a parallel algorithm for finding Closest pair in 2-D space

You should have OPEN-MPI standard installed on your system. version 1.8.1 or later. you shall compile it like: mpicc parallel-Closest-Pair.c -lm -o parallel-Closest-Pair.o then run it with: mpirun -n [num 0f processes] parallel-Closest-Pair.o [input, sth dividable by num of processes]
