I think if Max got his Gpu miner, XPM deserves one too... Nothing is impossible. XPM is one of most original and unique coins out there.
It took
about 12 hours for cbuchner1 to crack Max and publish a GPU miner. Wasn't very difficult.
so... did this still not happen?
How is it impossible? The entire crypto community cannot get a GPU miner working for primecoin?
It takes a LOT of effort and smarts. Much more than Mtmlr is capable of and much more than anyone here in the forums is willing to put in - XPM is a virtually worthless botnet coin.
Can't forget the sour grapes?
Keccak is a different animal altogether...prime number math (integers) doesn't paralellize well, and gpu's strenght is massive paralell computing capabilities, so, yeah.
