Hobby: Scientific computing with highly unsuitable equipment
Thoughts about SETI and SETI@home
The reason for running SETI@home is contributing to an interesting project and also test out the unsuitable and slow computational equipment.
I would suggest trying to develop and streamline GPU-computation. Making it work on different operating systems is a bit tedious.
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
