The COMPASS platform comes with an user interface based on the Python language which rely on several layers of software. These stacks are described in the figures

The lower level is the GPU domain. This is where resides the computing power and the memory that needs to be addressed to perform the computations. To manipulate GPU arrays and use advanced and optimized numerical algorithms, COMPASS relies on 3 main pillars :

* the CUDA toolkit from NVIDIA including optimized libraries : CUBLAS, CUFFT, CURAND

* the CArMA (C++ Api for Massively parallel Applications)





    11
    
    
    
* SuTrA (Simulation Tool for Adaptive optics).

The intermediate layer is the binding domain. This is where the set of optimized tools are bound to interpreted language in order to build evolutive and modular higher level applications. This is achieved using Cython.

At the higher level, we find the python3 libraries accessible to the user through the interpreter. This includes the NAGA Python package, inherited from YoGA Yorick plugin, providing general utilities to the user such as random number generation, fast Fourier transform or various BLAS levels. Additionally, the SHESHA package, inherited from YoGA_AO Yorick plugin, provide whole environments in Python, including GUI, to simulate adaptive optics systems.
