Method, information processing apparatus, and medium

An information processing apparatus comprising:

• a memory;
• and
• a processor coupled to the memory and configured to
• calculate a percentage of an instruction belonging to a certain instruction type among instruction types included in a block, the block being one of a plurality of blocks partitioned from a program;
• extract an execution address and a number of execution instructions from an arithmetic processing unit that executes the program and performs sampling of the execution address and the number of execution instructions at a plurality of time points, the number of execution instructions indicating number of instructions executed after precedent time point among the plurality of time points;
• calculate a first execution frequency of the instruction included in the block in each of the plurality of blocks based on the extracted execution address and the number of execution instructions;
• calculate a second execution frequency of the instruction belonging to the instruction type by multiplying the first execution frequency of the block by the percentage of the instruction in the block;
• calculate total number of second execution frequencies calculated for each of the plurality of blocks;
• and
• store the calculated total number of the second execution frequencies to the memory.

A non-transitory computer readable medium having stored therein a program that causes a computer to execute a process, the process comprising:

• calculating a percentage of an instruction belonging to a certain instruction type among instruction types included in a block, the block being one of a plurality of blocks partitioned from a program;
• extracting an execution address and a number of execution instructions from an arithmetic processing unit that executes the program and performs sampling of the execution address and the number of execution instructions at a plurality of time points, the number of execution instructions indicating number of instructions executed after precedent time point among the plurality of time points;
• calculating a first execution frequency of the instruction included in the block in each of the plurality of blocks based on the extracted execution address and the number of execution instructions;
• calculating a second execution frequency of the instruction belonging to the instruction type by multiplying the first execution frequency of the block by the percentage of the instruction in the block;
• calculating total number of second execution frequencies calculated for each of the plurality of blocks;
• and
• storing the calculated total number of the second execution frequencies to a memory.
