Let's say you divide the work among 10 machines. On the first one you'd 
say --node=1/10, on the second you'd say --node=2/10 instead, and so on.

Or you could divide it into work-pieces using the same option: Pick a 
huge node number such as 1000000, then have something keep track of 
which pieces are done and which are not. To attack piece number 42, the 
syntax is --node=42/1000000.

Having said that, your task is impossible: The keyspace for 48 unknown 
digits is 1.0E+48 (ten to the power of 48). If you split the job among 
all GPU's in the entire world, it will *still* take way way *way* longer 
to crack (given average luck) than the time since last Big Bang. Winning 
the EuroJackpot five consecutive times in a row would be more likely 
(literally, unless I miscalculated it). Or put another way: Not even the 
first piece from the second example above, --node=1/1000000, would 
"ever" complete.
