[petsc-users] Runtime error

[Jorti, Zakariae]

Hi,


I have a PETSc code which works in some cases circumstances whereas in others it gives me the error message below.

The code works on my machine when I compile PETSc with debug flag on:

./configure PETSC_DIR=/Users/zjorti/software/petsc-3.14.5 PETSC_ARCH=macx --with-fc=0 --with-mpi-dir=$HOME/.brew --download-hypre  --with-debugging=1 --with-cxx-dialect=C++11



It does not work however when I compile Petsc with debug flag off:

./configure PETSC_DIR=/Users/zjorti/software/petsc-3.14.5 PETSC_ARCH=macx --with-fc=0 --with-mpi-dir=$HOME/.brew --download-hypre  --with-debugging=0 --with-cxx-dialect=C++11



I asked a colleague to test this same code.

He compiles PETSc with debug flag off, runs the code and it works for him. He has an older machine but we both use the same version PETSc version which is 3.14.5.


As I do not have any debugger I could not identify the cause of this runtime error.

One more thing: We did not run the code in parallel.

Is this a hardware related issue or is it something else?

Thanks,


Zakariae
