How should he configure to this? remove "--download-fblaslapack=1" and add ....

1. If using gcc

module load mkl

with either compiler:

export BLAS_LAPACK_LOAD=--with-blas-lapack-dir=${MKLROOT}

2.  We define MPICH_HOME for you.

With Intel MPI:

  export PETSC_MPICH_HOME="${MPICH_HOME}/intel64"
  export mpi="--with-mpi-compilers=1 --with-mpi-include=${TACC_IMPI_INC} --with-mpi-lib=${TACC_IMPI_LIB}/release_mt/libmpi.so”

with mvapich:

  export mpi="--with-mpi-compilers=1 --with-mpi-dir=${PETSC_MPICH_HOME}”

(looks like a little redundancy in my script)
