The document discusses the network emulation in NachOS. It simulates a basic network that allows sending and receiving fixed-length messages between nodes, but messages may be lost. It uses UNIX domain sockets to implement the network and defines functions for checking packet availability, sending packets, and receiving packets.

NETWORK IN NACHOS The operating system can use a simulated network to send and receive small, fixed – length messages. Message delivery is unreliable – messages may be lost.

We present a program that implemented to execute Adaptive merge sort algorithm in parallel on a GPU based system. Parallel implementation is used to get better performance than serial implementation in runtime perspective. Parallel implementation executes independent executable operation in parallel using large number of cores in GPU based system. Results from a parallel implementation of the algorithm is given and compared with its serial implementation on run time basis. The parallel version is implemented with CUDA platform in a system based on NVIDIA GPU (GTX 650)

Concurrency in Go by Denys Goldiner.pdf

Denys Goldiner

Go is a simple language with familiar syntax, but still, there are features, which implementation differs from most part of other programming languages. For example, the idea of CSP implemented as concurrency paradigm is used for parallelism in Go. It looks like a simple API, but under the hood, it is very complicated, but interesting mechanism. We will discuss, how it really works. (Slides from the speech on Kharkiv Go meetup 14 Sep 2019)

MongoDb scalability and high availability with Replica-Set

Vivek Parihar

One of the much awaited features in MongoDB 1.6 is replica sets, MongoDB replication solution providing automatic failover and recovery. MongoDB High Availabiltity with Replica Sets This talk will cover - • What is Replica Set? • Replication Process • Advantaged of Replica Set vs master/slave • How to set up replica set on production Demo This video is tutorial for setting up the MongoDb replica-set ion production environment. In this i took 3 instances which have already mongo installed and running. This tutorial consists-: 1.Setup the each instance of replica set 2.modify the mongodb.conf to include replica set information 3.configure the servers to include in replica set 4.then cross checking if we kill one primary then secondary becomes primary or not.

In this workshop we will make a brief introduction to the basics of networking: IP addresses, MAC addresses, DNS, DHCP. Concepts as a router, gateway and firewall are explained. Then we will see in practice how to share files on a local network (NFS, Samba), establish a FTP connection, or log on to another (Linux) machine remotely (SSH, VNC, RDP). Finally, we review some useful networking tools like ping, netstat, lookup, port scan, traceroute, whois.

Capturing NIC and Kernel TX and RX Timestamps for Packets in Go

ScyllaDB

Go gives us net.Dial and net.Listen for sending and receiving data at Layer 4. Now you will see how to send and receive raw packets directly to and from the NIC at Layer 1 to get timestamp information from timestamping-enabled NICs and when packets enter and leave the Linux kernel. Capturing these timestamps allows us to get better granularity when measuring latency and jitter instead of relying on time.Now() in userspace where that is subject to additional time introduced by the OS and Go runtime schedulers.

Socket programming

Rajivarnan (Rajiv)

Introduction This Tutorial is On Socket Programming In C Language for Linux. Instructions Give Below will only work On Linux System not in windows. Socket API In windows is called Winsock and there we can discuss about that in another tutorial. What is Socket? Sockets are a method for communication between a client program and a server program in a network. A socket is defined as "the endpoint in a connection." Sockets are created and used with a set of programming requests or "function calls" sometimes called the sockets application programming interface (API). The most common sockets API is the Berkeley UNIX C interface for sockets. Sockets can also be used for communication between processes within the same computer.

Synthetic Fiber Construction in lab .pptx

Pavel ( NSTU)

Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...

Levi Shapiro

Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg Dear Dr. Kornbluth and Mr. Gorenberg, The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation. This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or unwillingness to rectify this violation through action requires accountability. Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots. The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee. • The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act. • The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X. • The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
