Parallel Computing

Procedure

1. Use PuTTY to log in to the server as the root user.
2. Go to the directory where the test case is stored.

   cd examples/laminar/cylinder2d

3. Compile the test case.

   make

4. Run the program to perform the computing. The following uses -np=64 and OMP_NUM_THREADS=1 as an example.

   mpirun –allow-run-as-root –np 64 –x OMP_NUM_THREADS=1 ./cylinder2d

   The generated VTK and gnuplot results are stored in the /tmp directory.
