[petsc-users] Argument out of range error in MatPermute

Thank you for your answers. I figured out that for a matrix of size
4253*4253, local size of Mat is 2127 and 2127 for 2 processors. However, I
wrote the program such that the local sizes of IS 2127 and 2126.

Is local size of Mat being 2127 on both processors correct? If it is, then
I will change the local size of IS but then it will exceed the global size
of Mat. Isn't this also a problem?

Thanks a lot,

Eda
