device driver - a Whatis.com definition There is a virtual device driver for each main hardware device in the system, including the hard disk drive controller, keyboard, and serial and parallel ports. A device driver essentially converts the more general input/output instructions of the operating system to messages that the device type can understand. In Windows operating systems, a device driver file usually has a file name suffix of DLL or EXE. searchwin2000.techtarget.com /sDefinition/0,,sid1_gci211938,00.html   (673 words)

Nomad Home Page Nomad avoids sending extra messages by relying on the communication intrinsic to its distributed file system (which is needed for high disk I/O throughput and fault tolerance anyway). Nomad includes several important characteristics for modern cluster-oriented operating systems: scalability, efficient resource management across the cluster, efficient scheduling of parallel and distributed applications, distributed I/O, fault detection and recovery, protection, and backward compatibility. The mechanisms used to implement these characteristics include unique cluster-wide process identifications, process checkpointing and migration, co-scheduling of concurrent applications, and a distributed file system. www.cs.rutgers.edu /~ricardob/nomad.html   (514 words)

Parallel network communications protocol using token passing - Patent 5742812 In general, in a message passing computer or in a distributed computer system, the interconnection network connecting the various file server nodes to each other and to the requesting sites may not guarantee any absolute ordering of the access component messages received at each file server node. The token is generated by the primary node and relayed from the primary node to the next subsequently higher numbered file server node, whether or not that higher-numbered node forms part of the request (i.e., regardless of whether the node receives an access component message for this access). The method of claim 6, wherein each token comprises a token counter representing the number of tokens passed by the preceding server, a request identifier identifying the request with which the token is associated, and the address of the next server to receive a request message. www.freepatentsonline.com /5742812.html   (6454 words)

eGovernment for Development - Malta eCustomer Care eTransparency Case Study All Maltese local councils can file complaints, suggestions or questions on behalf of citizens; for example those who lack IT skills or who do not possess a PC or WAP-enabled phone.   The limited opening hours of local councils in Malta (coinciding with the time when most Maltese are themselves working) was seen to be a constraint that held back the successful uptake of the original CCS system. eCustomer Care System in Malta: Enabling Online Complaints www.e-devexchange.org /eGov/eccsmalta.htm   (1446 words)

TITAN: A Next-Generation Infrastructure for Integrating Computing and Communication The unique thrust of the project is that rather than constructing the system out of an ensemble of specialized components, e.g., massively parallel processors, file servers, rendering engines, etc., we are constructing it out of collections of the general-purpose, cost-effective, high-performance building block that is typified by the desktop computer. We are developing the communications infrastructure, operating system support, programming environment, and tools that will enable construction of large scale systems out of complete commodity computers. It implements a combination of almost realistic-looking pseudo-physical behavior and idealized goal-oriented properties, which disambiguate the mapping of the 2D cursor motion on the display screen into an appropriate object motion in the 3D virtual world and determine valid and desirable final locations for the objects to be placed. www.cs.berkeley.edu /~culler/titan/progress96.html   (11114 words)

Europort Data Compression This, in general, conflicts with the Europort requirement of producing portable code, because the way to call C functions from Fortran depends very much on the operating system (more precisely on the loader). One requirement of EUROPORT is to write portable code that runs without modification on various types of parallel platforms. These local computers may be located at a different site, requiring tape or network transport, and they may use different definitions for binary data, rendering the use of binary file formats useless. rugmd4.chem.rug.nl /hoesel/xdrf.html   (482 words)
