20150121103 | INFORMATION PROCESSING APPARATUS AND LOAD CONTROL METHOD - An information processing apparatus includes a processor that is capable of switching a performance level to one of a plurality of performance levels with different power consumption, and a storage unit that stores a program for controlling the performance level of the processor. The processor executing the program detects the periodicity of load variation of the information processing apparatus, and changes, according to the periodicity of the load variation, a determination interval for determining whether to switch the performance level of the processor. | 04-30-2015 |
20140068623 | INFORMATION PROCESSING APPARATUS, COMPUTER PROGRAM, AND METHOD FOR CONTROLLING EXECUTION OF JOBS - An information processing apparatus submits jobs for execution on a server. Jobs are classified into a plurality of groups, and these groups are ranked in ascending order of workload that the groups of jobs impose on the server. A processor in the information processing apparatus counts ongoing jobs that are currently executed on the server and belong to a specified number of top-ranked groups. The processor designates pending jobs that belong to other groups than the specified number of top-ranked groups and suspends submission of processing requests of the designated pending jobs to the server, when the number of ongoing jobs is greater than or equal to a threshold and when there are one or more pending jobs that belong to the specified number of top-ranked groups. | 03-06-2014 |
20140052841 | COMPUTER PROGRAM, METHOD, AND INFORMATION PROCESSING APPARATUS FOR ANALYZING PERFORMANCE OF COMPUTER SYSTEM - In an information processing apparatus, a comparing unit determines whether the response time of each transaction falls within an acceptable time range that is specified previously. For each time window, a first calculation unit calculates a load of processes executed in parallel by the servers in a specified tier, based on transaction data of individual transactions. Further, a second calculation unit calculates a total progress quantity in each time window, based on the transaction data of transactions whose respective response times are determined to fall within the acceptable time range. A determination unit determines a specific load value as a threshold at which the total progress quantity begins to decrease in spite of an increase of the load. | 02-20-2014 |
20130116976 | Method, computer program, and information processing apparatus for analyzing performance of computer system - In an information processing apparatus, a calculation unit retrieves data that indicates processing periods of processes executed in each time window constituting an analysis period. The calculation unit then calculates a total processing time for each time window by adding up processing times spent for execution of processes. The calculation unit also calculates a total progress quantity for each time window by adding up progress quantities of the processes. A determination unit determines, based on the total processing time and total progress quantity of each time window, a threshold of the total processing times at which the ratio of an increase of the total progress quantity to an increase of the total processing time is equal to or smaller than a predetermined value. A detection unit detects time windows whose total processing times are equal to or longer than the threshold. | 05-09-2013 |
