Hi Guru,
I have a 7 gpu miner. I don't have money to invest in more hardware but would like to improve the miner software.
As I know each gpu is finding the nonce to meet a block difficult. A nonce is a 32 bits number.
gpu sequential loop through the 32 bits numbers + block items -> hash?
or it randoms pick a number to do the hash?
When there are multiple GPU, how miner coordinate the GPUs to find a nonce effectively?
