Hybrid Beowulf Computer cluster !

A Beowulf cluster consists normally of identical computers joined into a LAN using a network switch. My improvised cluster includes a Lenovo S10 notebook running Archlinux, a Raspberry Pi and an Orange Pi and they are linked using an old D-Link router i had laying around.
At a later point i removed the Orange Pi from the cluster to use in another project. So it can work with 2 computers/NODES.

To build such a cluster at least two computers/Raspberry's/etc with some Linux distribution installed are needed.The computers should be networked with IPs assigned (preferably static IPs). We call each computer a NODE and we create identical usernames (ex: bigboss) on all nodes with sudo access.

For a complete tutorial on building a cluster supercomputer CLICK HERE . The instructions are for building a Raspberry Pi cluster but they can be modified to build a hybrid cluster like the one i did.

Running a C program (example) that calculates PI on 2 nodes.
