我有以下程式碼：
Concretely, the algorithm works as follows: Given an n x m grid with 'k' processes, we split up the grid horizontally into 'k' chunks, where each process is responsible for its own chunk. Each chunk is padded with extra halo regions at the top and bottom (with the exception of the topmost and bottom-most chunks -- these will have exactly one extra halo region). We then use MPI interface to allow processes to exchange halo regions with each other and compute the stencil algorithm on their respective chunks.

我想將圖像拉到第 1 頁的底部。
