[petsc-users] Tutorials test case cannot run in parallel

[袁煕]

Hi,

I have tried the test case ex3f90 in the folder
\src\dm\impls\plex\tutorials to run in parallel but found it fails. When I
run it in 1 CPU by

-  mpirun -np 1 ./ex3f90

Everything seems OK. But when run it in 2 CPU by

-  mpirun -np 2 ./ex3f90

I got the following error message

[0]PETSC ERROR: --------------------- Error Message

It fails in calling DMPlexInterpolate. Maybe this program is not considered
to be run in parallel. But if I wish to do so, how should I modify it to
let it run on multiple CPUs?

Much thanks for your help
