Message-passing strengths and weaknesses: message can be exchanged between the processes either directly or indirectly through a common mailbox. It is useful for exchanging smaller amounts of data and easier to implement for inter-computercommunication. However, its speed is slower than shared-memory...
In computer science,Kernel is a computer program that is a core or heart of an operating system.Before discussing kernel in detail, let's first understand its basic, i.e., Operating system in a computer. Operating System Anoperating systemor OS is system software that works as an interface ...
Operating System Tutorial provides the basic and advanced concepts of operating system . Our Operating system tutorial is designed for beginners, professionals and GATE aspirants. We have designed this tutorial after the completion of a deep research about every concept. The content is described in d...
Message Queuing Message queuing offers a loosely-coupled approach to building distributed applications which can be implemented in a synchronous or asynchronous manner. Because messages are application defined, there is no restrictive structure specifying the way in which applications must be written. Inste...

Using SystemTap What issystemtap? SystemTap is a tracing and probing tool that allows users to study and monitor the activities of the operating system (particularly, the kernel) in fine detail. It provides information similar to the output of tools like netstat, ps, top, and iostat; however...
The list of these concepts is given below: Classes Objects Encapsulation Abstraction Inheritance Polymorphism Apart from these six basic pillars of OOPs, there are two more important concepts in this programming system, i.e., message passing and dynamic binding. We will discuss all these components...
Message passing interface (MPI) HPC workloads rely on a message passing interface (MPI), a standard library and protocol for parallel computer programming that allows users to communicate between nodes in a cluster or across a network. High-performance computing (HPC) relies on conventional bits an...
Although Swift 6 is looming on the horizon, the 5.x releases still have a lot to give – simpler ways to use if and switch, macros, noncopyable types, custom actor executors, and more are all coming in Swift 5.9, making yet another mammoth release. In this article I’ll walk you ...
This article reports on the latest news in Linux kernel development. Pekka Enberg is reportedly developing a virtualization tool for booting a virtual system on a running Linux box. Tony Ibbs has released a message-passing framework called KBUS designed to support software operating on embedded ...
