Graphcore

Advanced Poplar 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
