Abstract: Provided is power consumption estimation means that can accurately estimate the power consumption of diverse applications. A power consumption estimating device includes a metadata DB that stores past application metadata related to each of past applications, a power consumption DB including power consumption information representing the power consumption of the past applications, and a power consumption estimating section that estimates the power consumption of an estimation target application. The power consumption estimating section extracts target application metadata from an application manifest related to the estimation target application, calculates the degree of similarity of the target application metadata to the past application metadata, extracts, from the power consumption DB, first power consumption information corresponding to a similar application having a degree of similarity which satisfies a predetermined degree-of-similarity criterion, and outputs the first power consumption information as a first power consumption estimation result.

Abstract: A log message grouping apparatus calculates a coincidence degree evaluation value E1 representing the degree of coincidence between minority words, which are relatively low occurrence frequency words, out of the words that form a log message and minority words in another log message. The log message grouping apparatus further calculates an occurrence degree evaluation value E2 representing the degree of occurrence of the combination of a classification value of a log message and the classification value of a past log message on the basis of the occurrence frequency of the combination of the classification values and calculates an association degree evaluation value E3 representing the degree of association between the log message and the past log message on the basis of the coincidence degree evaluation value E1 and the occurrence degree evaluation value E2.

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: 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. The operation plan server confirms, to a WL execution management server, whether the operation plan draft can be executed, and instructs the WL execution management server to execute the operation plan draft.
