摘要： A prefetch processing apparatus includes a central-processing-unit monitor unit that monitors processing states of the central processing unit in association with time elapsed from start time of executing a program. A cache-miss-data address obtaining unit obtains cache-miss-data addresses in association with the time elapsed from the start time of executing the program, and a cycle determining unit determines a cycle of time required for executing the program. An identifying unit identifies a prefetch position in a cycle in which a prefetch-target address is to be prefetched by associating the cycle determined by the cycle determining unit with the cache-miss data addresses obtained by the cache-miss-data address obtaining unit. The prefetch-target address is an address of data on which prefetch processing is to be performed.

摘要： The execution status of pipeline processing is highly visualized by appropriately displaying processes forming loops in a simplified manner. A loop-information storage unit stores loop-defining information specifying the address of an instruction that causes a pipeline process forming a loop. An operation-information storage unit stores operation information that includes the address of an instruction input into a pipeline and information indicating the execution status of a pipeline process caused by the instruction. A loop determination unit determines whether each pipeline process indicated by the operation information forms a loop by referring to the loop-defining information. An output unit outputs visualization information indicating, in a visually comprehensible manner, the execution status of a pipeline process that has been determined to form a loop for a predetermined number of executions of the loop and the execution status of a pipeline process that has been determined to form no loop.

摘要： A recording medium which is readable by a computer stores a performance analyzing program for searching for a node that is peculiar in performance in a cluster system, as well as unknown problems. The performance analyzing program enables the computer to function as various functional units. A performance data analyzing unit collects performance data of nodes which make up the cluster system from performance data storage unit for storing a plurality of types of performance data of the nodes, and analyzes performance values of the nodes based on the collected performance data. A classifying unit classifies the nodes into a plurality of groups by statistically processing the performance data collected by the performance data analyzing unit according to a predetermined classifying condition. A group performance value calculating unit statistically processes the performance data of the respective groups based on the performance data of the nodes classified into the groups, and calculates statistic values for the respective types of the performance data of the groups. A performance data comparison display unit displays the statistic values of the groups for the respective types of the performance data for comparison between the groups.
