EE451_Proj_Viterbi

Type make to compile files. Type "./main" to run the program.

The code is dedicated for USC HPC.

Before you run it, remember to set the paramemters in main.cpp or mpi.cpp or openmp_mpi.cpp and compile it!

LTDP with openMP

To compile : g++ -std=c++11 -O3 -c main.cpp viterbi.cpp parallel_viterbi.cpp util.cpp -fopenmp

TO link: g++ -std=c++11 -O3 -o main main.o viterbi.o parallel_viterbi.o util.o -fopenmp

TO run: srun -n1 -c2 ./main (c2 means 2 processors)

LTDP with MPI

First, setup MPI toolchain by typning ‘source /usr/usc/openmpi/default/setup.sh’

To compile: mpic++ -std=c++11 -O3 -c util.cpp mpi.cpp viterbi.cpp

To link: mpic++ -o mpi util.o mpi.o viterbi.o

TO run: srun -n4 ./mpi (-n4 means 4 nodes)

LTDP with both OpenMP and MPI

First, setup MPI toolchain by typning ‘source /usr/usc/openmpi/default/setup.sh’

To compile: mpic++ -std=c++11 -O3 -c util.cpp openmp_mpi.cpp viterbi.cpp -fopenmp

To link: mpic++ -o openmp_mpi util.o openmp_mpi.o viterbi.o -fopenmp

To run: srun -n2 -c2 ./openmp_mpi (this means 2 processors in 2 nodes = 4 processors in total)
