Hello
I am a beginner of PETSc.I find the petsc-users lists is very useful,
however I do not know how to ask a question in it. So can you tell me? And
below is what I want to ask.
I am solving Ax=b with PETSc. And I only use it in a fortran subroutine to
get x ,then the main function of my program use x to do other things. The
question is that: when the process is 1(mpiexec -n 1),the result of my program
is ok, but when the process is more than 1 the result is wrong.
So where could be wrong? Can you give me some hints on how I can debug?
Thanks.
Jim
