Container (virtualization)
OS-level virtualization is an operating system (OS) paradigm in which the kernel allows the existence of multiple isolated user space instances, called ''containers'' (LXC, Solaris containers, Docker, Podman), ''zones'' ( Solaris containers), ''virtual private servers'' ( OpenVZ), ''partitions'', ''virtual environments'' (VEs), ''virtual kernels'' ( DragonFly BSD), or ''jails'' ( FreeBSD jail or chroot jail). Such instances may look like real computers from the point of view of programs running in them. A computer program running on an ordinary operating system can see all resources (connected devices, files and folders, network shares, CPU power, quantifiable hardware capabilities) of that computer. However, programs running inside of a container can only see the container's contents and devices assigned to the container. On Unix-like operating systems, this feature can be seen as an advanced implementation of the standard chroot mechanism, which changes the apparent roo ...

Delta Update
A delta update is a software update that only requires the user to download those parts of the software's code which are new, or have been changed from their previous state, in contrast to having to download the entire program. The use of delta updates can save significant amounts of time and computing bandwidth. The name ''delta'' derives from the mathematical science use of the Greek letter delta, Δ or δ to denote ''change''. By using a delta update, a program can be updated more quickly and efficiently. For example: An auto racing simulation game has a size of 300 megabytes; it is updated to include a new racetrack, and the body of code which inserts the new racetrack into the game has a size of two megabytes; the game may use a delta update, which would require the download of only the two megabytes of new code, instead of a total download of 302 megabytes. Uses Linux Fedora Linux has supported binary delta updates by default using the yum presto plugin since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wayland (display Server Protocol)
Wayland is a communication protocol that specifies the communication between a display server and its clients, as well as a C library implementation of that protocol. A display server using the Wayland protocol is called a ''Wayland compositor'', because it additionally performs the task of a compositing window manager. Wayland is developed by a group of volunteers initially led by Kristian Høgsberg as a free and open-source community-driven project with the aim of replacing the X Window System with a modern, secure simpler windowing system in Linux and other Unix-like operating systems. The project's source code is published under the terms of the MIT License, a permissive free software licence. As part of its efforts, the Wayland project also develops a reference implementation of a Wayland compositor called '' Weston''. Overview The Wayland Display Server project was started by Red Hat developer Kristian Høgsberg in 2008. Beginning around 2010, Linux desktop graph ...

Solution Stack
In computing, a solution stack or software stack is a set of software subsystems or components needed to create a complete platform such that no additional software is needed to support applications. Applications are said to "run on" or "run on top of" the resulting platform. For example, to develop a web application, the architect defines the stack as the target operating system, web server, database, and programming language. Another version of a software stack is operating system, middleware, database, and applications. Regularly, the components of a software stack are developed by different developers independently from one another. Some components/subsystems of an overall system are chosen together often enough that the particular set is referred to by a name representing the whole, rather than by naming the parts. Typically, the name is an acronym representing the individual components. The term "solution stack" has, historically, occasionally included hardware components ...

UEFI
UEFI (Unified Extensible Firmware Interface) is a set of specifications written by the UEFI Forum. They define the architecture of the platform firmware used for booting and its interface for interaction with the operating system. Examples of firmware that implement these specifications are AMI Aptio, Phoenix SecureCore, TianoCore EDK II and InsydeH2O. UEFI replaces the BIOS which was present in the boot ROM of all personal computers that are IBM PC-compatible, although it can provide backwards compatibility with the BIOS using CSM booting. Intel developed the original ''Extensible Firmware Interface'' (''EFI'') specifications. Some of the EFI's practices and data formats mirror those of Microsoft Windows. In 2005, UEFI deprecated EFI 1.10 (the final release of EFI). UEFI is independent of platform and programming language, but C is used for the reference implementation TianoCore EDKII. History The original motivation for EFI came during early development of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carry-less Multiplication
The carry-less product of two binary numbers is the result of carry-less multiplication of these numbers. This operation conceptually works like long multiplication except for the fact that the carry is discarded instead of applied to the more significant position. It can be used to model operations over finite fields, in particular multiplication of polynomials from GF(2) 'X'' the polynomial ring over GF(2). The operation is also known as an XOR multiplication, as carry-discarding addition is equivalent to an exclusive or. Definition Given two numbers \textstyle a=\sum_i a_i2^i and \textstyle b=\sum_i b_i2^i, with a_i,b_i\in\ denoting the bits of these numbers. Then the carry-less product of these two numbers is defined to be \textstyle c=\sum_i c_i2^i, with each bit c_i computed as the exclusive or of products of bits from the input numbers as follows: : c_i=\bigoplus_^i a_jb_ Example Consider ''a'' = 101000102 and ''b'' = 100101102, with all numbers given in binary.

CLMUL
Carry-less Multiplication (CLMUL) is an extension to the x86 instruction set used by microprocessors from Intel and AMD which was proposed by Intel in March 2008 and made available in the Intel Westmere processors announced in early 2010. Mathematically, the instruction implements multiplication of polynomials over the finite field GF(2) where the bitstring a_0a_1\ldots a_ represents the polynomial a_0 + a_1X + a_2X^2 + \cdots + a_X^. The CLMUL instruction also allows a more efficient implementation of the closely related multiplication of larger finite fields GF(2''k'') than the traditional instruction set. One use of these instructions is to improve the speed of applications doing block cipher encryption in Galois/Counter Mode, which depends on finite field GF(2''k'') multiplication. Another application is the fast calculation of CRC values, including those used to implement the LZ77 sliding window DEFLATE algorithm in zlib and pngcrush. ARMv8 also has a version of CLMUL. S ...

Xeon E3
Xeon ( ) is a brand of x86 microprocessors designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded system markets. It was introduced in June 1998. Xeon processors are based on the same architecture as regular desktop-grade CPUs, but have advanced features such as support for ECC memory, higher core counts, more PCI Express lanes, support for larger amounts of RAM, larger cache memory and extra provision for enterprise-grade reliability, availability and serviceability (RAS) features responsible for handling hardware exceptions through the Machine Check Architecture. They are often capable of safely continuing execution where a normal processor cannot due to these extra RAS features, depending on the type and severity of the machine-check exception (MCE). Some also support multi-socket systems with two, four, or eight sockets through use of the Ultra Path Interconnect (UPI) bus. Overview The ''Xeon'' brand has been maint ...
