Thanks Matthew, i have made some progress but i am still unsure on how to
proceed to make the DMDAs work as intended, i will try to lay out what i am
trying now:
I was able to port the interpolation into the DMDA model but it works only
in serial runs, and it becomes unstable for more than one pro

Thanks,Matt
I'm sorry I didn't describe the problem clearly.
I'm still wondering how, although VecLoad supports parallel vector reading,
how can I guarantee that the local vector on the processor corresponds to
the DM's IS?
For example, when in FormInitialGuess, I want to make sure that the array

Thank you very much, Matt.
My problem is actually a two-dimensional problem, and the matrix in my
binary file is actually a two-dimensional array, each point corresponding
to a value on the two-dimensional grid.
Your suggestion is very useful to me. I can try to convert the matrix
binary file into

Dear Petsc developer:
Hi,
Thank you very much for your previous reply.
I recently wanted to modify my program to parallel version, and encountered
some problems in modifying it.
1. There are functions (read matrix) in the program that reads files,will
they affect my parallelism? The codes are as f
