 # Tutorial: Run Taichi programs in C++ application
 
-Taichi makes it easy to write high-performance programs with efficient parallelism, but in many applications we cannot simply deploy the Python scripts. Taichi offers a runtime library (TiRT) with a C interface so that your Taichi kernels can be launched in any native application. In this tutorial, we'll walkthrough the steps to deploy a Taichi program in a C++ application.

 ## Overview

-In Python, when you call a function decorated with `@ti.kernel`, Taichi immediately compiles the kernel and send it to the device for execution. This is called just-in-time (JIT) compilation. But generally speaking, we don't want to compile the kernels on a mobile phone, or to leak the source code to the users. So Taichi introduced ahead-of-time (AOT) compilation so that you can compile kernels on a development machine, and launch them on user devices via TiRT.

 1. Compile Taichi kernels from Python and save the artifacts.
 2. Load AOT modules with TiRT and launch them in your applications.
 
-Although this tutorial only demonstrates integrating Taichi in a C++ application, thanks to the versatility of the C interface, TiRT can communicate with many programming languages including C/C++, Swift, Rust, C# (via P/Invoke) and Java (via JNI).

 A compiled taichi kernel consists of all compiled artifacts when compiling a `ti.kernel` with the types of its parameters. Take kernel `add_base` as an example, argument `base`'s type is `ti.f32`. Its type information is used to compile the kernel and thus encoded in the compiled artifact, while it can be called with any floating point number at runtime.
