# Square sample Text filter that demonstrates the use of `parallel_pipeline`. Example program reads a file containing decimal integers in text format, and changes each to its square. ## Building the example ``` cmake <path_to_example> cmake --build . ``` ## Running the sample ### Predefined make targets * `make run_square` - executes the example with predefined parameters * `make perf_run_square` - executes the example with suggested parameters to measure the oneTBB performance * `make light_test_square` - executes the example with suggested parameters to reduce execution time. ### Application parameters Usage: ``` square [n-of-threads=value] [input-file=value] [output-file=value] [max-slice-size=value] [silent] [-h] [n-of-threads [input-file [output-file [max-slice-size]]]] ``` * `-h` - prints the help for command line options. * `n-of-threads` - the number of threads to use; a range of the form low\[:high\], where low and optional high are non-negative integers or `auto` for a platform-specific default number. * `input`- file is an input file name. * `output`- file is an output file name. * `max-slice-size` - the maximum number of characters in one slice. * `silent` - no output except elapsed time.
