+title: Installing PETSc and DAMASK on the CSF3

+
+This page aims to detail how to install PETSc (https://petsc.org/release/) and DAMASK (https://damask-multiphysics.org/) for simulating crystal plasticity.
+
+
+## Edit Bash Profile
+Before we begin, it is important to define some enviroment variables, these should be added to your `.bash_profile`, which can be accessed using the following commands.
+
+```
+cd
+
+vim .bash_profile
+```
+With the editor open, add the following lines of code to the bottom
+
+```
+export HDF5_USE_FILE_LOCKING=FALSE
+
+export PETSC_DIR=$HOME/software/petsc
+export PETSC_ARCH=mkl-opt
+
+export PATH=$PETSC_DIR/$PETSC_ARCH/bin:$PATH
+```
+
+Make sure to save and exit, you will need to logout and log back in for the changes to take effect. 
+
+## Install PETSc
+
+Now, we need to download and install PETSc, if you don't already have a software folder on the CSF3, then ensure you make on in your home directory. Once downloaded, it's important to make sure you are on the correct branch.
+
+```
+cd
+
+mkdir software
+
+cd software
+
+git clone https://github.com/petsc/petsc.git
+
+cd petsc
+
+git checkout release-3.19
+```
+
+Now that we have PETSc downloaded we need to configure it for use with DAMASK. We need to create a folder within PETSc to hold extra packaged required by DAMASK. This should be within the PETSc directory `software/petsc/mkl-opt`.
+
+```
+cd $PETSC_DIR
+
+mkdir mkl-opt
+```
+
+When configuring PETSc, it's best to either do so interactively or using a submission script. Here, we use a submission script that we can call `configure_petsc.sh`.
+
+```
+#!/bin/bash --login
+
+#$ -cwd
+#$ -N configure_petsc
+
+# Exports
+export HDF5_USE_FILE_LOCKING=FALSE
+
+# contains:
+module purge
+
+module load mpi/intel-19.1/openmpi/4.1.1
+module load tools/gcc/cmake/3.13.2
+
+cd $PETSC_DIR
+
+## For CSF3
+./configure \
+--with-cc=mpicc \
+--with-cxx=mpicxx \
+--with-fc=mpif90 \
+--download-fftw \
+--download-hdf5 \
+--download-hdf5-fortran-bindings=1 \
+--download-metis \
+--download-parmetis \
+--download-yaml \
+--download-zlib \
+--download-fblaslapack \
+--with-mkl_pardiso-dir=$MKLROOT \
+--with-mkl_sparse-dir=$MKLROOT \
+--with-mkl_sparse_optimize-dir=$MKLROOT \
+--with-blaslapack-dir=$MKLROOT \
+--with-debugging=0 \
+COPTFLAGS="-O2 -mavx2 -axCORE-AVX512,CORE-AVX2,AVX" \
+CXXOPTFLAGS="-O2 -mavx2 -axCORE-AVX512,CORE-AVX2,AVX" \
+FOPTFLAGS="-O2 -mavx2 -axCORE-AVX512,CORE-AVX2,AVX" \
+PETSC_ARCH=mkl-opt \
+PETSC_DIR=$(pwd)
+
+make PETSC_DIR=$(pwd) PETSC_ARCH=mkl-opt all
+make PETSC_DIR=$(pwd) PETSC_ARCH=mkl-opt check
+```
+This should run successfully and install PETSc. 
+
+## Install DAMASK
+
+Again, we can use git to download DAMASK. Here, we install the `release` branch, but you can use any branch or tag that you prefer.
+```
+git clone https://github.com/damask-multiphysics/DAMASK.git
+
+git checkout release
+```
+We will also use a submission script to make and install DAMASK, which we can call something like `install_damask.sh`.
+
+```
+#!/bin/bash --login
+
+#$ -cwd
+#$ -N install_damask
+
+# Exports
+export HDF5_USE_FILE_LOCKING=FALSE
+export OMP_NUM_THREADS=1
+export DAMASK_ROOT=$HOME/software/DAMASK
+
+source $DAMASK_ROOT/env/DAMASK.sh
+PATH=$PETSC_DIR/$PETSC_ARCH/bin:$PATH
+LD_LIBRARY_PATH=$PETSC_DIR/$PETSC_ARCH/lib:$LD_LIBRARY_PATH
+
+# contains:
+module purge
+
+module load mpi/intel-19.1/openmpi/4.1.1
+module load tools/gcc/cmake/3.13.2
+
+PETSC_DIR=$HOME/software/petsc
+PETSC_ARCH=damask
+
+cd $DAMASK_ROOT
+
+mkdir build
+cd build
+
+cmake -DCMAKE_INSTALL_PREFIX=../ -DDAMASK_SOLVER=GRID ../
+make all install
+
+```
+
+This should make and install DAMASK fairly quickly. Now we can define another enviroment variable (add this to your bash profile as well). 
+
+```
+export DAMASK_grid=$HOME/software/DAMASK/bin/DAMASK_grid
+```
+
+DAMASK can now be run on the command line by simply executing `$DAMASK_grid`. You will also need to specifiy the various input files, however information about this can be found on the DAMASK website (https://damask-multiphysics.org/).
