Password distribute for parallel processing

[validator]

I want to develop custom password recovery so I want to learn How to distribute passwords between worker machines. We can use MPI or HADOOP technology to parallelize. If we create all passwords in master machine for 10 characters, it require more 80000 tera. If we create passwords in workers, I must develop smart distributing strategy. so Do you have any experiences about distributing passwords. In addition, which technolohy do you prefer MPI or HADOOP.
