| Abstract: | According to the common block-cyclic data distribution,this paper brings forward an improvement program of data reallocation phases,designs and carries out the improved data reallocation parallel algorithm on the basis of the two-phase I/O method.Experimental results show that in block-cyclic data distribution,compared with traditional data reallocation algorithm,the algorithm gains better parallel I/O performance. |
