Abstract:

Aiming at the data distribution problems on distributed memory multiprocessors, we propose an effective data distribution approach based on data trans  formation techniques in this paper under the condition that the program has been parallelized. This approach can effectively distribute multidimensional
  arrays with general affine array subscripts in multiple loop nests, We also consider the offset constant alignment problems in the approach and thus da ta communication overheads can be reduced as much as possible. The experimental results show the approach presented in this paper is effective.

Key words: （distributed memory multiprocessors;data transformations, data distribution）
