The present invention employs a master node for each job to be scheduled and in turn the master node distributes job start information and executable tasks to a plurality of nodes configured in a hierarchical node tree of a multinode job scheduling system. The status of the various tasks executing at the leaf nodes and other nodes of the tree report status back up the same hierarchical tree structure used to start the job, not to a scheduling agent but rather to the master node which has been established by the scheduling agent as the focal point, not only for job starting, but also for the reporting of status information from the leaf and other nodes in the tree.

Dynamic allocation and partitioning of compute nodes in hierarchical job scheduling

A run-time customization capability extends functionality of a software application in a computer system. Through object-oriented design, an instance of a first class is instantiated. The first class (e.g., a derived class) has a same interface as a second class. The first and second classes enable respective first and second functionalities through respective first and second implementations of the same interface. The first implementation is dynamically loaded at run time. The dynamic loading can involve locating the first implementation, such as by using a locator to locate a module comprising the first implementation. A transfer vector usable in accessing the first implementation can be initialized to have an indication of a location of the first implementation. Programming code associated with the same interface can be compiled prior to compilation of programming code associated with the first implementation.

Run-time customization in object-oriented design

A complex task is managed by controlling the independent, cooperating components that make up the complex task. This control includes, for instance, pre-run dynamic validation of the components of the complex task; programmatic determination of the proper order to start, stop or delete one or more of the components; post-run automatic recovery from a terminated component; and/or automatic collection of information regarding the independent, cooperating components, such that the overall status of the complex task is obtained and understood. The control is provided through a centralized mechanism that enables easy configuration, control and monitoring of the independent, cooperating components of a complex task.

Managing independently executing computer tasks that are interrelated by

A system, method and program product for controlling multiple appearances of data on a display. A Controller is provided for receiving user instructions for data to be displayed, and for generating model management and view management instructions for controlling the appearance of data to be displayed. A Model is connected to the Controller for receiving model management instructions from the Controller, and for keeping track of changes to the appearance of data to be displayed. A ViewProxy is connected to said controller for receiving view management instructions, and connected to said Model for receiving model change notifications responsive to changes in the appearance of data to be displayed. Multiple Views are connected to the ViewProxy for receiving model change notifications. The ViewProxy determines to which Views the model change notifications are to be sent, and sends model change information to only those Views affected by said model changes. A windowing system displays only active Views, and switches between Views by making at least one View active and selected other Views inactive.
