摘要:
A method for optimizing energy consumption in a data-processing system comprising a set of data-processing units is disclosed. In one embodiment, such a method includes indicating a set of data-processing jobs to be executed on a data-processing system during a production period. An ambient temperature expected for each data-processing unit during the production period is estimated. The method calculates an execution scheme for the data-processing jobs on the data-processing system. The execution scheme optimizes the energy consumed by the data-processing system to execute the data-processing jobs based on the ambient temperature of the data-processing units. The method then executes the data-processing jobs on the data processing system according to the execution scheme. A corresponding apparatus and computer program product are also disclosed.

A solution (400) for scheduling execution of jobs is proposed. The submission of the jobs is generally controlled according to a production plan (406), which specifies a required finish time of critical jobs. In the proposed solution, a current progress of each critical job is monitored (427-430)—such as comparing a (measured) number of processor cycles dedicated to the critical job with an estimated total number thereof (required to complete the critical job, as inferred from previous executions thereof). At the same time, an expected progress of each critical job is estimated (433)—such as by the ratio between a time elapsed from an actual start time of the critical job and an allowable duration thereof (from the actual start time to the required finish time). The current progress of each critical job is then compared with its expected progress, so as to identify (436) the critical jobs that are late in their execution. Additional execution resources can then be assigned to each late critical job only when it is necessary to bring back the critical job on schedule.

A method, system and computer product for accessing, by means of a telephone, a database containing data arranged in at least one table including a plurality of table entries, each table entry including a plurality of information elements. The invention retrieves identifiers of the information elements from the table. Each of the retrieved identifiers of the information elements are associated with a choice key, wherein the choice keys are adapted to be input by a user through a telephone. The invention presents, through the telephone, the identifiers of the information elements together with the respective choice keys to a user. Once a choice key input by the user is received through the telephone, the invention retrieves data from the table using the input choice key, wherein said retrieved data includes the content of the information element in at least one table entry whose identifier corresponds to the input choice key. The retrieved data is presented to the user through the telephone.

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.

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.
