Parallel Programming

Use of MPI and OpenMP for some mathematical problems

COMMANDS
	ex: PRECISION			= 0.000001
	ex: NB_PROCESSUS / NB_THREADS	= 4

PI Calculation

arctan_1:
	COMPIL	=>	gcc -o arctan_1 arctan_1.c
	RUN	=>	./arctan_1 PRECISION

OpenMP:
	COMPIL	=>	gcc -o omp_arctan_1 arctan_1_omp.c
	RUN	=>	./omp_arctan_1 PRECISION

MPI (need mpich package installed):
	COMPIL	=>	mpicc -o mpi_arctan_1 arctan_1_mpi.c
	RUN	=>	mpirun -n NB_PROCESSUS ./mpi_arctan_1 PRECISION

pthread:
	COMPIL	=>	gcc -o pthread_arctan_1 arctan_1_pthread.c -pthread
	RUN	=>	./pthread_arctan_1 PRECISION NB_THREADS

MATRIX Product

product & openmp:
	COMPIL	=>	gcc -o [omp_]product [omp_]product.c
	RUN	=>	./[omp_]product

MPI (need mpich package installed):
	COMPIL	=> mpicc -o mpi_product mpi_product.c
	RUN	=> mpirun -n NB_PROCESSUS ./mpi_processus
