摘要:
A method (300) for delivering monitoring data is proposed. The monitoring data is collected on a central server from selected managed computers, in order to be provided to multiple clients (in response to periodic requests). In the method of the invention, for each managed computer the central server estimates (336;351-354) an expected duration of a next collection of the monitoring data (according to the duration of one or more preceding collections). A trigger delay of the next collection is then calculated by subtracting (366) a time advance to the expected time of the next request (defined by the corresponding period); the time advance is based (339-348;357;363) on the expected duration of the next collection, suitably incremented by a safety margin (so as to prevent receiving the next request before the corresponding collection has completed). The monitoring data is then pre-fetched (315-324) from the managed computer when the trigger delay expires.

A workload scheduler detects a long-running job when its duration exceeds a threshold value calculated by applying a multiplication factor to an estimated duration of the job. An operator inputs two extreme values of the multiplication factor, which consist of an upper level for the short-duration jobs and a lower level for the long-duration jobs. An algorithm then calculates the appropriate multiplication factor for any particular job, giving much more weight to the upper level when the estimated duration is small, but which gradually swings the levels to give more importance to the lower level when the estimated duration is long.
摘要:
A collaborative workload management system comprises a workload scheduler cooperable with a schedule to submit work units for processing on a computer system according to the schedule; and a workload manager adapted to monitor work units being submitted for processing and to allocate resources for processing respective work units on the computer system according to a respective service class of the work units. The workload scheduler further provides the workload manager with work unit attributes as each work unit is submitted for processing, the attributes comprising at least one indicator of the resources typically required by the work unit. The workload manager retrieves the work unit attributes and tunes the resources required to process the work unit according to the work unit's attributes without exceeding the resources allowed for processing work units of the work unit's service class.

A solution (300) for metering usage of software products on a data processing system is proposed. In this context, it is often necessary to known a processing power of each computer wherein a generic software product ran (for example, for licensing accounting based on differentiated charging rates). In the proposed solution, the processing power is estimated dynamically on the computer directly. For this purpose, a (single-threaded) benchmark program written in a low-level language is executed (308-322), such as at the startup or periodically. In this way, dividing (324) the measured execution time of the benchmark program by the known number of its instructions it is possible to determine an execution rate of a single microprocessor of the computer. This value multiplied (326) by the detected (306; 332) number of available microprocessors provides an accurate estimate of the processing power of the computer. The desired result is achieved without requiring any knowledge of the physical details of the computer; this is particularly advantageous when the computer consists of a logical guest machine implemented on a physical host machine.

A method of displaying electronic documents on a vehicle display screen is described. The vehicle includes a display screen embedded in a window of the vehicle in a manner visible from outside the vehicle. The method includes storing the digital certificate in a memory unit of the control module. The method includes displaying information on the display screen by retrieving the digital certificate. Also, upon validating the digital certificate, the information associated with the digital certificate is displayed on the display screen, wherein the information includes an electronic document that indicates at least one of compliance with a local law, valid insurance, validation of payment of taxes associated with the vehicle, and a parking receipt for parking the vehicle, wherein the display screen comprises at least one button, manipulable by a user outside of said vehicle, to select a display mode of said display screen.
摘要:
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.

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 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.
摘要:
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 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.
