Restructure your data so you have:
%device_info = (
device1 => { version => '1.4', module => [1, 2, 3], memory => '18k'
+},
device2 => { version => '1.4', module => [4,5,6], memory => '25k' },
device3 => { version => '1.2', module => [7,8,9], memory => '18k' },
);
Then it's easy to do operations in parallel. Having upside-down data structures
is nasty.
