On the contrary, we are very interested to get GPU support into GRASS.
Some discussions have already taken place:


See links therein for discussion about CUDA versus OpenCL. Please
don't hesitate to bring this up on the grass-dev mailing list since some
experts are not reading here to my knowledge.

A selection could be also driven by popularity of a module, say, some commands
are way more often used than others. I started a list in above mentioned Wiki
page which I'll send to grass-dev for discussion.

thanks for your interest,
