如何强制将图像从下一页拉到当前页的底部？

Question

我有以下代码：

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. 


\begin{figure}[H]
    \centering
    \includegraphics[trim={0 0 0cm 0},clip,scale=0.4]{halo}
    \caption{Halo exchange between 3 processes using Row Decomposition}
    \label{fig:9-stars stencil}
\end{figure}
