This document discusses centralized shared-memory architectures and cache coherence protocols. It begins by explaining how multiple processors can share memory through a shared bus and cached data. It then discusses the cache coherence problem that arises when caches contain replicated data. Write invalidate is introduced as the most common coherence protocol, where a write invalidates other caches' copies of the block. The implementation of write invalidate protocols with snooping and directory approaches is covered, focusing on supporting write-back caches through tracking shared state and bus snooping.

The processor-memory bandwidth in modern generation
processors is the important bottleneck due to a number of
processor cores dealing it through with the same bus/ processor-
memory interface. Caches take a significant amount
of energy in current microprocessors. To design an energyefficient
microprocessor, it is important to optimize cache
energy economic consumption. Powerful utilization of this
resource is consequently an important view of memory hierarchy
design of multi core processors. This is presently an
important field of research on a large number of research
issues that have suggested a number of techniques to figure
out the problem. The better contribution of this theme is the
assessment of effectiveness of some of the proficiencies that
were enforced in recent chip multiprocessors. Cache optimization
techniques that were named for single core processors
but have not been implemented in multi core processors
are as well tested to forecast their effectiveness.
MULTI-CORE PROCESSORS: CONCEPTS AND IMPLEMENTATIONSijcsit
This research paper aims at comparing two multi-core processors machines, the Intel core i7-4960X
processor (Ivy Bridge E) and the AMD Phenom II X6. It starts by introducing a single-core processor machine to motivate the need for multi-core processors. Then, it explains the multi-core processor machine and the issues that rises in implementing them. It also provides a real life example machines such as
TILEPro64 and Epiphany-IV 64-core 28nm Microprocessor (E64G401). The methodology that was used in comparing the Intel core i7 and AMD phenom II processors starts by explaining how processors' performance are measured, then by listing the most important and relevant technical specification to the
comparison. After that, running the comparison by using different metrics such as power, the use of HyperThreading
technology, the operating frequency, the use of AES encryption and decryption, and the different characteristics of cache memory such as the size, classification, and its memory controller. Finally, reaching to a roughly decision about which one of them has a better over all performance.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
