Repository of codes for labs:

1. Data Mining Laboratory
2. Distributed Computing Laboratory

Commands to execute OpenMP programs:

Get necessary packages (one time step):

sudo apt-get update
audo apt-get upgrade
sudo apt-get install libopenmpi-dev libgd-dev

To compile and run codes:

gcc <filename>.c -fopenmp -lgd -lm
./a.out

Commands to execute MPI programs:

Get necessary packages and setup (one time step):

sudo apt-get install mpich mpich-doc
sudo update-alternatives --config mpi #you may need to select a certain MPI installation

To compile and run codes:

mpicc <filename>.c
mpirun -np 4 ./a.out 
#try mpiexec if mpirun does not work
#try with -np 2 if 4 does not work 

Commands to execute R codes:

Get necessary packages and setup (one time step):

$ install.packages("<package-name>") #you may need to run this using root access in the R prompt, as the installation usually requires a file write

To compile and run codes:

$ R -f <file>.R

Alternatively, you may choose to run the R codes in R Studio.
