Bwtzip OpenMP

A parallel version of the bwtzip project implemented by means of the OpenMP APIs

In this project, the bwtzip lossless data compression library from Stephan T. Lavavej was extended by means of OpenMP APIs in order to build a faster parallel version of the library. Moreover, a performances analysis was conducted to show to obtained speedup.

NOTE: This is neither an official version of the bwtzip project, nor an implementation intended to be distributed.
