• $ means shell prompt

1. Install gcc

   1. go to ~/src

   $ cd ~/src
   

   2. install gcc (for cmake, takes few HOURS)

   $ mkdir gcc_src
   $ cd gcc_src
   $ curl -L -O http://ftp.tsukuba.wide.ad.jp/software/gcc/releases/gcc-7.3.0/gcc-7.3.0.tar.gz
   $ tar zxvf gcc-7.3.0
   $ mkdir objdir 
   $ cd gcc-7.3.0
   $ contrib/download_prerequisites
   $ cd ../objdir
   $ ../gcc-7.3.0/configure --prefix=$HOME/usr/local/gcc --disable-multilib
   $ make && make install
   

   update PATH and LD_LIBRARY_PATH to ~/.bashrc, but don't modify original export just append additional paths

   export LD_LIBRARY_PATH=$HOME/usr/lib:$HOME/usr/local/gcc/lib64:$HOME/usr/local/gcc/lib:$LD_LIBRARY_PATH
   export PATH=$HOME/usr/bin:$HOME/usr/local/gcc/bin:$PATH
   

   then restart remote shell or use source command

   source ~/.bashrc
   

   Check gcc is properly installed

   gcc --version
   

2. Install cURL

   $ cd ~/src
   $ curl -L -O https://curl.haxx.se/download/curl-7.60.0.tar.gz
   $ tar zxvf curl-7.60.0.tar.gz
   $ cd curl-7.60.0
   $ ./configure --prefix=$HOME/usr 
   $ make && make install
   

   update PATH and LD_LIBRARY_PATH to ~/.bashrc, but don't modify original export just append additional paths

   export LD_LIBRARY_PATH=$HOME/usr/lib:$HOME/usr/local/gcc/lib64:$HOME/usr/local/gcc/lib:$LD_LIBRARY_PATH
   export PATH=$HOME/usr/bin:$HOME/usr/local/gcc/bin:$PATH
   

   then restart remote shell or use source command

   source ~/.bashrc
   

3. Install CMAKE

   $ curl -L -O https://cmake.org/files/v3.10/cmake-3.10.3.tar.gz
   $ tar zxvf cmake-3.10.3.tar.gz
   $ cd cmake-3.10.3
   $ ./bootstrap --prefix=$HOME/usr/local/cmake
   $ make && make install
   

   update PATH and LD_LIBRARY_PATH to ~/.bashrc, but don't modify original export just append additional paths

   export LD_LIBRARY_PATH=$HOME/usr/local/cmake/lib:$LD_LIBRARY_PATH
   export PATH=$HOME/usr/local/cmake/bin:$PATH
   

   then restart remote shell or use source command

   source ~/.bashrc
   

4. Install PETSc (펫씨)

   1. Download PETSc (펫씨)

   cd ~/src
   curl -L -O http://ftp.mcs.anl.gov/pub/petsc/release-snapshots/petsc-3.9.0.tar.gz
   

   2. unzip

   tar zxvf petsc-3.9.0.tar.gz
   

   3. configure

   cd petsc-3.9.0
   ./configure --prefix=$HOME/usr/local/PETSc --download-fblaslapack --with-mpi-dir=/engrid/enhpc/mpich-3.2.1 --download-mumps --download-scalapack --download-parmetis --download-metis --download-ptscotch --download-trilinos, --download-hypre --download-superlu_dist
   

    1. If you want to install with GPU Support (CUDA)
    ```
    ./configure --prefix=/opt/PETSc --download-fblaslapack --download-mumps --download-scalapack --download-parmetis --download-metis --download-ptscotch --download-trilinos, --download-hypre --download-superlu_dist --with-cuda=1 --with-cusp=1 --with-cusp-dir=/opt/cusp
    ```
   

   4. make

   make all test
   

   5. install

   make install
   

   6. update Makefile using installed path

   $HOME/usr/local/PETSc
