At first, make sure you use linux operating system. Code is test on ubuntu 16.04. Make sure openmpi is installed on your system.
Run following command: cmake . && make and you can get the executable program.
Currentely, we can run it on single machine by mpiexec -n 3 ./dis_ffm, which you will use one process as a server and the other two processes are used for training.
Of course, you can run the program on multiple machines.
