Intel® Threading Building Blocks. Sub_string_finder sample

# Intel® Threading Building Blocks.
Sub_string_finder sample

A simple example that uses the parallel_for template in a substring matching program. The Intel® Threading Building Blocks Getting Started Guide describes this example.
For each position in a string, the program displays the length of the largest matching substring elsewhere in the string. The program also displays the location of a largest match for each position. Consider the string "babba" as an example. Starting at position 0, "ba" is the largest substring with a match elsewhere in the string (position 3).
The code located in the sub_string_finder_extended.cpp file demonstrates offload programming for Intel® Many Integrated Core (Intel® MIC) Architecture (see build instructions).

System Requirements

For the most up to date system requirements, see the release notes.

Files

sub_string_finder.cpp
  The example as it appears in the Getting Started Guide.
sub_string_finder_extended.cpp
  An example similar to the one in the Getting Started Guide, but with an added sequential implementation, and with an offload region added that can be executed on Intel® MIC Architecture based coprocessor. The three implementations are timed, by using tick_count, and the speedup of the parallel version and the speedup of the parallel version and, if applicable, the offload version is calculated and displayed.
sub_string_finder_pretty.cpp
  An example similar to the one in the Getting Started Guide, but with more attractive printing of the results.
Makefile
  Makefile for building the example.

Directories

msvs
  Contains Microsoft* Visual Studio* workspace for building and running the example (Windows* systems only).
xcode
  Contains Xcode* IDE workspace for building and running the example (macOS* systems only).

Build instructions

General build directions can be found here.

Usage

`sub_string_finder`
  Runs the example as it appears in the Getting Started Guide.
`sub_string_finder_pretty`
  Runs the similar example with more attractive printing of the results.
`sub_string_finder_extended`
  Runs the example extended with a sequential implementation and an offload region that can be executed on Intel® MIC Architecture based coprocessor.
To run a short version of this example, e.g., for use with Intel® Threading Tools:
  Build a debug version of the `sub_string_finder_pretty` example (see the build instructions).
  Run it, e.g., `sub_string_finder_pretty`.
