Installing PETSc

Procedure

1. Use PuTTY to log in to the server as the root user.
2. Upload the METIS, ParMETIS, f2cblaslapack, and SUNDIALS installation packages to the /path/to/PETSC directory.
3. Decompress the PETSc installation package.

   cd /path/to/PETSC
   tar -xvf petsc-lite-3.6.2.tar.gz

4. Go to the directory generated after the decompression.

   cd petsc-3.6.2

5. Load environment variables.

   export CC=`which gcc`
   export CXX=`which g++`
   export FC=`which gfortran`

6. Perform the configuration.

   ./configure --with-make-np=4 --with-fc=0 --with-x=false --with-ssl=false --download-f2cblaslapack=/path/to/PETSC/f2cblaslapack-3.4.2.q1.tar.gz --download-parmetis=/path/to/PETSC/parmetis-4.0.3-p2.tar.gz --download-sundials=/path/to/PETSC/sundials-2.5.0p1.tar.gz --with-shared-libraries --with-mpi-dir=$MPI_DIR --download-metis=/path/to/PETSC/metis-5.1.0-p1.tar.gz --download-hdf5=/path/to/PETSC/hdf5-1.8.16.tar.bz2

   

   • In the previous command, the --download parameter indicates that all the other software will be also installed.
   • The --download parameter can be in a format similar to --download-hdf5=1 or a format with a specified path. In the former format, the software will be downloaded and installed from the Internet; in the latter format, the software will be installed from the specified path.
   • If the problem described in Troubleshooting is reported when you perform step 6, refer to the solution described in Problem 1: An Error Is Reported During PETSc Configuration. After the fault is rectified, perform step 6 again.
7. Perform the installation.

   make

8. Set the environment variables.

   export PETSC_DIR=/path/to/PETSC/petsc-3.6.2
   export PETSC_ARCH=linux-gnu
   export SUNDIALS_ROOT=$PETSC_DIR/$PETSC_ARCH
   export HDF5_ROOT=$PETSC_DIR/$PETSC_ARCH
