  1. Mass Storage Control Protocol

    Unreferenced date December 2009 The Mass Storage Control Protocol MSCP was a Protocol computing protocol designed by Digital Equipment Corporation of Maynard, Massachusetts Maynard , Massachusetts for the purposes of controlling their high end mass storage options. First implemented in the VMScluster HSC50 hierarchical storage controller, the protocol quickly spread throughout the entire line of mass storage controllers built by DEC. The UDA50 was an implementation of MSCP built on a Unibus card other implementations for example, the RQDX stretched down to the Q bus and small, 5 megabyte disk drives and even diskette s. Designed to minimize the amount of Central processing unit CPU involvement, the protocol depended upon two queues. Into one queue were placed packet information technology packet s which fully described the commands to be executed by the mass storage subsystem. To initiate an I O request, the CPU had only to create a small data structure in memory, append it to a send queue, and if that was the first packet in the send queue, wake the MSCP controller. After the command was executed, an appropriate status packet would be placed into the second queue to be read by the CPU. Interrupts to the CPU a costly operation were not needed so long as further command packets remained in the command queue and the response queue was not in danger of over flowing. I O space reads and writes to the MSCP controller, a less expensive but still costly operation, were similarly minimized. Because MSCP packets were deliberately designed to resemble the packets exchanged on the VMScluster interconnects, it was a very inexpensive operation to ship storage requests around a VMScluster for remote execution this greatly facilitated the creation of large scale VMSclusters. The dependence upon in memory packets and the minimization of interrupts and I O space reads and writes greatly facilitated remote operations.

    About the scientific concept the Liturgical Mass Mass liturgy other uses distinguish matter Classical mechanics cTopic Fundamental concepts In physics , mass from lang grc commonly refers to any of three properties of matter , which have been shown experimentally to be equivalent inertial mass, active gravitational mass, and passive gravitational mass. Although mass must be distinguished from ... matter exhibit mass, it is also the case that many types of energy which are not matter such as potential energy , kinetic energy , and trapped electromagnetic radiation photon s also exhibit mass. Thus, all matter has the property of mass, but not all mass is associated with identifiable matter. In everyday usage, mass is often used interchangeably with weight , and the units of weight are often ... use, however, the two terms refer to Mass versus weight different , yet related, properties of matter. The inertial mass of an object determines its acceleration in the presence of an applied force. According to Newton s second law of motion , if a body of fixed mass m is subjected to a force F , its acceleration a is given by F m . A body s mass also determines the degree to which it generates or is affected by a gravitational field . If a first body of mass m sub 1 sub is placed at a distance r from a second body of mass m sub 2 sub , each body experiences an attractive force F whose ... referred to as gravitational mass when a distinction is necessary, M is used to denote the active gravitational mass and m the passive gravitational mass .
