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.
