Model generation apparatus, information processing apparatus, model generation method, and computer program product

A model generation method for generating a decision model for deciding a memory control method based on the operation information used by an information processing apparatus that accesses a plurality of different types of main storage memories, the model generation method performs:

• acquiring time-series data of operation information that is obtainable in a case where the information processing apparatus is operated;
• dividing the time-series data of the operation information in a time direction to generate a plurality of segments;
• allocating any one memory control method of a plurality of memory control methods to each of the plurality of segments;
• estimating, for each of the plurality of segments, execution performance of memory access that is obtainable in a case where the information processing apparatus executes processing of a corresponding segment by an allocated memory control method;
• selecting a plurality of training segments in which the estimated execution performance satisfies a predefined condition, from among the plurality of segments;
• and
• generating the decision model based on the selected plurality of training segments and the allocated memory control methods corresponding to the selected plurality of training segments.

A computer program product having a computer readable medium including a program for causing an information processing apparatus to generate a decision model for deciding a memory control method based on the operation information used by an information processing apparatus that accesses a plurality of different types of main storage memories, the program causing the information processing apparatus to perform:

• acquiring time-series data of operation information that is obtainable in a case where the information processing apparatus is operated;
• dividing the time-series data of the operation information in a time direction to generate a plurality of segments;
