Overview

Work queue route is a process to create large client applications. By using the Queue Workplace library, you create a special vocational program that defines and provides many small tasks. Each work is divided into a remote system that processes and returns the results. As the results are created, the Lord can create many tasks. It is not uncommon to write programs that pay millions of jobs to thousands of remote employees.

Each employee system is a generic implementation that can be combined with the computer and existing methodologies, making it easy to download the Employment Security application to operate the machines that you can already access. If you use a university or a commercial line provider, your claims work may be executed there.

Road work is a manufacturing method used to create high-tech science, bioinformatics, data mining and more. It can also be used to operate Makeflow machines. To see some of the current Work Queue applications, search for the actual page.

 




Master stage: Master Master / staff plan

Work en route is a way to create large client applications that offer thousands of tools collected from equipment, clouds and recorders. Job Papers applications are written in C, Perl or Python using a simple API that allows users to describe jobs, forward the queue and wait to finish them. The operations are carried out using a standard operating system that can operate on a machine. Each employee calls home in the process of weight loss, prepares data transfer and performs tasks. The system deals with many types of failures, allowing the adaptation of sophisticated applications.

The route work was used to document applications from many sites in the workplace to tens of thousands of supercomputers. Examples include Lobster, NanoReactors, ForceBalance, heavy creams, SANDA adhesives, Makeflow workpiece and All-Pairs and Wavefront substances. The system is easy to use and is used to introduce computer-integrated computing, cloud computing and the Internet at the University of Notre Dame, the University of Arizona and the University of Wisconsin - Eau Claire.

Installing Work Queue

Work Queue is part of the Cooperating Computing Tools. The CCTools package can be downloaded from this web page. Follow the installation instructions to setup CCTools required for running Work Queue. The documentation for the full set of features of the Work Queue API can be viewed from either within the CCTools package.

Building a Work Queue Application

Let's begin by running a simple but complete example of a Work Queue application. After trying it out, we will then show how to write a Work Queue application from scratch.
We assume that you have downloaded and installed the cctools package in your home directory under $HOME/cctools. Next, download the example file for the language of your choice:
  • C
  • Python
  • Perl

 
Advanced Topics


Highly qualified types are available for programs with extraordinary needs or overweight. Each device is described here, and more details of the API Job Location can be obtained.

Presentation presentation.

If you have a large number of tasks, you may not be able to send all the activities and then wait for all of them. Instead, send a small amount of work and then look forward and forward to get a permanent number in the queue. work_queue_hungry will tell you if it is necessary to release it.

Display of documentation materials

If you want to see the output of the product when it is released, add the indicator job WORK_QUEUE_WATCH to work_queue_specify_file. This will lead the staff to send you a copy of the file regularly. This is beneficial for a program developed in the basic aspects or the management of development as part of its production.

 Change asynchronously

If you have a balanced balance or a calculator, this can help improve CPU usage and reduce the transfer of data related to runtime. Asynchronously, this function captures data production and production personnel and when they are working when they perform tasks. See job_queue_specify_asynchrony.

Long-range

A large calculator can often reduce aggression. If you have a large number of small businesses that take little time, then an open mind can help. The Alert Attention Index presents statistics on executive functions and actively participates in work that is against the census. See work_queue_activate_fast_abort.

 Emergency information

For many jobs or staff, it may be inappropriate to create internal files for everyone. If the teacher already has the necessary memory information, you can directly forward data from long-range jobs to work_queue_task_specify_buffer.

Strategic Mediation

If you have used many operating systems (such as Linux, Cygwin, Solaris) and / or buildings (such as i686, x86_64) and have special files on each of these systems, this will help. The types of $ OS and $ ARCH are available for use in the details of the data files. Work Queuing will automatically resolve these words for the operating system and design of each connected staff and will transfer the file name associated with the resolved file.
