COPACOBANA, the Cost-Optimized Parallel COde Breaker, is an FPGA-based machine which is optimized for running cryptanalytical algorithms. COPACOBANA is suitable for parallel computation problems which have low communication requirements. DES cracking is such a parallelizable problem: an exhaustive key search of the Data Encryption Standard (DES) takes no longer than a week on average with COPACOBANA. Other ciphers can be attacked too, and COPACOBANA can also be used for parallel computing problem outside cryptography.
You'll find much more information about COPACOBANA on the faq page of this site.
