Fork (operating system) - Wikipedia, the free encyclopedia A fork, when applied to computing is when a process creates a copy of itself, which then acts as a "child" of the original process, now called the "parent". More generally, a fork in a multithreading environment means that a thread of execution is duplicated. Forking is an important part of Unix, critical to the support of its design philosophy, which encourages the development of filters. en.wikipedia.org /wiki/Fork_(computing)   (566 words)

Bin's On-Line Dictionary Fork beam (Shipbuilding), a half beam to support a deck, where hatchways occur. The forks of a river or a road, the branches into which it divides, or which come together to form it; the place where separation or union takes place. A fork followed by an exec can be used to start a different process but this can be inefficient and some later Unix variants provide vfork as an alternative mechanism for this. language.bin.org /ref/dict/?t=fork   (421 words)

Computer - Wikipedia, the free encyclopedia Therefore, computers with capabilities ranging from those of a personal digital assistant to a supercomputer may all perform the same tasks, as long as time and memory capacity are not considerations. Computer operating systems and applications were modified to include the ability to define and access the resources of other computers on the network, such as peripheral devices, stored information, and the like, as extensions of the resources of an individual computer. Computer science is a traditional name of the academic study of the processes related to computers and computation, such as developing efficient algorithms to perform specific class of tasks. en.wikipedia.org /wiki/Computer   (5113 words)

Fork   (Site not responding. Last check: 2007-10-12) Fork is a programming language for the PRAM model; it has been implemented for the SB-PRAM. Fork is based on ANSI C with extensions for the management of shared and private address subspaces and variables, and for static and dynamic nesting parallelism by processor group splitting constructs. Graphical trace file visualization of Fork program traces is obtained by adding four tracing routine calls to the program, compiling/linking it with the -T option, running the instrumented version, and submitting the generated trace file to the trv tool (here is the man page of trv in groff and in postscript format). www.ida.liu.se /~chrke/fork95.html   (2146 words)

Fork bomb - Wikipedia, the free encyclopedia Fork bombs can be considered as a special type of wabbit (a program that self-replicates without using hosts or network functionality). Once a successful fork bomb has been activated in a system it may not be possible to resume normal operation without rebooting, as the only solution to a fork bomb is to destroy all instances of it. Another solution involves the detection of fork bombs by the kernel, which is not widely practiced although has been implemented in the form of a kernel module for the Linux kernel [1]. en.wikipedia.org /wiki/Fork_bomb   (527 words)

8.3 Parallel Computing Software Forking, however, is not appropriate for parallel computing. Fortran is one of the oldest computer languages and has many reliable and efficient numerical libraries and compilers. After the sum has been computed and printed, the master task informs the PVM daemon that it is withdrawing from the virtual machine. www.quantlet.com /mdstat/scripts/csa/html/node66.html   (3551 words)

14 Parallel   (Site not responding. Last check: 2007-10-12) The value returned by fork to the parent is known as the process id (pid) of the child. Synchronization is required in the sense that the result of a given sub-expression can't be computed before the principal components have been computed. The speedup of a parallel computation is the ratio of the sequential execution time to the parallel execution time for the same problem. www.cs.hmc.edu /claremont/keller/webBook/ch14/index.html   (5455 words)

The UNIX Forums - Fork The concept is similar in UNIX processes, however the fork occurs with the logic flow of the program and processes. So, forking is just something that occurs to a process in its "path of execution". The main difference between forking processes and your fork as your walk down the road is that you can't physically walk down two paths. www.unix.com /showthread.php?t=515   (425 words)

Phillip Rhodes' Weblog As you may be aware, the founders / owners of the Nessus project - an open-source vulnerability scanning tool - have decided not to release the new version under the GPL. It seems that quite a few people in the F/OSS world feel that it's unethical to fork the project since one of the primary reasons the developers cited for closing the source, was lack of input from the community at large. Probably the biggest issue the forkers will face is, can they get enough support and community involvement to maintain the fork and keep it updated to an acceptable level. jroller.com /page/mindcrime?entry=brits_fork_nessus   (324 words)

[FoRK] [wearables] On-body computing outsells desktops + laptops 3:1 (sales stats) (fwd from thad@cc.gatech.edu) Since 2003, processors for on-body computers have outsold desktop and laptop processors combined. Basically, as Brad Rhodes predicted, the road to wearables seems to be through the mobile phone. Even more interesting, by my calculations, Nokia is now the #1 consumer computer manufacturer in the world (55M handsets vs 28M desktop+laptop computers by HP-17% of the market). www.xent.com /pipermail/fork/Week-of-Mon-20040712/030883.html   (655 words)

TAU_REGISTER_FORK It takes two parameters, the first is the node id of the child process (typically the process id returned by the fork call or any 0..N-1 range integer). The second parameter specifies whether the performance data for the child process should be derived from the parent at the time of fork ( If the process id is used as the node id, before any analysis is done, all profile files should be converted to contiguous node numbers (from 0..N-1). www.cs.uoregon.edu /research/tau/docs/tauapi/rn01re25.html   (198 words)

AtheOS Fork Breathes Life to BeOS - OSNews.com Bill Hayden did the obvious: He forked AtheOS (which is technically similar to BeOS) and used its app_server and Interface Kit (without the use of X11) and rest of its kits on top of the 2.4.x Linux kernel. While the AtheOS kernel has some very nice features, by being modular, semi-microkernel, with good preemptive/multithreading support etc., it lacks a solid VM and swap support and of course, it lacks a good driver support, things that the Linux kernel provides. Bill Hayden accounced his fork on the AtheOS mailing list and made known that the "Atheos API has been merged with the BeOS API, there is PowerPC support, gcc 3.0.X compatiblity and OpenTracker/Deskbar as the desktop manager". www.osnews.com /story.php?news_id=852   (351 words)

Computing.Net - function fork() to Windows NT I need to use the function fork() in the windows nt plataform, so could you give me some tips how can do it. I know that fork create child processes,and that to make this in Win NT can use the library of Unix that has the function fork or to rewrite the code whit CreateProcess or CreateThread, but I know neither which library fork()uses nor if I have to create process or thread. Well if you use a NT library with the function fork most likely it will use the function CreateProcess anyways in the library so you might as well just use the WIN32 functions. www.computing.net /programming/wwwboard/forum/60.html   (414 words)
