Likely this build is with gnu compilers.

The above suggests - the following might work:
'--with-blaslapack-lib=-L/opt/intel/mkl/lib/intel64 -lmkl_intel_lp64
-lmkl_gnu_thread -lmkl_core -lgomp -lpthread -lm -ldl'

Yes PETSc prefers sequential MKL - as MPI handles parallelism.
One way to trick petsc configure to use threaded MKL is to enable pardiso. i.e:
--with-blaslapack-dir=/opt/intel/mkl --with-mkl_pardiso-dir=/opt/intel/mkl

Could you precise what is PMI? and how can we directly use it? It might
be a key to this mystery!

Hi Matthew,
Does it mean that by using just command python3 simple_code.py (without
mpiexec) you *cannot* obtain a parallel execution?
It s been 5 days we are trying to understand with my colleague how he
managed to do so.
It means that by using simply python3 simple_code.py he gets 8 processors

Dear PETSC community,
I have a question regarding the parallel execution of petsc4py.
I have a simple code (here attached simple_code.py) which solves a system
of linear equations Ax=b using petsc4py. To execute it, I use the command
python3 simple_code.py which yields a sequential performance. W
