weather-buoys

Processing weather buoy data in parallel.

Getting started

Dependencies

This repo assumes you are working with GNU Fortran compiler and an OpenCoarrays wrappers caf and cafrun. If you are working with other coarray-enabled compiler such as Intel or Cray compilers, edit the FC variable in the Makefile.

Getting the code

git clone https://github.com/modern-fortran/weather-buoys

Compiling the programs

cd weather-buoys
make

Running the serial program

./weather_stats

If you run the program with the dataset included in this repo, you will get the output similar to this:

 Maximum wind speed measured is    40.9000015     at station 42001
 Highest mean wind speed is    6.47883749     at station 42020
 Lowest mean wind speed is    5.43456125     at station 42036

Running the parallel program

Run the program on 2 parallel images:

cafrun -n 2 ./weather_stats_parallel

The result should be the same as in the serial program, but will complete somewhat faster, depending on the number of cores available and number of images you invoke. You can run the program on any number of images, but no more than the number of files in dataset (9).
