摘要:
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:
In an embodiment for deploying a new virtual appliance (225) on a data processing center (100) structure information of the new virtual appliance is determined (509-521). The structure information of the new virtual appliance includes an indication of the new virtual machines and an indication of the new software programs of each new virtual machine. Configuration information indicative of a current configuration of the data processing center is retrieved (527). License condition information indicative of license conditions applicable to the data processing center is also retrieved (530-533). A deployment scheme of the virtual appliance on the data processing center is then determined (539,548). The determination of the deployment scheme is performed by optimizing a cost function based on the license condition information, the configuration information and the structure information, and the new virtual appliance may be deployed (551) according to the deployment scheme.

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.
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.
摘要:
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.
摘要:
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.
