I got the following error messages on each processor when use mpiio: [5]PETSC ERROR: DMDAArrayMPIIO() line 532 in MyLocal/petsc/petsc-3.4.3/src/dm/impls/da/gr2.c [5]PETSC ERROR: VecView_MPI_DA() line 605 in MyLocal/petsc/petsc-3.4.3/src/dm/impls/da/gr2.c [5]PETSC ERROR: VecView() line 717 in MyLocal/petsc/petsc-3.4.3/src/vec/vec/interface/vector.c
The program does not crash, but skip writing the binary output. Thank you.
