=head2 DIFFERENCES BETWEEN map(soveran) AND GNU Parallel
|

|

B<map> does not run jobs in parallel by default. The README suggests using:
|
||||
|
||||
... | map t 'sleep $t && say done &'
|
||||
|
||||
But this fails if more jobs are run in parallel than the number of
|
||||
available processes. Since there is no support for parallelization in
|
||||
B<map> itself, the output also mixes:
|
||||
|
||||
seq 10 | map i 'echo start-$i && sleep 0.$i && echo end-$i &'
|
||||
|
||||
The major difference is that GNU B<parallel> is build for parallelization
|
||||
and map is not. So GNU B<parallel> has lots of ways of dealing with the
|
||||
issues that parallelization raises:
