Research on max ordinal in universal combinatorics coding based on GPU parallel computing

The parallel computing method of max ordinal number in universal combinatorics coding based on GPU is advanced in this paper. The core of universal combinatorics coding computing is ordinal number computing while the calculation of ordinal number depends on the value of max ordinal number. The calculation of max ordinal number is divided into two parts, multiplication and division of large numbers. This paper focus on the GPU parallel computing of the multiplication in max ordinal number calculation, the calculation speed of the multiplication part is increased substantially, and thus improves the efficiency of max ordinal number calculation.
