[petsc-users] Question about time issues in parallel computing

[­권승리 / 학생 / 항공우주공학과]

Dear petsc developers.

Hello.
I am trying to solve the structural problem with FEM and test parallel
computing works well.

However, even if I change the number of cores, the total time is calculated
the same.

I have tested on a simple problem using a MUMPS solver using:
mpiexec -n 1
mpiexec -n 2
mpiexec -n 4
...

Could you give me some advice if you have experienced this problem?

Best regards
Seung Lee Kwon
