Abstract—Through the research of the parallel computational model based on the principal and subordinate mode and the basic theory of Gmres Algorithm in Krylov subspace, this essay raises a improvement parallel Predict-Correct Gmres(m) algorithm which posses Predict-Correct pattern, and shows the computing examples for linear equations. After the comparison with the result from the new parallel Predict-Correct GMRES(m) algorithm, at last one application is given for thin plate structures, it shows that this designed parallel algorithm can reduce the iteration frequency, shorten the computing time and obtain
