摘要:
A scheduling method and system. The method includes receiving, by a computing system, job related data associated with a plurality of jobs to be executed by said computing system, time constraint data, and maximum time shift values associated with the time constraint data. The computing system determines that a start time for execution of a first job of the plurality of jobs should be rescheduled. The computing system receives workload statistics. The computing system determines based on the workload statistics, a first start time for the first job. The computing system compares the time constraint data with the first start time to determine if the first start time is in conflict with the time constraint data. The computing system stores the first start time.

A mechanism is provided for rescheduling jobs for execution by a computing system. The computing system receives job related data associated with a plurality of jobs to be executed by the computing system, time constraint data, and maximum time shift values associated with the time constraint data. The computing system determines that a start time for execution of a first job of the plurality of jobs should be rescheduled. The computing system receives workload statistics. The computing system determines based on the workload statistics, a first start time for the first job. The computing system compares the time constraint data with the first start time to determine if the first start time is in conflict with the time constraint data. The computing system stores the first start time.
摘要:
A solution for scheduling execution of jobs in a data processing system is disclosed. One method for implementing such a solution may start by providing a scheduling structure for scheduling the execution of jobs. Such a scheduling structure may include a workflow plan defining a flow of execution for planned jobs and/or a workflow model defining static policies for execution of modeled jobs. A set of rules for updating the scheduling structure is provided. The method may continue by updating the scheduling structure according to the rules, such as by adding or removing jobs for rules evaluated to be true. The execution of the jobs may then be scheduled according to the updated scheduling structure. A corresponding system and computer program product are also disclosed.
摘要:
A scheduler is provided, which takes into account the location of the data to be accessed by a set of jobs. Once all the dependencies and the scheduling constraints of the plan are respected, the scheduler optimizes the order of the remaining jobs to be run, also considering the location of the data to be accessed. Several jobs needing an access to a dataset on a specific disk may be grouped together so that the grouped jobs are executed in succession, e.g., to prevent activating and deactivating the storage device several times, thus improving the power consumption and also avoiding input output performances degradation.

Modeling non-functional requirements (NFRs) in a computer programming environment. In one aspect, this further comprises: identifying use case (UC) artifacts having one or more NFRs; retrieving the one or more NFRs and any data associated therewith; analysing the associated data to define a test case therefor; retrieving a UC realization from a model to determine one or more possible program flows; and testing each possible program flow to select the test case which verifies the use case required, thereby modeling the NFR.
摘要:
A solution for managing a software image being stored in a plurality of physical blocks of a storage system comprises monitoring each access to the physical blocks, calculating a predicted sequence of access to the physical blocks according to the monitored accesses, and reorganizing the physical blocks according to the predicted sequence. The monitoring may be performed as the physical blocks are accessed during the booting of virtual images on the software image.

Embodiments monitor the participation of remote users to conference calls even when they are connected through simple telephone, i.e. without multimedia (or Internet) connection. In particular, an embodiment enables callers to monitor an up to date list of participants without the need of using a dedicated phone or connecting through a PC and a dedicated line to a central Conference Call system. This can be highly useful in case of travelling users who are expected to join the call from different places. Embodiments may not need a complex network infrastructure or network protocol change, since the information about the participant list can be transmitted over the normal phone line using a predetermined set of signals (e.g. an acoustic signal). Both the Conference Call server and the peripheral devices may refer to the same set of signals. Embodiments may be transparent to those users who do not wish to (or cannot) use the new functionality.

A method and system for managing power consumption by electrical appliances, is provided. One implementation involves obtaining power consumption information for a use cycle of a each of multiple appliances; and automatically scheduling a time slot for an operation cycle of a selected appliance as a function of power consumption by appliance cycles scheduled in that time slot, such that an upper limit of power consumption is not exceeded by the collective power consumption for scheduled appliance cycles in the time slot.

A mechanism for reducing electronic mail (email) sizes by using a local archive of email components is provided. The mechanism receives the email file, the email file specifying a sender identifier of a sender of the email file, a recipient identifier of a recipient of the email file, and common component information for a common component included in the email file, the common component being a component of the email file that is common amongst a plurality of email files sent from the sender. The mechanism identifies the common component of the email file and determines whether to remove the common component from the email file before forwarding the email file to the recipient based on at least the sender identifier. Based on the determination, the common component is either removed or kept in the email file that is subsequently transmitted to the recipient computer.
摘要:
A method and system for dynamically sharing performance information among multiple computing nodes. One implementation involves dynamically obtaining performance information from deployments of an information technology (IT) product/solution at said computing nodes, and transmitting the obtained performance information to a server over a communication network for storing the obtained performance information in a knowledge database. The server operates to dynamically determine new configuration information based on the information in the database, store the new configuration in the database, and provide the new configuration information to said deployments by transmitting the new configuration information over the network.
