Dear all,
What is the correct way to build PETSc with Scalapack/Blacs from MKL?
I tried:
—with-scalapack-lib=/path/to/mkl/lib/intel64/libmkl_scalapack_lp64.so
/path/to/mkl/lib/intel64/libmkl_blacs_openmpi_lp64.so
—with-scalapack-include=/path/to/mkl/include
but PETSc config fails to compile a test program and gives a lot of
“undefined reference to ‘ompi_mpi_real’, ‘MPI_Allgather’,
‘MPI_Cart_create’” etc from libmkl_blacs_openmpi_lp64.so.
Strangely enough I do see “-lmpi_f90 -lmpi_f77 -lmpi” in the compiler line, so
i don’t know why these symbols are missing.
Also MPI wrapper is used (/usr/bin/mpicc).
I already built MUMPS without a problem and even tests run ok, so I am quite
puzzled whether it’s something related to PETSc or MKL.
p.s. I use OpenMPI provided by Ubuntu.
Kind regards,
Denis
