Parallel programming: Solving PDE

Solve Poisson equation by hybrid programming with OpenMP and MPI.

Compile

Replace the compiler path with yours and then execute the following commands.

$ cmake -DCMAKE_DEBUG_TYPE=Release

$ make

Usage

• -np: number of processors
• —grids: size of grids
• —threads: number of threads
• —method: 0 for hybrid OpenMP-MPI, 1 for OpenMP only, default for Sequential method
• —output: output path

$ mpirun -np 6 ./pde --grids 100 --threads 3 --method 0 --output u.data

$ ./pde --threads 3 --method 1

$ ./pde --method 2
