A.- Please notice that, in order to use rCUDA, you should compile your code using the CUDA environment. That is, while compiling your application, rCUDA should not be used. You should compile your application as if it were going to be used with CUDA. Actually, it is good practice to check that your application works with CUDA (with a local GPU) before executing it with rCUDA.
