            <br>
            I compiled PETSc with Intel MPI (MPICH) and GCC as compiler
            (i.e. using<br>
            Intel OneAPI together with the supplied mpicxx-compiler).
            Compilation<br>
            and installation worked fine, but running the tests resulted
            in the<br>
            error "Attempting to use an MPI routine before initializing
            MPICH". A<br>
            simple test program (attached) worked fine with the same
            combination.<br>
            <br>
            What could be the reason for that?<br>
