A distributed device management system specifies a device capable of supplying request data used for providing a service, from among a plurality of devices connected to a network. Device management function units are disposed so as to be geographically distributed and manage the states of the devices located in deployed areas. A device specifying function unit has a device inquiry cache in which a response log including the type of data which was previously required for the service and an identifier of the device management function unit that manages the device which was capable of supplying the data is recorded. In a case where this request data coincides with the type of data included in the response log, an inquiry is transmitted to the device management function unit associated with the request data in the response log.

Distributed device management system and distributed device management method

An offloading server includes: a data transfer designation section configured to analyze reference relationships of variables used in loop statements in an application and designate, for data that can be transferred outside a loop, a data transfer using an explicit directive that explicitly specifies a data transfer outside the loop; a parallel processing designation section configured to identify loop statements in the application and specify a directive specifying application of parallel processing by an accelerator and perform compilation for each of the loop statements; and a parallel processing pattern creation section configured to exclude loop statements causing a compilation error from loop statements to be offloaded and create a plurality of parallel processing patterns each of which specifies whether to perform parallel processing for each of the loop statements not causing a compilation error.

A device identification device () includes: a device feature value extractor (--) to routinely extract one or more device feature values of an unknown device; a model identifier () to identify a model of the unknown device; a change pattern generator () to generate one or more change patterns of the extracted one or more device feature values; and a device similarity calculator () to compare each of the generated one or more change patterns with each of change patterns of known devices, to calculate a device similarity therebetween, and identify the unknown device, when the maximum value of the calculated device similarities is equal to or greater than a first threshold, as the known device indicating the maximum value.

An offload server includes: a parallel processing designation section configured to identify repeat statements in an application and specify a directive specifying application of parallel processing by an accelerator and perform compilation for each of the repeat statements; a parallel processing pattern creation section configured to create parallel processing patterns each of which specifies whether to perform parallel processing for repeat statements not causing a compilation error; a performance measurement section configured to compile the application with a parallel processing pattern, deploy the compiled application to a verification machine, and perform processing for a measurement of a performance of the application; and an executable file creation section configured to compile a parallel processing pattern with the highest processing performance to create an executable file.
