15-520: KSM may refer to: Kernel same-page merging , sharing identical computer memory pages among processes Khalid Sheikh Mohammed , terrorist held at Guantanamo Bay Kothagudem School of Mines , later University College of Engineering, Kakatiya University, India Kommando Spezialkräfte Marine , special forces of the German Navy Komunistický svaz mládeže or Communist Youth Union ,

30-456: A problem area for information systems implementation efforts. Users and information systems specialists tend to have different backgrounds, interests, and priorities. This is referred to as the user-designer communications gap. These differences lead to divergent organizational loyalties, approaches to problem solving, and vocabularies. Examples of these differences or concerns are below: Social scientific research on implementation also takes

45-405: A project manager using project management methodologies. Software Implementations involve several professionals that are relatively new to the knowledge based economy such as business analysts , software implementation specialists, solutions architects , and project managers. To implement a system successfully, many inter-related tasks need to be carried out in an appropriate sequence. Utilising

60-568: A step away from the project oriented at implementing a plan, and turns the project into an object of study. Lucy Suchman 's work has been key, in that respect, showing how the engineering model of plans and their implementation cannot account for the situated action and cognition involved in real-world practices of users relating to plans: that work shows that a plan cannot be specific enough for detailing everything that successful implementation requires. Instead, implementation draws upon implicit and tacit resources and characteristics of users and of

75-408: A well-proven implementation methodology and enlisting professional advice can help but often it is the number of tasks, poor planning and inadequate resourcing that causes problems with an implementation project, rather than any of the tasks being particularly difficult. Similarly with the cultural issues it is often the lack of adequate consultation and two-way communication that inhibits achievement of

90-457: Is at a premium. KSM was merged into the Linux kernel mainline in version 2.6.32, which was released on December 3, 2009. To be effective, the operating system kernel must find identical memory pages held by different processes. The kernel also needs to predict whether the pages are likely to update infrequently enough that the merging would be an efficient use of processor resources. A concern

105-733: Is different from Wikidata All article disambiguation pages All disambiguation pages Kernel same-page merging In computing , kernel same-page merging ( KSM ), also known as kernel shared memory , memory merging , memory deduplication , and page deduplication is a kernel feature that makes it possible for a hypervisor system to share memory pages that have identical contents between multiple processes or virtualized guests. While not directly linked, Kernel-based Virtual Machine (KVM) can use KSM to merge memory pages occupied by virtual machines . KSM performs memory deduplication by scanning through main memory for physical pages that have identical content, and identifies

120-517: Is that although memory usage is reduced, CPU usage is increased, thus negating potential increases in performance. Security is also a concern: Implementation In the information technology industry, implementation refers to the post-sales process of guiding a client from purchase to use of the software or hardware that was purchased. This includes requirements analysis, scope analysis, customizations, systems integrations, user policies, user training and delivery. These steps are often overseen by

135-455: The activity or program being implemented is described in sufficient detail so that independent observers can detect its presence and strength. In computer science, implementation results in software, while in social and health sciences, implementation science studies how the software can be put into practice or routine use. System implementation generally benefits from high levels of user involvement and management support. User participation in

150-515: The design and operation of information systems has several positive results. First, if users are heavily involved in systems design, they move opportunities to mold the system according to their priorities and business requirements, and more opportunities to control the outcome. Second, they are more likely to react positively to the change process. Incorporating user knowledge and expertise leads to better solutions. The relationship between users and information systems specialists has traditionally been

165-410: The desired results. Implementation is defined as a specified set of activities designed to put into practice an activity or program of known dimensions. According to this definition, implementation processes are purposeful and are described in sufficient detail such that independent observers can detect the presence and strength of the "specific set of activities" related to implementation. In addition,

195-432: The virtual pages that are mapped to those physical pages. It leaves one page unchanged, and re-maps each duplicate page to point to the same physical page, after which it releases the extra physical pages for re-use. It also marks both virtual pages as " copy-on-write " (COW), so that kernel will automatically remap a virtual page back to having its own separate physical page as soon as any process begins to write to it. KSM

225-431: Was originally intended to run more virtual machines on one host by sharing memory between processes as well as virtual machines. An experimental implementation of KSM by Red Hat found that 52 virtual instances of Windows XP with 1 GB of memory, could run on a host computer that had only 16 GB of RAM. Upon its implementation , users found KSM to also be useful for non-virtualized environments in which memory
