Welcome to the COMPASS wiki.
The COMPASS platform relies on several layers of software. This stack is described in the following figure.
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 including optimized libraries : CUBLAS, CUFFT, CURAND
* the CArMA (C++ Api for Massively parallel Applications)
* 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 languages in order to build evolutive and modular higher level applications. For now only the Yorick interpreted language is supported through the Yorick API but plans exist to add Python support.
At the higher level, we find the Yorick plugins accessible to the user through the interpreter. This includes the YoGA plugin, providing general utilities to the user such as random number generation, fast Fourier transform or various BLAS levels. Additionally, the YoGA_AO extension provides a whole environment, including GUIs, to simulate adaptive optics systems.
