-
- HP Task Broker: A Tool for Distributing Computational Tasks
- With HP Task Broker, the user can:
- o Distribute computational tasks among heterogeneous UNIX-based computer
- systems.
- o Benefit from greatly improved productivity, access to more compute
- power when needed, and reduced hardware costs.
- o Perform computational distribution without any changes to the
- application itself.
- o "Load Balance" a group of computer systems by transparently finding
- the most available server for a computational task.
- o Transparently target specific servers most appropriate for a
- specialized task.
- o Form a "computational cluster", which can replace a far more expensive
- mainframe or supercomputer, and provide increased availability,
- scalability, and reduced costs.
- o Create a "heterogeneous cluster", allowing networks of machines from
- multiple vendors to interoperate in a completely transparent fashion.
-
- Task Broker Features
- Task Broker offers a number of features that provide more efficient
- access to compute resources across a network:
- o Application code does not have to be recompiled to be run by Task
- Broker.
- o Task Broker automatically sends results back to a user-specified file
- on the user's computer. Mail messages can be sent to notify the user
- the job is complete.
- o Servers and clients are added to a network equipped with Task Broker
- simply by hooking the machine to a LAN, updating the central Task
- Broker configuration file to include the new client/server, and
- starting the Task Broker daemon.
- o Task Broker provides an accounting of services used on a given server.
- o The number of applications running on a computer at any one time can
- be limited. This prevents degradation of server performance.
- o Users can control the use of their computer as a server. For example,
- users can specify that their workstations be accessed only at night.
-
- Task Broker Benefits
- In situations where jobs need to be executed on remote computers, Task
- Broker offers more flexibility and power than existing network
- utilities, such as those for remote copying of files (ftp) or remote
- shell execution (remsh). Moreover, Task Broker enables you to define
- what services are to be provided on which computers, how and when each
- service will be provided, as well as who can access these services.
- Task Broker has the following user benefits:
- o More efficient access to compute resources (i.e., load balancing) -
- Task Broker assigns jobs to the server node, whether a specialized
- server platform or unused workstation - whichever is most appropriate
- at the time. For example, a high-end compute server is obviously
- better for solving compute-intensive simulations such as finite
- element analysis. However, if this server is overloaded and a
- workstation that could do an adequate job is left idle, the overall
- productivity of the computer environment suffers.
- o Improved productivity and products - By allowing multiple compute jobs
- to run in parallel and/or on faster systems, performance is
- dramatically improved. Users may use the time saved to run more jobs
- in a given time period in order to improve product design or shorten
- development time.
- o Greater flexibility and ease of accessing multiple servers - The fact
- that all users get access to each other's idle cycles makes for a
- winning proposition for the entire work group.
- o Access to heterogeneous computers - You can build a cooperative
- computing environment. For example, a task submitted from an HP 9000
- Series 700 workstation may be serviced by a Series 300 or 400
- workstation, or vice versa.
-
- Features of the New Release
- o A graphic user interface (GUI) has been added, greatly improving the
- product's ease-of-use. The GUI provides a visual interface to most of
- the Task Broker command set and configuration information, simplifying
- Task Broker administration. In addition, task status monitoring and
- control is provided for the end user.
- o Centralized configuration management has been added to the new
- release. This feature allows the entire Task Broker installation to be
- initialized using a single group configuration, and to be administered
- from any single machine site.
- o An integrated forms-based configuration editor provides for easier and
- more robust administration of Task Broker information. The
- configuration syntax is simpler and checking is done during the
- editing session.
- o An online, context sensitive help sub-system, utilizing HP's CACHE
- CREEK product, contributes to Task Broker's overall ease-of-use by
- providing usage information when it's needed.
