This repository contains a "Hello World" introduction to building a small Legate library.
Users can begin by investigating the legate/hello/runtime.py file which demonstrates
the necessary code for setting up a LegateLibrary object, launching Legion tasks to
perform computations, and returning data objects that implement the __legate_data_interface__.
From there, users can investigate the files in the src/ directory. The src/hello* files
demonstrate how to register tasks with the Legion runtime using Legate APIs. Implementations of
various different task variants for CPUs, OpenMP, and GPU processors can be found in
src/task.cc and src/task.cu. The src/mapper.cc file shows a small customization to
a Legion mapper for mapping the tasks produced by the Legate Hello world example.
There is a test program in tests/hello.py that will demonstrate running the Hello
World library code in practice.
The install.py and setup.py scripts in this directory coupled with src/Makefile will
provide a good framework for setting up a build system for any Legate library.
