[petsc-users] VecScale failed because the local size mismatch

[Qiyue Lu]

Hello,
I have a vector (petsc_temp2) with size 1182 on my laptop without MPI.
However, when I tried to call
VecScale(petsc_temp2,  1.0/2.0);
It failed with
Cannot change/reset vector sizes to -1 local 1182 global after previously
setting them to 1182 local 1182 global

I wonder how this comes out and how the local size could be -1?

Thanks
Qiyue Lu
