Procedure

1. Use PuTTY to log in to the server as the root user.
2. Run the following command to install the dependency:

   yum install blas lapack zlib boost -y

3. Run the following command to decompress the deal.II installation package:

   tar -xzvf dealii-9.1.1.tar.gz

4. Run the following command to switch to the directory generated after decompression:

   cd dealii-9.1.1

5. Run the following commands to create and access the directory for compiling deal.II:

   mkdir build
   cd build

6. Run the following commands to perform compilation and installation:

   CC=mpicc CXX=mpicxx FC=mpif90 cmake -DDEAL_II_WITH_THREADS=OFF -DDEAL_II_COMPONENT_DOCUMENTATION=ON -DDEAL_II_WITH_MPI=ON -DCMAKE_INSTALL_PREFIX=/path/to/DEALL.II ../

7. Run the following command to modify the build.make file:
   1. Open build.make.

      vi tests/quick_tests/CMakeFiles/mpi.debug.run.dir/build.make

   2. Press i to enter the insert mode and add the content in bold to line 52 in the build.make file.

      cd /storage/software/TaiShan/dealii/src/build/tests/quick_tests && /storage/software/TaiShan/openmpi/openmp    i-4.0.1-gcc9.1-hcoll/bin/mpiexec --allow-run-as-root -mca btl ^openib -np 2 ./mpi.debug > mpi.debug-OK 2>&1 || ( ec    ho mpi.debug:\ RUN\ failed.\ Output: && cat mpi.debug-OK && rm mpi.debug-OK && exit 1 )

   3. Press Esc, enter :wq!, and press Enter to save the file and exit.
