Pyrit in a lab

A student at the John von Neumann Faculty of Informatics / University of Óbuda turned a computer lab (with the blessing from his teacher) into a cluster of 19 Pyrit-running nodes. Using a GeForce GTX260 GPU on each node, he was able to achieve a performance of 126.000 Pairwise Master Keys per second.

While these GPUs are in no terms up to date, it is still an impressive example: 2.064.384.000 rounds of SHA1 or 123 gigabytes of data crunched every second in a network of 19 low-cost PCs.
