Abstract: Provided is a complier which optimizes parallel processing. The complier records the number of execution cores, which is the number of processor cores that execute a target program. First, the compiler detects a dominant path, which is a candidate of an execution path to be consecutively executed by a single processor core, from a target program. Subsequently, the compiler selects dominant paths with the number not larger than the number of execution cores, and generates clusters of tasks to be executed by a multi-core processor in parallel or consecutively. After that, the compiler computes an execution time for which each of the generated clusters is executed by the processor cores with the number equal to one or each of a plurality natural numbers selected from the natural numbers not larger than the number of execution cores. Then, the compiler selects the number of processor cores to be assigned for execution of each of the clusters based on the computed execution time.

Abstract: Provides methods, apparatus and systems for message request response server and processor. A server apparatus including: a request processing unit for performing processing for a first processing request message received, and creating a first processing response message; a cache unit for caching the first processing response message in association with a first key created based on the first processing request message; a message analysis unit for analyzing the second processing request message received; a key creation unit for creating a second key based on the analysis result; and a cache management unit for returning the cached first processing response message when the second key coincides with the first key, and when the second key does not coincide with the first key, notifying the result of the analysis, allowing the request processing unit to perform processing based on the analysis result, and returning the second processing response message created.
