it's a bit more fun (though harder to sort the output) if you do

for a in $(seq 1 100); do rsh -n note-$a w & ; done

and the obvious refinement is to prefix each line with the node name,
then use sort with whatever parameters make it sort on the first
column with no regard for other columns.  

it's those "whatever parameters" that keep me from backgrounding N rsh
jobs on a regular basis.  but for lots of tasks i can get away with it
( for example, the emulex fiber channel driver takes 10 seconds to
load.  on a 33 node cluster, that adds up fast )
