WebApr 9, 2024 · 0. CUDA (as C and C++) uses Row-major order, so the code like. int loc_c = d * dimx * dimy + c * dimx + r; should be rewritten as. int loc_c = d * dimx * dimy + r * dimx + c; The same with the other "locs": loc_a and loc_b. Also: Make sure that the C array is zeroed, you never do this in code.
