Sourcecode

Hi, I have great interest in Cuda and OpenCl. Currently, I am trying to teach myself how to program in C/C++. I know that learning from practice would be far more effective than simply reading a book, therefore I like to port the code from the solvers to Cuda and later in OpenCl (also self-practice). So I was wondering, where can I find those sourcecode (from solvers) in Caelinux, if there's any.

Best regards,
Ying
