Embodiment 1
[0074] A performance evaluation method for many-core applications based on domestic supercomputing micro-architecture, the specific method is as follows:
[0075] 1) Model input includes Lat_SPM, n_v, n_scalar_i, n_scalar, n_arr_i_get, n_arr_ge, n_arr_i_put, n_arr_put, d_size, n_iasm, n_iasmi, n_dasm, n_ddiv, n_cmp, n_1d, n_2d, n_3d, n_i_siz, n_size, n_cpe_m, n_com, , T_cpe, n_cmp, n_gsize, n_psize, T_g1, T_p1, n_core;
[0076] Among them, Lat_SPM is the delay of accessing from the core office memory, and the unit is cycles; n_v is the number of array variables; n_scalar_i is the number of integer scalars; n_scalar is the number of floating-point scalars; n_arr_i_get is the read-in integer array n_arr_get is the number of floating-point arrays read in; n_arr_i_put is the number of output integer arrays; n_arr_put is the number of output floating-point arrays; d_size is the size of a single array; n_iasm is the loop Outside, the number of integer addition, subtraction, and mul...
