# Poplar Advanced Features Example This example performs a simple computation but uses more advanced features of Poplar than the tutorials. This includes: * Moving I/O into separate Poplar programs * Use of multiple programs * Use of PopLibs * Saving and restoring of Poplar executables * Skipping graph and program construction when restoring executables * Enabling Profiling * Choosing the number of IPUs * Choosing between IPU HW and IPU Model for execution ## File structure * `main.cpp` The main Poplar code example. * `Makefile` A simple Makefile for building the example. * `utils.h` Utility functions used by the example. * `codelets.cpp` A custom vertex used in the example. * `README.md` This file. ## How to use this example 1) Prepare the environment. Install the Poplar SDK following the instructions in the Getting Started guide for your IPU system. Make sure to source the `enable.sh` script for Poplar. The example also uses boost::program_options. You can install boost via your package manager. 2) Build and run the example. ``` make ./example --help ```
