-snes_type test

[(Rebecca) Xuefei YUAN]

Hi,

I am testing my hand coded jacobian matrix in multi processors with  
the option "-snes_type test -snes_test_display", and I find that
1) my hand coded jacobian is different from the finite difference  
jacobian running with 2 processors.
But
2) my jacobian is the same as the finite difference jacobian matrix  
running with 1 single processor.
Also
3) my hand coded jacobian with 1 processor is the same as my hand  
coded jacobian with 2 processors.

Where could be wrong about multiprocessors' jacobian matrix?

Thanks very much!
