Running the Socket version

Since the socket implementation is experimental, there is currently no startup script provided. The executables have to be started on all hosts manually. Startup is defined by several environment variables. For all hosts set:

NETLIB_MASTER_PORT

Network port used by the coordinator

NETLIB_WORLD_SIZE

Total number of hosts, including coordinator

Only for slave hosts, you have to provide the hostname of the coordinator in NETLIB_MASTER_HOST.
