Dear Álvaro,

At this moment no IPOL server has a GPU with CUDA.
However, technically we could easily attach a GPU to any of the IPOL  
computing server and the system would automatically router the  
execution of these demos to the appropriate server.

I wouldn't advise to publish GPU code as the published main algorithm  
of an IPOL publication because normally the code is more difficult to  
read than a plain C/C++ with openMP. However, it's true that it could  
accelerate numeric libraries which use the GPU, and we could publish a  
fast version of the demo which uses the GPU code.

While the (new) IPOL demo system supports this routing without much  
problem, the decision of using a GPU, accepting GPU codes as  
publications, and to install the GPU itself is left for the Editorial  
Board and the system administrators.
