Sean O'Rourke's code for the Wide Finder benchmark does something very similar, you might need to change only a few lines. The idea is to partition the input file into n partitions for n processes, forked via a pipe open. Each one works independently on its part of the file, storing its result into a hash, then passing the hash back to the parent on STDIN using Storable. Then you just need to merge the hashes into one.
