摘　　要：This paper presents the Cp, criterion and a parallel algorithm with regard to the large-scale linear regression model. The scalability for the algorithm is analyzed. And the results for the algorithm on a group of computers are given. The quite good speed-up ratio is obtained.This paper presents the Cp, criterion and a parallel algorithm with regard to the large-scale linear regression model.
