Hi Aniket,

thanks for considering Boost/uBLAS. Your potential mentor is David. If he
does not respond, just follow the instructions on the GSoC page and upload
your proposal.

Please note that we appreciate concrete (with code samples), realistic
(regarding time) and referring (to previous or pull requests) proposals.
Concrete examples inside the proposal will help us to understand intention
and it will demonstrate your experience and expertise.

Additionally, I advise to read

   - previous gsoc discussions on this or on the general boost mailing list
   - former gsoc student projects and proposals

to have a good feeling of the requirements.

Best,
Cem
