Parallelizing Gstat for CS267 Final Project

1. Read in measurements (value and coordinates)
2. Determine all the pairs of points
3. For each pair of points
   • Calculate squared difference of values
   • Calculate distance from coordinates
   • Add the squared differnce to the appropriate distance bin
4. Divide the sum of squared differences by the number of pairs in bin
5. Print output

This software uses some small subset of recent features from C++14 which your compiler must support. In particular, it should work on gcc version >= 4.9.

From root directory:

module switch PrgEnv-pgi PrgEnv-gnu
cd implementations
make

The output executable will be placed in implementations/bin. For instance, you can run the mpi-naive implementation:

cd implementations/bin
aprun -n <numcores> ./mpi-naive <input-path>

The Makefile is set up to use 'CC' as a compiler. If you want to use a different compiler, you can override the MPICXX (defines the MPI C++ compiler to use) or CXX (defines the C++ compiler to use, for non-MPI modules) variables as arguments to make. For example, if you want to use the mpic++ compiler:

make MPICXX=mpic++
