Hi, nice project. Can't handle to mine your coin via suprnv pool. I have 2 x 7950 and cgminer3.7.2 installed. Miner connection is ok, hashing looks like ok as well(1,1gh/s total for 2 cards), but 0 accepted or rejected shares - running 30 mins. Bat file is:
cgminer.exe -o stratum+tcp://grt.suprnova.cc:5947 -O xxx.worker:pass
surely you already got the answer but for all others interested in mining GRT:
according to
the original ANN it'a a SHA-256 PoW coin, so you'd better mine it with
Bitcoin ASICs

Yeap get an avalong6 or similarly priced miner, it would deliver more shares to ur share-receiver, however the main problem with that miner is poor quality of the internal parts and low reliability compared to bio miners that connect to ur nervous system and employ neurons of ur brain for to generate hashing power.
