How to install or setup PETSc

Environment: mpich-1.2.7p1 (/usr/opt/mpich)
Intel MKL on Windows or Linux (/usr/opt/int/mkl)
Assume I had install MPICH and BLAS & LAPACK.
Therefore, if you want to install single computer PETSc without MPICH

1. PETSC_DIR=$PWD; export PETSC_DIR
2. ./config/configure.py --with-cc=/opt/intel/cc/10.0.14/bin/icc --with-cxx=/opt/intel/cc/10.0.14/bin/icpc --with-fc=/opt/intel/fc/10.0.14/bin/ifort --with-blas-lapack-dir=/usr/opt/intel/mkl/10.0.1.014 --with-mpi=0
3. make all
4. make test
   

• Install PETSc with MPICH

1. PETSC_DIR=$PWD; export PETSC_DIR
2. ./config/configure.py --with-blas-lapack-dir=/usr/opt/intel/mkl/10.0.1.014 --with-mpi-dir=/usr/opt/mpich --with-clanguage=cxx --with-cxx=/usr/opt/mpich/bin/mpicxx
3. make
   
4. make test

BLAS/LAPACK: these packages provide some basic numeric kernels used by PETSc.

• /usr/lib/libblas.a,liblapack.a
• Intel MKL on Windows or Linux
• sunperf on solaris
• VecLib on Macs
• IBM ESSL

Alternatively one can use other externalpackages installation options like the following.

• --with-blas-lapack-lib=libsunperf.a
  

• --with-blas-lib=libblas.a --with-lapack-lib=liblapack.a
• --with-blas-lapack-dir=opt/intel/mkl72

If using MPICH which is already installed [perhaps using myrinet/gm] then use:
. /config/configure.py --with-mpi-dir=/path-to-mpich-install
