heiko is a lightweight load balancer that uses SSH to manage servers running on
low-end hardware such as Raspberry Pis or even mobile phones.
The name heiko is derived from the Japanese term for equilibrium.
heiko uses a smart scheduler to run a program on one node from a set of nodes. It is very robust to node failures and switches to a different node as soon as the current node fails. The node to run is intelligently selected based on multiple factors such as CPU power, memory capacity, free memory, current CPU load, past failures and others.

- Configuring nodes using YAML.
- Nodes require only ssh to work.
- Scheduler ranks nodes based on node specifications, also uses load and free memory to decide which node to use.
- Run multiple jobs across nodes.
- Test heiko on a single machine.
- Sync files from master to nodes (requires rsync installed on both master and nodes). Ignore files to be synced with rsync-ignore
