摘要:
Methods and apparatus are provided for evaluating potential resource capacity in a system where there is elasticity and competition between a plurality of containers. A dynamic potential capacity is determined for at least one container in a plurality of containers competing for a total capacity of a larger container. A current utilization by each of the plurality of competing containers is obtained, and an equilibrium capacity is determined for each of the competing containers. The equilibrium capacity indicates a capacity that the corresponding container is entitled to. The dynamic potential capacity is determined based on the total capacity, a comparison of one or more of the current utilizations to one or more of the corresponding equilibrium capacities and a relative resource weight of each of the plurality of competing containers. The dynamic potential capacity is optionally recalculated when the set of plurality of containers is changed or after the assignment of each work element.

The invention provides methods for determining the susceptibility of cancer patients to developing adverse reactions if treated with a telomerase inhibitor drug by measurement of telomere length in appropriate cells of the patient prior to initiation of the telomerase inhibitor treatment.
摘要:
A system or computer usable program product for managing jobs scheduled for execution on a target system in which some jobs may spawn additional jobs scheduled for execution on the target system including intercepting jobs scheduled for execution in the target system, determining whether there is resource sufficiency in the target system for executing jobs, responsive to an affirmative determination of resource sufficiency, releasing previously intercepted jobs for execution in the target system, computing a limit of a number of jobs which can be concurrently scheduled by an external system to the target system, and transmitting the computed limit to the external system.

A solution is proposed for facilitating the selection of execution servers to be used in a scheduler for submitting the execution of jobs. Each job is defined by a corresponding descriptor. The descriptor specifies the execution servers to be used by the jobs in a formal way (through their properties); in addition, the descriptor may also include the definition of formal relationships to be satisfied by the execution server with other resources of the system (in turn defined in a formal way through their properties). A query is created according to the descriptor for selecting (concrete) execution servers having the desired properties and satisfying the desired relationships with the resources of the system. This query is then run on a central database, wherein all the concrete execution servers, resources and relationships are defined. In this way, it is possible to obtain a list of concrete execution servers eligible to execute the job in a single transaction.

A method for scheduling execution of a work unit in a data processing system, wherein the execution of the work unit involves the execution of at least one program, the method comprising: providing a first collection of pieces of information necessary to execute the work unit, said first collection of pieces of information being arranged in at least one pre-defined, re-usable program profile corresponding to the at least one program to be executed; receiving, in a request for scheduling execution of the work unit, a second collection of pieces of information necessary to execute the work unit; determining execution information for the execution of the work unit based on the first and second collections of pieces of information, and scheduling the execution of the work unit based on the determined execution information.
摘要:
A technique for monitoring computers connected to a hardware switch. The switch is used to selectively connect a single set of peripheral units to the central unit of a selected one of the computers. In the proposed solution, status information of each non-selected computer is transmitted from the corresponding central unit to the switch. For this purpose, it is preferably exploited a corresponding bi-directional input port—such as of the USE type. The switch routes the status information of the different non-selected computers to the central unit of the selected computer. The central unit of the selected computer aggregates the status information with its output information, and then transmits this aggregated information to the switch for its display on a monitor. For example, the output information is shown in a main area of the screen, while the status information is shown in a reserved strip on top of it.

摘要:
A method in a data processing system for managing jobs. A change to a job receiving that is un-instantiated. A reservation for the job is created. Instantiated jobs for an instance of the job are monitored corresponding to the reservation, and applying the change to the instance of the job responsive to identifying the instantiated job.
摘要:
A method (300) and a corresponding system for allocating resources in a hierarchical data processing system are proposed. The system includes a plurality of nodes that are arranged in a tree. Each leaf-node, or client, controls corresponding local resources, while each intermediate node, or domain manager, controls global resources that are visible to all its dependent nodes; the global resources defined on a root node, or master domain manager, are then visible to all the nodes of the system. Whenever a job, being submitted (306) on a generic client, requests a set of resources for its execution, the request is sent (309,318,327) through the tree to the master domain manager. The master domain manager allocates (339) the corresponding global resources as soon as they are all available; this event enables (345) its child node (in a path to the client) to perform the same operations, and so on down to the client itself. Once the client has allocated (357) the corresponding local resources, the execution of the job can be launched (360).
