Abstract: A configuration general management server includes a storage device and a processing device. The storage device stores IT infrastructure configuration information indicating physical connections and logical connections and arrangement information of resources constituting the IT infrastructure, and application dependency information indicating dependency of an application being executed by a host on the IT infrastructure.

Abstract: A workload control device stores: workload management information for managing an execution schedule and power consumption of the workloads constituting the pipeline; and reduced power consumption management information for managing information about power consumption that needs to be reduced from scheduled power consumption and indicative of a reduction period and amount of power consumption. Based on the workload management information and the reduced power consumption management information, the workload control device: determines a priority of a workload to be determined whether to be interrupted; provides a workload scheduled to be terminated by the start of the reduction period with a priority higher than that of a workload scheduled to be terminated after the start of the reduction period; and determines an execution method of the workloads in the order of the priority until the total of the power consumption of the determined workloads reach the reduced amount in the pipeline.

Abstract: To reduce a power surplus of fluctuating renewable energy. Data center candidate management information indicates a characteristic of renewable energy supplied to each data center candidate. Application program type candidate management information indicates a characteristic of each application program type candidate. The system determines, with reference to the data center candidate management information and the application program type candidate management information, a plurality of combinations each including one or more data center candidates and one or more application program type candidates, determines a score of each combination based on a characteristic of renewable energy supplied to each of the one or more data center candidates and a characteristic of each of the one or more application program type candidates, and selects, based on the score, a combination to be presented.

Abstract: A data center (DC) user device manages user power consumption in a time unit, and stores the user power consumption in a power consumption table. A DC provider device manages provider power consumption in a time unit and stores the provider power consumption in the power consumption table. A power retailer device measures provider power consumption for a certain period, and determines retailer power consumption when a measurement value of the provider power consumption is equal to a total value of all user power consumptions.

Abstract: The invention achieves an increase in speed and optimization of a cooperative operation plan creation work between a data center operator and a user. In an operation plan creation method in a data center, an operation plan server calculates a handling cost to handle a given consumption pattern of a DC user when an operation plan of a created workload (WL) is to be created or changed, and creates an operation plan optimization equation for maximizing or minimizing an index such as a cost including the handling cost. At this time, a solution of the operation plan optimization equation is obtained such that a consumption pattern obtained by changing a consumption pattern in a past response history of the user according to a certain rule is available at a handling cost to handle the changed consumption pattern, thereby creating an operation plan draft for the consumption pattern of the user and a device held by a data center operator.

Abstract: A process for producing a resin dispersion characterized in that an ethylenically unsaturated monomer capable of forming a polymer insoluble in an aqueous medium is polymerized in a solution formed by dissolving in said aqueous medium a water-soluble polymer derived from(1) 10-90% by weight of a hydroxyalkyl (meth-)acrylate expressed by the following general formula ##STR1## wherein R is a hydrogen atom or a methyl group, and l is an integer of 2, 3 or 4,(2) 10-90% by weight of a polyalkyleneglycol mono (meth-)acrylate expressed by the following general formula ##STR2## wherein R is a hydrogen atom or a methyl group, m is an integer of 2 or 3, and n is an integer of 2 to 20, and(3) 0-30% by weight of another ethylenically unsaturated monomer.
