Calculate Linux is a Linux distribution optimized for fast deployment in an organization environment. It is based on the Gentoo Linux project and includes many preconfigured functions. Calculate Linux is distributed in five flavours: Calculate Linux Desktop (CLD), Calculate Directory Server (CDS), Calculate Linux Scratch (CLS), Calculate ...
This diagram represents five contiguous memory regions which each hold a pointer and a data block. The List Head points to the 2nd element, which points to the 5th, which points to the 3rd, thereby forming a linked list of available memory regions. A free list (or freelist) is a data structure used in a scheme for dynamic memory allocation.
Reliably sending a payload of data over a communications network requires sending more than just the payload itself. It also involves sending various control and signalling data required to reach the destination. This creates a so-called protocol overhead as the additional data does not contribute to the intrinsic meaning of the message. [5] [6]
Systems calculate the load average as the exponentially damped/weighted moving average of the load number. The three values of load average refer to the past one, five, and fifteen minutes of system operation. [5] Mathematically speaking, all three values always average all the system load since the system started up.
The Data Plane Development Kit (DPDK) is an open source software project managed by the Linux Foundation. It provides a set of data plane libraries and network interface controller polling-mode drivers for offloading TCP packet processing from the operating system kernel to processes running in user space .
GoboLinux is a Linux distribution whose most prominent feature is a reorganization of the traditional Linux file system.Rather than following the Filesystem Hierarchy Standard like most Unix-like systems, each program in a GoboLinux system has its own subdirectory tree, where all of its files (including settings specific for that program) may be found.
Copy-on-write (COW), also called implicit sharing [1] or shadowing, [2] is a resource-management technique [3] used in programming to manage shared data efficiently. Instead of copying data right away when multiple programs use it, the same data is shared between programs until one tries to modify it.
Gentoo for Mac OS X was the first non-Linux project of Gentoo and focused on making the Gentoo experience available on Apple's operating system by introducing the Portage system as a separate entity. This was roughly similar to Fink and MacPorts , but it used Portage instead of a Debian-like or Ports-like system.
