fgbzip2 sample

fgbzip2 is a parallel implementation of bzip2 block-sorting file compressor that uses oneapi::tbb::flow. The output of this application is fully compatible with bzip2 v1.0.6 or newer.

This example includes software developed by Julian R Seward. See here for copyright information. It exemplifies support for asynchronous capabilities in the flow graph API.

Building the example

cmake <path_to_example>
cmake --build .

Running the sample

Predefined make targets

• make run_fgbzip2 - executes the example with predefined parameters.
• make perf_run_fgbzip2 - executes the example with suggested parameters to measure the oneTBB performance.

Application parameters

Usage:

fgbzip2 [-b=value] [-v] [-l=value] [-async] [filename=value] [-h] [filename]

• -h - prints the help for command line options.
• -b - block size in 100 KB chunks, [1 .. 9].
• -v - prints diagnostic output to screen.
• -l - use memory limit for compression algorithm with 1 MB (minimum) granularity.
• -async - use graph async_node-based implementation.
• filename - name of the file to compress.
