In distributed computing, a single system image (SSI) cluster is a cluster of machines that appears to be one single system. [1] [2] [3] The concept is often considered synonymous with that of a distributed operating system, [4] [5] but a single image may be presented for more limited purposes, just job scheduling for instance, which may be achieved by means of an additional layer of software ...
A process image is a copy of a given process's state at a given point in time. It is often used to create persistence within an otherwise volatile system. A common example is a database management system (DBMS). Most DBMS can store the state of its database or databases to a file before being closed down (see database dump). The DBMS can then ...
Although this will not work in all cases, for example when calling the wrong subroutine, it is the easiest way to find the problem if the program uses the incorrect results of a bad mathematical calculation.
OpenSSI can use SAN based clustered file systems for its root provided they provide a POSIX compatible file system interface. Lustre and Global File System have been tested, too. With a clustered file system, each node mounts the file system in parallel and access to the files goes directly from the node to the file system.
Python Imaging Library is a free and open-source additional library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats. It is available for Windows, Mac OS X and Linux. The latest version of PIL is 1.1.7, was released in September 2009 and supports Python 1.5.2–2.7. [3]
GYP (Generate Your Projects), a build automation tool (similar to CMake and Premake) designed to generate native IDE project files (e.g., Visual Studio, Xcode, etc.) from a single configuration; Image Packaging System (IPS), an advanced, cross-platform package management system primarily used in Solaris and OpenSolaris/illumos derivatives
Some of the metadata is maintained by the file system, for example last-modification date (and various other dates depending on the file system), location of the beginning of the file, the size of the file and if the file system backup utility has saved the current version of the files. These items cannot usually be altered by a user program.
