Hi, I tried running ex19.c and I get the following error (I added a small snippet to print the local size on rank0 as well) :
[sajid@xrm temp]$ mpirun -np 2 ./ex19 local_sizes : 3 4 [1]PETSC ERROR: --------------------- Error Message -------------------------------------------------------------- [1]PETSC ERROR: Arguments are incompatible [1]PETSC ERROR: Incompatible vector local lengths parameter # 1 local size 3 != parameter # 2 local size 2 [1]PETSC ERROR: See http://www.mcs.anl.gov/petsc/documentation/faq.html for trouble shooting.
