I'll add another debugging tip to that one -
stop the tftp daemon service, then start it on the command line (as 
root) with the following flags:

-l -vv -s /path/to/your/tftpdirectory

The try Craig's tip - ie can you transfer a file by hand from 'localhost'
then reboot a compute node and follow the tftp request
