1# fgbzip2 sample 2fgbzip2 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. 3 4This example includes software developed by Julian R Seward. See here for copyright information. 5It exemplifies support for asynchronous capabilities in the flow graph API. 6 7## Building the example 8``` 9cmake <path_to_example> 10cmake --build . 11``` 12 13## Running the sample 14### Predefined make targets 15* `make run_fgbzip2` - executes the example with predefined parameters. 16* `make perf_run_fgbzip2` - executes the example with suggested parameters to measure the oneTBB performance. 17 18### Application parameters 19Usage: 20``` 21fgbzip2 [-b=value] [-v] [-l=value] [-async] [filename=value] [-h] [filename] 22``` 23* `-h` - prints the help for command line options. 24* `-b` - block size in 100 KB chunks, [1 .. 9]. 25* `-v` - prints diagnostic output to screen. 26* `-l` - use memory limit for compression algorithm with 1 MB (minimum) granularity. 27* `-async` - use graph `async_node`-based implementation. 28* `filename` - name of the file to compress. 29
