[petsc-users] Expecting Explanation

[Fazlul Huq]

Hello PETSc developers,

In example 6 or vec section I don't understand this line:
if (size != 1) SETERRQ(PETSC_COMM_SELF,1,"This is a uniprocessor example
only!");

I tried to run the code with "mpiexec -n 2 ./ex6" or "mpiexec -n 4 ./ex6"
or even "mpiexec -n 1 ./ex6" it the code runs properly.

Thanks.

Sincerely,
Huq
