Re: [petsc-users] error: Petsc has generated inconsistent data, MPI_Allreduce() called in different locations (code lines) on different processors
You have MatSetOption inside of a loop for the number of rows. This is apparently a collective operation. Move it to line 156.

Re: [petsc-users] error: Petsc has generated inconsistent data, MPI_Allreduce() called in different locations (code lines) on different processors
Dear Barry, Thank you for answering. I am sending my code, makefile and 2 PETSc Binary File where airfoil1_binary has odd numbered size (the one I got error) and gr_30_30_binary has even numbered size (I got correct result). I got the error for lines 164 and 169. By the way, I think I have done something wrong at line 320 (I tried to allocate an array twice) but I just need to reduce the error in 164 and 169 then I will get to reduce the error in line 320.
