Thank you for your reply, Matt. I have checked the tutorials. They just use specified values and MatSetValues() to make a parallel matrix. Now, the matrix I use is in a single node of the cluster. I have 'M' nodes in this cluster. I need to copy the sequential matrix to other 'M-1' nodes and then use MatSetValues() or I just use MatSetvalues() in the node where the matrix is? The latter should work, right? thanks.
