Abstract: A recording medium stores a program for causing a computer to execute processing including: causing a convolution layer to execute a convolution calculation of forward propagation on first data output from a layer closer to an input side than the convolution layer; generating, when a pooling layer is caused to execute a pooling calculation of forward propagation on output data, an index in which a position of a non-zero element is set for each element of the output data; and causing, when the convolution layer is caused to execute a convolution calculation of backward propagation of the first data and second data that is output from a layer closer to an output side than the pooling layer, the convolution layer to execute a convolution calculation of a non-zero element based on the index, the input data, and the second data, and to skip a convolution calculation of a zero element.

Abstract: The present disclosure relates to a non-transitory computer-readable recording medium storing an analysis program that causes a computer to execute a process. The process includes sampling an instruction address of one of instructions included in a program during execution of the program, identifying a first function that includes the sampled instruction address in an address range, rewriting mark information associated with the identified first function, identifying first information corresponding to the instruction address of the first function among a plurality of first information based on the rewritten mark information, identifying second information corresponding to the instruction address of the first function among a plurality of second information based on the rewritten mark information, storing the first information and the second information in a memory, and analyzing performance of the program based on the first information and the second information stored in the memory.
