running two instances of miner software on gpu

[antony]

Hi,
I noticed running a bitcoin miner (poclbm) and a cpuminer with scrypt (litecoin) does not seems to slowdown either.
So has any one tried running multiple miners with different worker names? It seems there is room.

one miner is GPU and the other CPU that's why , but cpu mining is not cost effective if you pay for electricity
