU Scheduling
ISBN: 9783659291388 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In this book a Fuzzy-based Algorithm for the prediction of next CPU burst has been proposed. This algorithm uses the intelligent fuzzy system to estimate the execution time of a process based on its past behavior. The heart of this system is a database which contains if-then rules. Further, the comparative analysis of the Exponential Average Algorithm and the Fuzzy -based algorithm reflect that the Fuzzy-based approach is more optimal, thus it predicts more closer values to the real CPU-burst than the Exponential Average Algorithm.

Simple Interface for Windows 98
ISBN: 9783844316506 / Angielski / Miękka / 52 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Interrupts are an important part of computer architecture. Each computer design has its own interrupt mechanism, but several functions are common. Interrupt need to be hooked for several reasons. One reason is to change the behavior of the system services exported by the operating system. By hooking the software interrupts, monitoring applications can be written. Hooking can prove useful in studying operating system internals. This can also serve as a way to hook system services. In this work, interrupt gate be hooked under Windows 98 by saving the old vector of its entry and add a new vector...

Method and System for Multidimensional Data Visualization
ISBN: 9783659334702 / Angielski / Miękka / 52 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Visualization of a system state as a whole suggests reflection of all variables together on one "integral" image. This applies to both static and dynamic systems changing its state over time. Maximum number of dimensions reflected on an image is limited by dimensionality of the presentation tools like a sheet of paper or computer screen. Therefore, to visualize a static state dimensionality of an image cannot exceed three and, in the case of dynamic data, only two dimensions given that one of them is needed to show time. A method and software system that fulfill the above requirements are...

Advanced Caching Methods for Multiple CPU Systems
ISBN: 9783659296888 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. For a heterogeneous environment where different CPU are assigned or performing different type of tasks requires some sort of performance assistance considering almost same type of resources. One possibility is to decouple the cache mechanism and to consider the usages of second level cache for every CPU to increase the performance and to make availability of common resources. This decoupling of memory significantly increases the performance by sharing and parallel reusing of the resources which is considered as the cache lines for multiple CPU at the same time to an embedded system. Of...
