### 3.7 Set network properties

Loadable Function: network_set (connections, key, val) ¶

  Set the property named by key to the value val for each machine specified by connections.

  This function can only be successfully called at the client machine. See `pconnect` for a description of the connections variable. connections can contain all connections of the network, a subset of them, or a single connection.

  Possible values of key: `'nlocaljobs'`: configured number of local processes on the machine (usable by functions for parallel execution); needs a non-negative integer in val, `0` means not specified.
