A non-transitory computer-readable recording medium storing a program causing a processor to execute a process, the process includes detecting input of data into a memory to which data is inputted in sequence, the data being a processing object of first processing; allocating the first processing, of which a processing object is the data, with respect to any node in a communicable node group; determining whether or not the data is provided with tail information, the tail information indicating tail data of a series of data that are processing objects of the first processing, when detecting input of the data; and allocating second processing, of which a processing object is a processing result of the first processing that is executed with respect to each piece of data of the series of data, to any node of the node group when determining that the data is provided with the tail information.

A data processing control device performs a MapReduce process. When the data processing control device assigns input data to first Reduce tasks and a second Reduce task performed by using a result of Map processes, the data processing control device assigns input data with smaller amount than any of amounts of the input data which is assigned to the first Reduce tasks to the second Reduce task. The data processing control device assigns the first Reduce tasks and the second Reduce task, to which input data is assigned, to a server that performs Reduce processes in the MapReduce process such that the second Reduce task is started after the assignment of all of the first Reduce tasks.

In a delay time measuring apparatus a sequence number, data length, and receiving time of a data packet transmitted from a source unit to a destination unit are stored in a storage section. In addition, an ACK number and receiving time of an ACK packet returned from the destination unit to the source unit are stored in the storage section. After that, a calculation section obtains an ACK packet an ACK number of which is equal to a value obtained by adding data length of a second data packet of two successive data packets transmitted without waiting for the ACK packet to a sequence number of the second data packet of the two successive data packets from the storage section. Then the calculation section calculates round trip time from receiving time of the second data packet of the two successive data packets and receiving time of the ACK packet obtained.

A computer-readable non-transitory recording medium storing therein an information managing program causing a computer to execute extracting from among events that have occurred at objects under management and having dependence relations, combinations of a first event that has occurred at a source-of-dependence object and a second event that has occurred at a dependent object dependent on the source-of-dependence object; judging for each extracted combination, whether a dependence relation exists between the first event and the second event, by using the difference between the time of occurrence of the first event and that of the second event; determining from among the events and based on a judgment result obtained at the judging, an event that has occurred at an object that is a source-of-dependence object but not a dependent object, to be an event to be stored; and storing to a database, information related to the event to be stored.

Information managing computer product, apparatus, and method

Disclosed are a computer-readable recording medium which records communication programs, communication method and communication apparatus capable of easily performing selection and execution of communication units according to communication units of communication partners. A profile management unit manages specific information including a combination of device type information and user identification information in each communication unit, and user IDs associated with the combined information. An application controller, when a session using any one of communication units is established between users, refers to specific information and associates user IDs with the combined information in the communication unit. A collection unit collects presence information where state information indicating whether communication units are available is associated with the combined information in each communication unit. A presence management unit, when a user ID is specified, refers to presence information and reports presence information to client terminals of users where the session is established.

Computer-readable recording medium recording communication programs, communication method and communication apparatus

An alarm masking system is provided which is capable of implementing alarm priority processing or alarm inhibit processing in ATM transmission equipment. In ATM transmission equipment, a received virtual path or virtual channel is switched by means of a switching unit and then sent to an interface unit. In doing this, if a higher priority alarm is detected or received at a reception side interface unit, an intra-office tag is added to the alarm cell and then it is output, so that by detecting this intra-office tag it is possible to inhibit generation of lower priority alarms in response to the higher order alarm.
