mpibzip2 - parallel bzip2 for cluster machines
Jeff Gilchrist has released mpibzip2, a parallel implementation of the popular bzip2 block-sorting file compressor that uses MPI and achieves significant speedup on cluster machines.
Similar to his pbzip2 multi-threaded bzip2, the output is fully compatible with bzip2. The results show a near linear speed-up for upto 30 nodes.
