Step 0: Hamachi
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install net-tools

https://www.vpn.net/linux
logmein-hamachi_2.1.0.203-1_amd64.deb
cd Descargas
sudo dpkg -i <archivo>.deb
sudo hamachi login
sudo hamachi attach <email@>
sudo hamachi do-join 461-293-533
sudo hamachi

cd ~
sudo nano /etc/hosts
agregar IPs
xxx.xxx.xxx.xxx     master
xxx.xxx.xxx.xxx     worker1
xxx.xxx.xxx.xxx     worker2
Ctrl+O ENTER Ctrl+X


Step 1: INSTALL SSH

sudo apt-get install openssh-server

mkdir ~/.ssh
chmod 700 ~/.ssh

ssh-keygen -t rsa
/home/mpiu/.ssh/id_rsa_<worker n>
enter enter enter

scp id_rsa_<worker n>.pub mpiu@master:~/.ssh
pones yes creo
y clave 654321

cat /home/mpiu/.ssh/id_rsa_master.pub >> /home/mpiu/.ssh/authorized_keys

cd ~
sudo nano /etc/ssh/sshd_config
PermitRootLogin yes
RSAAuthentication yes
PubkeyAuthentication yes
PasswordAuthentication yes
Ctrl+O ENTER Ctrl+X

sudo service ssh restart

ssh master

Step 2: INSTALL NFS
(master)
sudo apt-get install nfs-kernel-server
sudo mkdir -p /home/mpiu/share
sudo chown nobody:nogroup /home/mipu/share
sudo chmod 777 /home/mpiu/share
sudo nano /etc/exports

/home/mpiu/share worker1(rw,sync,no_subtree_check)
/home/mpiu/share worker2(rw,sync,no_subtree_check)
sudo exportfs -a
sudo systemctl restart nfs-kernel-server

sudo ufw status

(workers)
sudo apt-get install nfs-common
sudo mkdir ~/share
cd ~
#####sudo mount master:/home/mpiu/share /home/mpiu/share
sudo nano /etc/fstab
master:/home/mpiu/share home/mpiu/share nfs
Ctrl+O ENTER Ctrl+X

sudo mount -a
sudo ufw status

Step 3: INSTALL OPENMPI

sudo apt-get update
sudo apt-get install gcc openmpi-bin openmpi-common libopenmpi-dev libgtk2.0-dev

luego ir a https://www.open-mpi.org/software/ompi/v4.1/
descargar el openmpi-4.12.tar.gz y guardar en descargas

ir a carpeta descargas desde la consola y (descomprimir creo)
cd Descargas
tar -xvf openmpi-4.1.2.tar.gz

ir a la carpeta openmpi-blabla e instalar(esto es lo que demora)
cd openmpi-4.1.2/
./configure --prefix="/home/mpiu/.openmpi"
make
sudo make install

ahora exportar el PATH
export PATH="$PATH:/home/mpiu/.openmpi/bin"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/mpiu/.openmpi/lib"

verficar con
mpicc --version
mpiexec --version
mpirun --version

Step 4: RUN TESTS

mpirun -hosts manager,worker1,worker2 ./test
