[petsc-users] Difference between opt and debug

[user_gong Kim]

Hello,


I have some issues about different mode and different command.

1. Exactly the same code, but no error occurs in debug mode, but an error
occurs in opt mode.
In this case, what should I be suspicious of?


2. When executed with ./application, no error occurs, but when executed
with mpiexec -n 1 ./app, an error may occur. What should be suspected in
this case?


Thanks,
Hyung Kim
