[Running EPSILON cluster]
1. Build EPSILON with cluster support (see INSTALL for details)
2. Run `epsilon --start-node' on each SLAVE node. Default port 2718
can be changed using `--port' option. EPSILON node daemon logs
messages to syslog using `daemon' facility.
3. Create file with list of cluster nodes on MASTER server.
File format: user@host:port^number_of_CPUs
host - EPSILON node's hostname or IP
port - EPSILON node's port
number_of_CPUs - number of simultaneous connections to that SLAVE node
user - SSH login (used by start_epsilon_nodes.pl and stop_epsilon_nodes.pl)
4. Run epsilon from MASTER server as usual but pass `--node-list' option.
Check logs on SLAVE nodes.
5. There are several default places for epsilon.nodes file.
Please consult manual on this matter
6. There are two helper script start_epsilon_nodes.pl and stop_epsilon_nodes.pl
that can be used to simplify starting/stopping EPSILON nodes.
These script run `epsilon --start-node' on hosts, listed in
epsilon.nodes file using DSH - Distributed SHell.
