[AUR] pbzip2 - Parallel BZIP2 - Data Compression Software

judfilm · 2007-06-04 04:42:01

PBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 v1.0.2 or newer (ie: anything compressed with pbzip2 can be decompressed with bzip2).

Just finished the initial release of the PKGBUILD, grab it here.

Please let me know of any problems or further requests.

PS: Get me some single core packages to build too, I still didn't get a multi core machine.

Hi Anakin,

Thank you for your great work on the PKGBUILD! PBZIP2 works great - nice speed up.

You're welcome.

Are you running x86_64? If so, did it build flawlessly?

i had played in the past with it coming to this one replacing the bzip2 bins:

}

as it won't work in pipes it's quiet useless as no tar.bz2 are allowed. that's why i had stopped working on it.

Didn't know that, it's certainly a must. Guess I'll mail that as a feature request to the developer.

Input from stdin and pipes are already on the TODO list according to pbzip2's website.
