There is an example in cryptsetup source which tries passphrases from file and also supports parallel search on multi core CPUs. You can also split generated file and start part of search on another machine (you need to copy LUKS header - first 4MB of the disk shoud be enough or better you can use luksBackup). Download source or see http://code.google.com/p/cryptsetup/source/browse/#git%2Fmisc%2Fdict_search (try it on some example first if it works for you, it was just quick example, of libcryptsetup use and not much tested ... and read README) Milan
